Detached ear lobe allele is dominant over attached ear lobe allele
<u>Explanation:</u>
Mendel is the one who found the reason why an offspring has characteristics of the parent. He found that some traits were exhibited in an individual while the others were not. So he named the expressive allele as dominant trait and the one which in not expressive as recessive trait.
He formulated a set of hypothesis and experimented it on the pea plant to form the “Law of Inheritance”. In humans the detached ear lobe, blood groups all are examples of the law of dominance. Hence Mendelian traits are the physical characters that are passed on from one generation to the other

I would say it's A because it sounds like the most important one.
Single-celled organisms exchange gases directly across their cell membrane. However, the slow diffusion rate of oxygen relative to carbon dioxide limits the size of single-celled organisms. Simple animals that lack specialized exchange surfaces have flattened, tubular, or thin shaped body plans, which are the most efficient for gas exchange. However, these simple animals are rather small in size.
The answer is C
Parasitism is the relationship between two animals, one is benefiting and the other is harmed. In this example, the tapeworm is benefiting by eating all the pig’s food, but the pig is harmed.
I hope this helped!!
