Partly genetic from body type, but most of it has to be acquired to be able to be good at athletic abilities <span />
Answer:
1. Based on their physical features and conduction properties
2. 80m/s to 120m/s
3. Has both sensory fibers and motor fibers
4. Group B conduct at 3m/s to 15m/s
5. Group C conduct at 0.5m/s to 15m/s
6. They generally have low conduction velocity and are polymodal
Explanation:
Axons were know to have different thickness and this differences were thought to relate to the speed at which the action potential could travel. This hypothesis was proved by Erlanger and Gasser.
Answer:
The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.
Explanation:
Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.
As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.
So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.
Hypothalamus. Hypothalamus, besides controlling hunger, also, controls thirst, body temperature, sleep, emotional, physical, instinctive and reproductive behavior. Through pituitary is associated whit endocrine system, which is one of most important functions of hypothalamus.
<span>A polypeptide is a single linear chain of many amino acids, held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty). </span>
