Answer:
Chemical.
Explanation:
Chemical energy goes through the plant cells and then gets used up in different processes.
Answer:
50%
Explanation:
According to the given information, the woman has normal BRCA alleles while the man carries one copy of the mutated BRCA allele (BRCA1). A diploid organism such as human beings can have two BRCA alleles. A child gets one BRCA allele from the mother and the other from the father.
The child of the couple would get one normal allele from the woman. However, with respect to the BRCA allele, the man would form two types of gametes in equal proportion. The 50% of his gametes would have the mutated BRCA1 allele while the rest 50% would carry the normal BRCA allele. Therefore, the man can transmit either normal or mutated BRCA allele to the child. So, there are 50% chances for the child to get the mutated allele.
Answer:
Other variables that could have been taken into account are size, variability of shape in its wings and degree of darkening in its wings.
Explanation:
Of the three named variables, I believe that the degree of darkening is the most important since in this way we can realize the association of its color with environmental pollution, and thus be able to look for a cause-effect relationship.
