If the 46 chromosomes are duplicated during interphase, why are there
still 46 chromosomes and not 92?
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!

list 3 differences between sun leaves and shade leaves
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.

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?
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.

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.
