sorry, have a good day and life lol
The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart.
Answer:
A. Primary dimensions are less changeable, while secondary dimensions can change and are less visible.
Explanation:
The differences between primary and secondary dimension of diversity are as follows -
A) Primary Dimension
a) Primary dimension are those which are salient and hence they cannot change
b) Some common examples of primary dimensions are - ethnicity, sexual orientation, ethnicity, gender, race, physical abilities/qualities, age etc.
A) Secondary Dimension
a) Secondary dimension are not only limited to specific features and hence they can change with time.
b) Some common examples of secondary dimension are - geographic location, marital status, parental status. work experiences, educational background, income,military experience, religious beliefs, etc.
Hence, option A is correct
Q1. The answer is 53 chromosomes
Zebra has 44 diploid chromosomes (2n = 44). Zebra's gametes are haploid, so they will have 22 chromosomes (n = 22).
Donkey has 62 diploid chromosomes (2n = 62). Zebra's gametes are haploid, so they will have 31 chromosomes (n = 31).
After fusion of zebra's gamete (n = 22) and donkey's gamete (n = 31), the zonkey's zygote will have 22 + 31 = 53 chromosomes
Q2 and Q3. In the meiosis, the number of chromosomes is reduced by half. Since zonkey has 53 chromosomes, after meiosis it should have 53/2 chromosomes, which is not the whole number. This is the reason why they cannot produce normal gametes that will result, after the fusion, in the production of normal diploid zygote
