Answer:
I'd say nuclear, because of the dangers associated with producing it.
Explanation:
Answer:
C
Explanation:
First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
An allele is a variation of a gene that can be expressed as a phenotype.
Explanation:
Genes are the specific sequences of DNA that code for a particular protein in organisms. When the fertilization occurs each parent contributes one chromosome which is homologous this means that both will have genes on the particular loci. The alleles of the particular genes will come together to express the trait.
Allele is an entity of gene which determines how the gene will express the particular trait like tall, short, round, wrinkle etc. It can be said that allele determines the phenotypic trait of a particular gene.
A theory is an explanation of an aspect of the natural based on careful examination of facts. A theory by its definition can be repeatedly tested. A theory can be changed or replaced because of the following reasons:
New technology is developed that provides more information about the theory. (New technologies can lead to new results).
New experimental methods are designed to test a theory.
New information is discovered that does not support the theory.
