Answer:

Explanation:

Plant cells have cell walls around them, and animal cells don't have cell walls. The cell walls give plant cells their boxy shapes. That's nice for plants, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.

The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression- the nucleus is, therefore, the control center of the cell.

How do we know that height in humans is a polygenic trait?
Elena-2011 [213]
We know that height in humans is a polygenic trait because it has a lot of variation. The height gene is controlled by at minimum three genes with six different alleles. If all of these alleles are dominant for the tall gene you will be tall if you are dominant for the short gene you will be short if there is no clear dominance between the two genes you will fall somewhere  in the middle.

And I will be honest I have no idea what the survey is about but obviously your school (k12 maybe?) would not expect you to go around the neighborhood asking random people where their knuckle hair is located. All I can say Is try your best. Hope this helped. XD
