The correct answer for the question "A student looks at a slice of tissue on an unlabelled microscope slide. the student concludes that the tissue is not from an animal because the cells in t<span>he tissue have" is D. Cell walls. When we compare animal and plant cells, only plant cells have cell walls. Cell walls are formed because of cellulose. </span>

In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.
