A geneticist wishes to determine if a red rose of a certain variety is homozygous for the color red.
If red is dominant over white, the red rose should be cross-pollinated with roses of the same variety that are:

A) homozygous red.
B) homozygous white.
C) heterozygous red.
D) heterozygous pink.

Explanation:

1. As given, Red is dominant on white.

And a geneticist wants to determine that red rose of certain variety is homozygous for the red color.

2. Here if red is crossed with pure red, the geneticist can not determine the red gene if it is dominant or recessive.

3. So, the red rose should be cross-pollinated with roses of same variety that are homozygous white.

Finally the answer is  B (homozygous white).

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

the answer is c. it will give up it's valence electron to the other atom.
