Answer:
C) Y
Explanation:
The horizontal axis of the cladogram depicted below is a timeline that extends from 100,000 years ago to the present; the vertical axis represents nothing in particular. The labeled branch points on the tree (V-Z) represent various common ancestors. Let's say that only since 50,000 years ago has there been enough variation between the lineages depicted here to separate them into distinct species, and only the tips of the lineages on this tree represent distinct species.
- Y is the common ancestor of the greatest number of species, both living and extinct.
- V is the common ancestor of the fewest number of species.
- Eleven Species are both living and extinct, are depicted in this tree
- Evolutionary trees such as this are properly understood by scientists to be a hypothesis.
- Lamarck and Wallace are the two scientists below would probably have agreed with the process that is depicted by this tree.
Protein provides 4 calories per gram. Mary is on a diet that requires her to eat at least 40 grams of protein each day. She’s eaten 152 calories of protein today. How much more protein does Mary need to eat to meet her goal?
152/4=38g
2g is your answer
According to the Punnett square for this cross, 50% of offspring is predicted to have blue feathers. This is because the trait of a blue feather is dominant over the trait of a white feather. Thus, the correct option is B.
<h3>What is Punnett Square?</h3>
Punnett square may be defined as a kind of table in which all of the probable products for a genetic cross between two individuals with known genotypes are presented in a precise manner.
The complete question is described in the image given below:
When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.
In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).
Therefore, the correct for this question is B.
