Answer:
1. Increase the use of green renewable energies
2. Promote recycling
3. Controlling industrial greenhouse CO2 emissions from the transportation sector
4. encourage the use of non-polluting means of transport (e.g., walking over road transport)
Explanation:
First, renewable energies are energy sources generated naturally without the use of fossil fuels (e.g., solar energy, wind energy, geothermal energy, etc). Thus, these green energies can replace the use of fossil fuels in a sustainable manner, and therefore reduce the emission of greenhouse gases such as carbon dioxide (CO2). Second, recycling can drastically reduce the amount of energy required to synthesize new products and reduces the need for new materials, being thus also useful to reduce CO2 emissions that result from extracting virgin materials. Third, the industries from the transportation sector produce the largest part of greenhouse gas emissions, thereby encourage the use of green energies in this area may represent a good alternative to reduce CO2 emissions. Finally, it is well known that urban transport generates about 40% of all CO2 generated by road transport, and thereby invest in green transport systems such as bicycling and walking may also represent a useful strategy to reduce CO2 emissions.

2. Which explanation for the increase in genetic diversity of this red panda population is supported by this data?
(1 point)
Red pandas in this population have encountered new predators due to the increase in deforested land, and this new predation pressure has selected for different adaptations.
Red pandas in this population have increased the number of cubs birthed by each mother every year, and this increase in population has resulted in more genetic diversity.
Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
Red pandas in this population have started eating a new diet due to the increase in deforested land, and the new dietary conditions have selected for different adaptations.
5. Which of the following scenarios would reduce the number of inheritable traits in a population, causing the individuals in that population to remain very similar to one another?(1 point)
A swamp that is being drained in order to build houses.
A forest that is being converted into farmland.
A lake that is drying up due to shifts in river flow.
A desert that has existed for millennia.
Answer:
2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
5. D - A desert that has existed for millennia.
Explanation:
2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.
5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.
I truly hope my answers and explanations can help you on this assignment! Be blessed! Be awesome! You've got this!
explain how the adaptation to reproduce quickly is beneficial in bacteria's ability to
develop resistance to antibiotics
Answer:
Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.
Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

11. There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
12. Nutrition is necessary for the growth of new cells and the replacement or repair of worn-out cells. Nutrition gives energy for different metabolic processes in the body. Nutrition is required to produce resistance against different diseases.
13. trypsin
14. salivary amylase
15. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.
16. Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.
17. Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

urethra → ureter → bladder → nephron
nephron → ureter → bladder → urethra
urethra → bladder → ureter → nephron
Answer:
Option 3
Nephron -> Ureter -> Urinary Bladder -> Urethra
Answer:
c
Explanation:
A group of students wants to study the structures of animals in the desert. One question they should ask is-
How long do the animals live?
Can you buy the animals in pet stores?
How do the animals satisfy their need for water?
How many offspring do the animals have?
From studies and research, I believe the proper question would be:
"How do the animals satisfy their need for water?" or "How long do the animals live?"
Explanation 1:
When studying the desert, asking "Can you buy the animals in pet stores?" is not going to help you find information about the desert because it is not a question to get information about the desert, only information if you just buy it at your local pet shop.
Explanation 2:
Asking "How many offspring do the animals have?" does help us learn about animals, but we are trying to find information on the structure of the desert in which the animals live in. We are not looking for how many children the animals will have because it doesn't fully relate to the question we would be asking.
Side Note: Offsprings mean children.

