The evolutionary adaptions to different environments are responsible for the variation in shape and function of the tetrapod forelimbs. It has been a common thing for organisms in the past to develop its certain body parts as an instinct to adapt the changes in its environment for survival.
I believe it would be D, since the animals that had more food, and a advantage, would produce and so on.
Hemophilia is an inherited bleeding disorder where clotting factors are either absent or present in low amounts. As a result, the blood doesn't clot. It is an X-linked recessive trait that is inherited.
<h3>What is X- linked recessive genetic illness?</h3>
Genetic abnormalities known as -X-linked recessive genetic illnesses are brought on by an atypical gene on the X chromosome. "Carriers" for a disease are females who have the disease gene on one of their X chromosomes. The fact that carrier females have a second copy of the gene to make up for the copy with the disease-causing alteration or mutation usually prevents them from showing symptoms of the ailment.
A male has one X chromosome, thus if he gets an X chromosome that carries a gene that causes a disease, the condition will manifest in him. Male X-linked If the other X chromosome from their mother is healthy, all of their daughters will carry the illness gene.

All forms of RNA are intermediate molecules that are fabricated within DNA to perform cellular functions.
mRNA - messenger RNA carries selected portions of DNA used to fabricate polypeptides used to fabricate amino acids for protein.
tRNA - transfer RNA is comprised of select genetic code and transfers amino acids to ribosomes for assembly
rRNA - ribosomal RNA is comprised of select genetic code and makes the ribosomes
RNA is highly mutatable, highly reactive, non-reproductive, and highly specialized metabolically, and consequently totally unsuitable for consideration of any pre-DNA senario being posited for the origin of life.
D i believe, i could be wrong though
