To solve this problem on genetic dominance, we will need a punnet square.

Let's let P represent purple-flowered and p represent white-flowered.

We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.

       <u>P</u>     <u>P</u>
p|    Pp   Pp

p |   Pp   Pp

As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.

Since each flower has a dominant and recessive allele, they are heterozygous.

Therefore, the solution to this problem is D.

A prepared slide of an organism shows red cells after acid-fast staining. Therefore it can be concluded that the cells
nasty-shy [4]
It can be concluded that the cells CONTAIN ACID FAST BACTERIA.
Acid fast staining is a staining technique that is used to differentiate two types of gram positive cells, those that have waxy mycolic acid in their cell wall and those that do not. 
Those cells that do not have mycolic acid in their cell wall will show blue color after acid fast staining.<span />
