natural selection explain the change with time of darker mice into lighter mice? Because predators could more easily spot the dark mice on light sand. The lighter mice were more likely to survive and have offspring. Over time, the population became light colored.
The probability of Sean to both sing and dance well is 50%.
<h3><u>Explanation:</u></h3>
The gene that is dominant is expressed in phenotype of the individual and the genes are actually obtained from the parents.
Here two characters are mentioned which are singing and dancing.
The dominant character i.e able to sing is marked by gene S and the corresponding recessive allele is marked by gene s.
Similarly, the ability to dance is marked by gene D and recessive allele is marked by gene d.
So, the mother is heterozygous and she can sing well, but can't dance. So her genotype is Ssdd.
The father can't sing and is homozygous, so his genotype is ssDD.
Gametes from the mother is Sd and sd. While the gamete from the father is sD.
So the probabilities of the progenies are SsDd and ssDd.
So the probability of Sean to both sing and dance well is 50%.
<span>Anemia
is a condition that occurs in blood in which a person lacks enough healthy
blood cells or haemoglobin. The latter is the main part of the red blood cells
which binds with oxygen and transports it to the rest of the body. One of the
causes of anemia, as mentioned above, is fatigue. The condition can also be
associated with the deficiencies in vitamins and minerals (iron). </span>
All living things contain carbon. Carbon moves through every level of a food chain and food web. When living things die, the remains decompose, cycling the carbon back into the ecosystem.
I think the answer is A. Growth in respond to touch.
