what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part E
Answer:
What the scientist is doing incorrectly is working on a computer console with several monitors, having tubes and flasks of chemicals or biological substances on the same work table, many of which have fallen to the floor breaking and spilling their contents.
Explanation:
In the image it can see that a scientist works with a computer, placed in a long table where there are a lot of flasks and test tubes, many of which contain substances and have fallen to the ground, breaking and perhaps spilling their contents. This is a incorrect practice, as there should be a console for the computer, while the laboratory material should be on separate work tables.
what could he do to make their work in the lab safer? Separate the work spaces by having a computer work area separate from the lab area.Keep the work area clean, avoiding falling containers and spilling chemical or biological substances.why is it important to follow these procedures?Following these procedures is important to maintain biosafety standards and avoid accidents that affect the work in progress or the health of staff.
Not all plant cells contain chloroplasts. What is the most likely reason for this?
Plant cells are defined as eukaryotic cells that are autotrophs and are capable of photosynthesizing. All plant cells do not contain chloroplasts as no sunlight reaches that area.
What is chloroplast?Chloroplasts are the organelles of the plant cell constituted of the green-colored pigment called chlorophyll. This pigment is crucial for photosynthetic reactions as they capture the solar energy required to convert the reactants.
The plant parts like underground organs (root system) and inner stems lack chloroplast in their cells as no sunlight reaches that area, hence they are of no use in those systems and organs. They are not exposed to sunlight and cannot photosynthesize.
Therefore, all plant cells do not contain chloroplast as they do not undergo photosynthesis reactions.

select the correct answer sickle cells  disease is a hereditary mutation that causes The red blood cells to the form decreasing their ability to carry oxygen based on the image what kind of mutation occurs to cause Sickel cell disease
Answer:
Sickle cell disease is due to a type of substitution mutation.
Explanation:
Sickle cell disease is a condition that is transmitted from parents to children in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
The mutation that occurs in sickle cell disease is due to an alteration in the β-chain of hemoglobin, caused by the substitution of thymine base by adenine in the DNA that determines it. As a result, valine replaces glutamic acid in the β-chain amino acid sequence, with the consequences described.
The other options are not correct because deletion, duplication and translocation correspond to chromosomal mutations, not responsible for sickle cell disease.What is the main function of the circulatory system in multicellular organisms?

If an organelle is selectively
permeable what can we infer
about its function?
MULTIPLE CHOICE
Answer:
What can be inferred about the function of a selectively permeable organelle is that organelle allows some molecules to pass trough (option C).
Explanation:
Selective permeability is a characteristic, present in the membranes, which allows the passage of some substances and prevents the passage of others, according to their structure.
An example of selective permeability is found in cell membranes, whose hydrophobic nature allows the passage of apolar molecules easily, limiting or preventing the passage of polar molecules and ions.
The other options are not correct because:
A. Not all molecules can pass through a semi-permeable organelle.
B. The semipermeable organelle does not prevent the passage of any substance.
C. Semi-permeable organelle does not allow the passage of large molecules easily.

Patterns of inheritance are usually more complicated than what is predicted by Mendelian genetics. Explain four possible exceptions to Mendelian genetics involving the inheritance patterns of a single gene and provide an example of each.
Answer:
Please find the explanation of the four possible exceptions to Mendelian genetics below.
Explanation:
Genetics, generally, has to do with how genes are inherited or transferred from parents to offsprings. Gregor Mendel, however, explained this concept in his principles of inheritance called Mendelian genetics. There are, however, exceptions to this mendelian principle called Non-mendelian pattern of inheritance i.e patterns of inheritance that do not follow Mendel's principles. Four of them are explained below:
- Incomplete dominance- This non-mendelian inheritance pattern occurs when one allele of a gene does not completely mask its allelic pair, but instead forms an intermediate phenotype. This is in contrast with Mendelian genetics that proposes complete dominance. For example, a red and white flower produce a pink flower (intermediate).
- Codominance- This is another non-mendelian inheritance where two alleles of a gene are simultaneously expressed. For example, roan cattles is a combination of both red and white hairs.
- Multiple alleles: Some traits in a population are controlled by more than two alleles, as explained in mendelian inheritance. Examples of trait controlled by multiple alleles is height in humans.
- Sex-linked inheritance: Some traits are controlled by genes on sex chromosomes i.e. X and Y chromosomes. This genes exhibit inheritance pattern that are different from Mendel's. Example is haemophilia disease controlled by an affected gene on the X-chromosome.
what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part d
Answer:
What the scientist is doing incorrectly is disposing of a chemical or biological waste in the common sewer.
Explanation:
One of the most important biosecurity measures is the proper disposal of chemical and biological waste. What the shown scientist is doing incorrectly is disposing of potentially harmful substances in a normal sewer.
What could he do to make their work in the lab safer?The main thing that must be done to maintain a safe laboratory is to perform proper disposal of chemical or biological waste, which must be placed in airtight containers and transported to a location for safe disposal.
Chemical waste is usually taken to a landfill where it can be neutralized. Biological waste is transported to incinerators for complete disposal. Why is it important to follow these procedures?Following these procedures is important to avoid chemical or biological contamination of both the environment and people.

