The complete question is as follows:
1. How did the green world hypothesis differ from this “bottom-up” view?
2. Imagine a simple food chain: Grass -> Grasshoppers -> Mice. If snakes that eat mice are added to the ecosystem, how would you redraw the food chain to represent this change?
3. After the snakes are added, would you expect the amount of grass to increase or decrease? Explain your reasoning.
Answer:
1. The green world hypothesis states that plants or producers are consumed in less quantity by herbivores due to predators and other conditions which is different from the hypothesis as it says the number of the herbivores are regulated by the organism above them in the food web instead of below.
2. before adding snake: Grass →Grasshoppers →Mice ( arrow towards predator)
After adding the sakes: Grass →Grasshoppers →Mice→Snakes. (as snakes eat mice so they will be added after mice)
3. The grasses will decrease as there would be fewer mice due to snakes and the number of grasshoppers will be high which leads to the decrease in the amount of grass.

Consumers: the Ae‘o (Hawaiian Stilt), the Alae Keokeo (Hawaiian Coot), the ‘Alae ‘ula (Hawaiian Moorhen),
the Koloa Maoli (Hawaiian Duck), fish, such as the Aholehole and the O‘opu (Goby).
Decomposers: bacteria and fungi.
Bugs, frogs and salamanders, fish, birds, snakes and turtles, and mammals like mice, squirrels, deer, and bears all like to use wetlands.
Alligators, snakes, turtles, newts and salamanders are among the reptiles and amphibians that live in wetlands. Invertebrates, such as crayfish, shrimp, mosquitoes, snails and dragonflies, also live in wetlands, along with birds including plover, grouse, storks, herons and other waterfowl.

A woman heterozygous for polydactyly (extra fingers and toes), a dominant trait, is married to a normal man. What is the probability of producing an offspring that has extra fingers or toes?
Answer:
The correct answer is -50%
Explanation:
Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele
So, the heterozygous woman will be - Pp & the normal man will be - pp. The presence of one allele of polydactyly will be able to show its effect as it is dominant.
Cross between heterozygous woman & normal man:
Gametes:
P p
p Pp (Show polydactyly) pp (Normal phenotype)
p Pp (Show polydactyly) pp (Normal phenotype)
From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.
Polydactyly is a condition that occurs wherein individuals have more than the normal amount of fingers and toes. It is also a genetic condition and as well heritable.
The probability of producing an offspring with extra toes or fingers in a cross between an heterozygous and a normal is 50%.
Let P represent the dominant and p the recessive
Pp (heterozygous) and pp (normal)
(woman) P p
(man) p Pp pp
p Pp pp
50% 50%
Therefore, the probability of producing an offspring with extra toes or fingers (Pp) is 50%.

Answer:
According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.
Explanation:
G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.
G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.

What impact on plants due to depletion of nitrates or nitrogen?Nitrate plays a very important role in the ecosystem and due to presence of nitrogen plants grow fastly and produce large size of fruits and flowers.
Nitrate has a common inorganic ion found in the plants that has to be required for the proper growth and development of the plant.Many growers including nitrates in their nutrient regiment just to stimulate plant growth. Plants has acquired much nitrate through root intake from the soil and water present around them.
Hence due to the depletion of nitrogen, plants are getting turning to yellow and this shows that it produces smaller fruit. In modern era farmers has been adding nitrogen containing fertilizers which produce large amount of grains, foods and fruits which is also free from diseases.

which change would lead to higher carbon dioxide levels in the atmosphere
A. An increase in photosynthesis
B. An decrease in animal
C. An increase in the burning of fossil fuels
D. An decrease in the destruction of forests
An increase in the levels of fossil fuels results in higher carbon dioxide levels in the atmosphere. So the correct option is C.
What are fossil fuels?The components of fossil fuels are decaying plants and animals. These fuels may be burnt to provide energy and can be found in the crust of the Earth. An example of fossil fuel is coal, as well as oil and natural gas.
Coal is a substance that is typically found in sedimentary rock formations, which are collections of rock, dead plant and animal materials, and layers of silt. A chunk of coal must contain more than 50% fossilized plant material.
Shale is one sedimentary rock type that contains oil in its native form. The thick oil that may be used to generate gasoline is created by heating this substance. Typically, pockets of natural gas can be found atop oil deposits. Additionally, sedimentary rock strata devoid of oil might contain it. Methane is the main component of natural gas.
Therefore, an increase in the burning of fossil fuels will result in higher carbon dioxide levels in the atmosphere. So the correct option is C.

What molecule does blank with letter A represent in the reaction above?
O carbon dioxide

O oxygen
O ATP
Answer:water
Explanation:
During photosynthesis 6 molecules of carbon dioxide are required to synthesize a glucose molecule, hence option a carbon dioxide is correct.
What is the reaction of photosynthesis?Six carbon dioxide molecules are required, one for each carbon atom in glucose. As a byproduct of water oxidation, 6 molecules of oxygen are created, 6CO2+6H2O→C6H12O6+6O2.
The endergonic pathway requires free energy, which is provided by sunlight. Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.
Organisms primarily employ two types of molecules: glucose and ATP. Both compounds are used as fuels by all living things. Both chemicals are also important in the photosynthesis process.
Therefore 6 carbon dioxide is used in reaction, hence option a carbon dioxide is correct.

3)muscle cells
4)liver cells
5)stomach lining cells
Answer:
3 because the muscle cells is produced
Red blood cells are produced more frequently than the other types, the body produces them every second, hence option 2 is correct.
Why do red blood cells produce more frequently?Medication that promotes the formation of RBCs: Erythropoietin is a hormone that is made in the liver and kidneys and stimulates the production of RBCs in the bone marrow. Some types of anemia can be treated with erythropoietin.
In order to replace those red blood cells that eventually deteriorate and die, red blood cells are continuously created in the bone marrow. A red blood cell has a lifespan of roughly 120 days on average. Anemia and shortness of breath result from a large drop in the number of red blood cells.
Therefore, It just takes a few weeks to replenish red cell reserves because your body produces roughly 2 million new ones every second.

Nitrogen is required for protein formation. What is responsible for the bulk of nitrogen fixation?
A.
air
B.
animals
C.
bacteria
D.
lightning
Answer:
The factor with the responsibility for nitrogen fixation is bacteria (option C).
Explanation:
The nitrogen that contributes to the formation of proteins comes from plants. Due to the inorganic nature of nitrogen, plants require bacteria to contribute to the assimilation of this element, a process called biological nitrogen fixation.
Nitrogen fixing bacteria in plants are called diazotroph and, in some cases, establish a symbiosis with the plant's roots, the rhizobia.
The other options, air, animals and lightning, do not correspond to biological nitrogen fixers with the ability to incorporate nitrogen into plants.What are three other names that mean the same thing as “cell membrane"?
