Here is the questions

I'll take a gander at your question

Explanation:

For the first one, take a look at it and assume that if you have Physical traits that your father/mother have, It means that it was genetic. Physical traits are things like appearance and how your body has formed.

This makes your answer A

If you ever need help with something like this. Just study how Genes affect the human body and what they do.

Nature vs Nurture, that points out towards C.

Genes being Nature, as they are completely natural. And Nurture, being the type of environment that the child is born in and how the parents care for the newborn child.

Answer is weight, depending on where the child has grown up. Their weight will be affected.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