1. Negative feedback is bad for your body. True or false 2. Both negative and positive feedback works in a loop. True or false. 3. Feedback loops are open systems of information. 4. There are feedback systems found in the environment and mechanical systems.
Answer:
1. False
2. True
3. True
4. True
Explanation:
Negative feedback (or balancing feedback) happens when some capacity of the yield of a framework, cycle, or system is taken care of in a way that will in general decrease the variances in the yield, regardless of whether brought about by changes in the input or by different unsettling influences.
Though certain feedback will in general prompt unsteadiness through outstanding development, wavering or disorganized conduct, negative feedback for the most part advances steadiness. Negative feedback will in general elevate a settling to balance, and diminishes the impacts of bothers. Negative feedback loops in which the perfect measure of adjustment is applied with ideal planning can be entirely steady, exact, and responsive.

Which function is performed by Earth's magnetic field?
O A. Charged particles from the sun are prevented from reaching Earth.
O B. Light radiation is converted to heat energy.
O C. Magnetic charges from space are prevented from reaching Earthis
O D. Utraviolet rays from the sun are prevented from reaching Earth.
surface.
Answer:
D. Ultraviolet rays from the sun are prevented from reaching Earth.
surface.
Explanation:
What little is known is that the Earth's magnetic field creates the so-called "magnetic shield" that provides protection against some other dangerous forms of radiation, namely cosmic rays and solar wind.
While there is no danger of losing the Earth's gravitational field, the Earth's magnetic field is declining faster than any other geophysical phenomenon. This continuous loss of the Earth's magnetic field, and the associated increase in harmful radiation, are beyond human control.

a farmer wants to know which will allow his plants to produce the most food. he gave no fertilizer to 10 plants fertilizer a to 10 plants and fertilizer b to 10 plants. all of his plants were the same were planted in the same soil and we given the same amount if water after six weeks the farmer weighted the total amount of food produced by each group
Answer:
It depends on the optimum dosage of NPK.
Explanation:
The farmer gain more productivity from that type of fertilizer which have optimum dosage of nitrogen, phosphorus and potassium fertilizers because these three fertilizer needed by the plant in large quantity and having great contribution in the yield of plant so if ''fertilizer a'' has optimum dosage of these three nutrients so we can say that ''fertilizer a'' produces more food as compared to no fertilizer and ''fertilizer b'' whereas if ''fertilizer b'' has optimum dosage of these nutrients so ''fertilizer b'' produces more food.
Using its long tail and long hind legs, the Ord's kangaroo rat can jump 2 m in the air as it hops away from predators, such as snakes and owls [A, 4 marks] a. How would Lamarck account for the origin of the long hind legs of the Ord's kangaroo rat? b. How would Darwin?
Answer and Explanation:
a. According to Lamarck, the origin of the long hind legs of the Ord's kangaroo rat is acquired due to extensive use of the muscle legs to jump. Such physical characteristics could be transmitted to future generations. This theory is called Neo-Lamarckism.
b. Darwin, on the other hand, theorized that in a population of Ord's kangaroo rat, there was an individual whose characteristics, long tail and hind legs, had more chances of escaping its predator and, consequently, could survive and reproduce. This theory is called Darwinism.
