Answer:
They can mimic a natural hormone and lock onto a receptor within the cell. The disruptor may give a signal stronger than the natural hormone, or a signal that occurs at the "wrong" time.
Explanation:
<em>2:4 homozygous recessive; 50% heterozygous.</em>
Explanation:
I will be using the letter B to represent dominant alleles and b to represent recessive alleles.
If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).
If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).
I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...
<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.
<u>50%</u> of the offspring will be <u>heterozygous</u>.
Mitosis or meiosis. I'm not sure of the answer. but if I had to guess I would say mitosis because from my understanding meiosis is only for reproductive organs...
It was during the Mitosis stage or the S-phase (Synthesis) of the Interphase. The cells spend most of their life in Interphase before Mitosis will occur.
