Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.

Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green color. Thus, the correct option is B.
What is Chlorophyll?Chlorophyll is a pigment that is found in all green plants as well as some other species. It is crucial for the process of photosynthesis, which transforms light energy into chemical energy.
The chlorophyll pigment is in charge of giving plants their characteristic green hue since it does not absorb the green portions of white light; as a result, the plant reflects the particular light wavelength, giving it the appearance of being green.
Since chlorophyll is a poor absorber of the green and near-green portions of the electromagnetic spectrum, tissues containing chlorophyll are green in color. Chlorophyll absorbs light most powerfully in the blue and red portions of the electromagnetic spectrum.
So, the correct option is B.

Before receiving FDA approval, the tTAV protein had to be tested for any potential toxicities to other native animals. Why would this be part of the approval process?
Answers
Given what we know, we can confirm that toxicity testing would be necessary before receiving FDA approval in order to discard the risk of harming future recipients.
Why is this testing important?FDA toxicity testing for potential toxicities native to other animal species can be an essential part of any approval process. This part of the process ensures that the compound in question is free of toxins that not have been noticed in previous tests due to the innate resistance of the animal it was tested on, to begin with. This allows for a more thorough screening process and a safer end product.
Therefore, we can confirm that toxicity testing would be necessary before receiving FDA approval in order to discard the risk of harming future recipients.

If the 46 chromosomes are duplicated during interphase, why are there
still 46 chromosomes and not 92?
Answers
Before I talk about why there are still 46 chromosomes, I'll just review the basic chromosome structure. Each chromosome has a chromatid, with one centromere in the middle.
Chromosomes aren't counted by how many chromatids there are, but rather how many centromeres. When DNA duplicates, the chromatids replicate themselves, so each chromosome ends up having two sister chromatids joined at the same centromere.
There is the same number of centromeres in the cell, so there are still technically 46 chromosomes. However, there are 92 chromatids.
This used to be confusing for me too :) hope it helps!

Genetic drift Natural In evolution, which driving factor most consistently requires a small population as a precondition for its occurrence? Genetic drift Natural selection Nonrandom mating Mutation.
In evolution, Genetic drift is the driving factor which most consistently requires a small population as a precondition for its occurrence.
What is Genetic Drift?A change in the relative frequency of alleles within a population is an example of genetic drift. Natural selection, often known as the differential survival and reproduction of individuals across a population as a result of differences in phenotype, is one of the possible causes of this phenomenon.
Natural selection gives an advantage to some characteristics in a population, which results in certain individuals being able to reproduce while others, who have characteristics that give them a disadvantage, will provide their genes to subsequent generations. This will ensure that the allelic frequency of each successive generation will be distinct from that of the parent group.
Therefore, a subpopulation may become genetically diverse from its parent population due to genetic drift.

list 3 differences between sun leaves and shade leaves
Answers
Answer:
Partial sun is between four and six hours of sun a day. Partial shade is two to four hours of sun per day. Shade, in gardening terms, means less than two hours of sunlight a day. Leaves which grow in the shade ('shade leaves') are generally larger in area but thinner than leaves which grow in full sunlight ('sun leaves'). Sun leaves become thicker than shade leaves because they have a thicker cuticle and longer palisade cells, and sometimes several layers of palisade cells.
