In how many directions can energy be cycled?
Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level.
I hope that this helps you understand. I hope that you and your family are well, please stay home and stay safe. With all that said, have a wonderful day
Answer:
There is a 50% chance of getting Huntingdon's disease.
Explanation:
Assume the affected parent is Hh, where H is the Huntingdon's disease allele and h is the unaffected allele. One parent is unaffected, or hh. You have a 50% chance of getting the H allele from the affected parent.
If I had the choice to get tested, for Huntingdon's disease, I would do it. I would want to know so that I wouldn't live my life worrying about it everyday.
Meiosis takes place in the gonads of most organisms.
So the correct answer is A : Gonads.
Hope this helps :)

Dark fur color appears to be an adaptation for mice living in dark environments, as both the frequency of the characteristic and the allele that generates it have altered. These findings further back with the theory that selection is context-dependent, as dark mice were preferred in some contexts but not in others.

What is mutation?</h3>
A mutation is defined as a change in the sequence of genetic letters, called bases, within a molecule of DNA.
In a population, more offspring are born than can survive, resulting in competition among people. Individuals that possess a certain trait are more likely to live and/or produce more offspring than those who do not possess that trait. The context in which a species exists influences its selection. Characteristics that are advantageous in one setting may be detrimental in another.
New mutations cause black color.
- Fur color is controlled by many genes (4:29).
- Most genes are identical, but dark and light rock
- pocket mice differ in one gene (Mc1r; 4:55).
