The correct answer is - B. Beak size determines what the bird can eat.
The beak of a bird can come in many different shapes and sizes. It can be pointy, long, short, rounded, scythe-like, thin, thick... All of those shapes and sizes have a specific role, and that role is to enable the bird to feed itself with certain type of food source. Every food source requires certain type of beak in order for the bird to be efficient in getting its nutrition, so depending on hat the bird eats, we can easily see a pattern in the beaks, where birds that eat nuts have one strong and shorter beak, the ones that eat warms and insects have thin, pointy one, the predator birds have claw like, sharp beak...

Answer: It is important to conduct many different experiments and estimates in a project for having as much statistic data as possible, because it is necessary to show proof on whichever project you are into. In order to avoid confusion, it's also possible to <u>organize data in Excel sheets/tables so it can be visually easier to interpretate</u>. <u>Gut instinct isn't enough to prove something wrong or righ</u>t, and <u>few data means higher probability of things going in ways other than the expected</u>.
Answer: 20%
Explanation:
Recall that the sum of all nitrogenous bases is equal to 100%.
Hence: A + C + G + T = 100%
Now, since adenine nucleotides is 30%, then thymine is 30% as well (A = T). Thus, the total of both is 60%.
From 100 remains 40% which is divided equally between guanine and cytosine, so each is 20%.
Thus, the percentage of the same DNA molecule that would be expected to be guanine nucleotides is 20%
The answer is A . nucleus and the cytoplasm.
