Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food.
Answer:
The tail and the caudal fin are the chief locomotory organs of fish and are used for rapid swimming during which tail is lashed from side to side by "alternate contraction and relaxation" of the myomeres on the two sides of the vertebral column.
Explanation:
Answer:
C. Scavenging of dead animals and gathering of plants (just as Homo <em>habilis</em> had done), and perhaps the hunting of smaller animals
Explanation:
Homo <em>erectus</em> (erect man): Homo erectus is believed to be appeared about 1.5 million years ago. It was in the middle Pleistocene age when they evolved from homo habilis. Homo erectus probably ate meat, was around 1.5-1.8 meters tall and males were probably larger than females. As the name suggests they has erect posture. His skull was flatter than that of modern man and he had protruding jaws. Other features includes projecting brow ridges, small canines and large molar teeth. Their cranial capacity was 900 cc. Cranium was dome shaped to accommodate the large brain. Homo erectus was omnivorous and he made various tools using stones and bones. He made use of fire for hunting, defense and cooking. Homo erectus inculdes three fossils: Java Ape-man, Peking man and Heidelberg man.

Explanation:
Let's say I'm feeling like someone named....Elijah... Well I go to bed that night and have dreams that I am Elijah talking to myself.
Answer: a. action potential frequency is high enough that no relaxation of muscle fibers occurs.
Explanation:
A tetanic contraction occurs due to repeated stimuli at short intervals. In this situation, the muscle fiber does nor relax and contracts again. It is a process of sustained contraction of muscles, which evoke when the motor nerve innervates a skeletal muscle and emits the action potential at high rate. The muscles become hyperactive in this condition.