For each scenario below, list the body systems involved and their function during the specific activity.
Regulation / Homeostasis
You get too hot or too cold:
Your diaphragm expands and contracts so you can breathe:
Nutrient Absorption
The reactants needed for cellular respiration are taken in and transported to your cells:
Defense from Illness
A pathogen enters your body through a cut:
Defense from Injury
A bunny is running away from a wolf:
Your hand gets too close to a flame:
Reproduction
A woman’s body prepares for a pregnancy:
A woman’s body prepares for a birth:
Answer:
Regulation / Homeostasis you get too hot or too cold:
If you get either too hot or too cold, sensors in the periphery and the brain tell the temperature regulation center of your brain—in a region called the hypothalamus—that your temperature has strayed from its set point.
Your diaphragm expands and contracts so you can breathe:
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
Nutrient Absorption
The reactants needed for cellular respiration are taken in and transported to your cells:
cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells.
Defense from Illness
A pathogen enters your body through a cut:
The skin and mucous membranes act as a physical barrier preventing penetration by microbes. If the skin is cut then the blood produces a clot which seals the wound and prevents microbes from entering.
Defense from Injury
A bunny is running away from a wolf:
Rabbits have keen senses of smell, sight and hearing, which help them defend themselves from danger. When they sense a nearby predator, they innately freeze in place to camouflage with the landscape.
Your hand gets too close to a flame:
Skin is difficult to ignite, and usually chars in the presence of heat. It takes up to 10 minutes of direct flame for skin to crack open and start leaking out rendered fat. Even if a horse's body started to leak fat, it would be unlikely to go up in flames on its own.
Reproduction
A woman’s body prepares for a pregnancy:
Every month, usually one egg grows within a structure called the egg follicle (a fluid filled sac that nourishes the egg). The follicle produces estrogen, which helps a woman's body prepare for pregnancy by growing a new lining for the uterus.
A woman’s body prepares for a birth:
As your body prepares for birth, your cervix — the muscular ring between your uterus and vagina — begins to soften, dislodging the mucous plug.
Many scientific explanations for the origin of DNA and life have been proposed over the years. These hypotheses explain how
inorganic molecules became organic monomers, such as amino acids, sugars, phosphates, and bases. But this still didn't explain
where living things came from. If macromolecules were able to form on early Earth, this still leaves us with the question of how
the polymers would have become self-replicating, a basic criteria for life. There are several ideas but little certainty. Some of the
common ideas include: the RNA world hypothesis, the genes first hypothesis, and the metabolism first hypothesis."
Which of these statements is proposed by the genes first hypothesis?
A)
RNA is highly stable.
B)
The first life forms were self-replicating nucleic acids, such as RNA or DNA
RNA is able to store and pass on genetic information.
D)
RNA contains less nitrogen bases than DNA and thus, is a simpler molecule.
E)
Ribosomal RNA (TRNA) and transfer RNA (TRNA) are the primary molecules
responsible for protein synthesis.
The first life forms were self-replicating nucleic acids, such as RNA or DNA, RNA is able to store and pass on genetic information.
What is the difference between RNA and DNA?There are two differences that determine DNA from RNA,
(a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose, and
(b) RNA has the nucleobase uracil while DNA contains thymine.
Thus, options, A and C are correct, RNA is adapt of both storing genetic data and catalyzing chemical responses.

The graph represents the distance a car travels over time while on the highway. Which statement about the car's trip is accurate?
A)
The car does not move over time.
B)
The car travels at a constant velocity.
The car's velocity increases constantly over time.
D)
The car's velocity decreases constantly over time.
Answer:
B
Explanation:
The chart is going up and up which means the car goes up and up in speed and velocity and is very consistant
The statement that is accurate regarding the car trip is that it travels at a constant velocity. The correct option is B.
What is velocity?Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.
The rate of change of displacement is known as velocity. The rate at which velocity changes is called acceleration.
Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.
An object must move at a consistent speed and direction in order to have a constant velocity.
The object can only move in a straight line if the direction is constant. So, motion in a straight line at a constant speed is defined as having a constant velocity.
Thus, the correct option is B.

Answer:
Explanation:
This is an example
A. The following food chain in a simple terrestrial ecosystem:
Grass → Grasshopper → Frog → Snake → Hawk
B. The energy flow will be directed as follows:
grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)
Food Chain:
Consider the following food chain in a simple terrestrial ecosystem:
Grass → Grasshopper → Frog → Snake → Hawk
In this food chain, the grasshopper is the major producer, the frog is the secondary consumer, the snake is the tertiary consumer, and the hawk is the quaternary consumer.
B. Flow of Energy:
The giant arrow representing the flow of energy through the food chain would start with grasses and progress through each trophic level. Energy moves along the food chain in a way that passes from one organism to another when it is consumed.
The energy flow will be directed as follows:
grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)
The arrows indicate that the sun's energy is taken up by the grass through photosynthesis and then transferred to each successive level when the organism consumes it.

There is a direct relationship between the number of pollinating plants and the number of honeybees. Each population is dependent on the other for their survival and ultimately reproductive success.
Answer:
Both depends on one another.
Explanation:
Yes, there is a direct relationship between the number of pollinating plants and the number of honeybees because honeybees are insects that are responsible for pollination in the flowering plants. The population of flowering plants also has a great effect on the survival of honeybees because these flowering plants provides food in the form of nectar on which these honeybees survive and make honey from it. So we can say that both flowering plants and honeybees depends on one another for the successful growth and development.
fill in the blanks to complete the concept map for the process of translation
Answer:RNA code for Amino Acids that make Proteins through the process of translation
Explanation:
During translation, tRNA recognizes the mRNA codons, complements them, and add the correct amino acid to the growing protein. CODON and PROTEIN are the missing words.
--------------------------------------------------------------------------
Protein synthesis
Occurs in two steps. Transcription and translation.
Transcription ⇒ mRNA syntheis
The first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
Translation:
⇒ Cytoplasm stage
• Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
• Once in the cytoplasm, mRNA meets a ribosome, which is the primary structure for protein synthesis.
• Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
• While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
→ mRNA is composed of different codons.
→ Each codon is a chort sequence of
three nucleotides that codes for one amino acid.
→ When tRNA molecules recognize these
sequencies, they add the correct amino
acid to the growing protein.
⇒ Protein synthesis ends when the proteins passes through the Endoplasmic Reticulum and the Golgi complex for their final folding process.
