Answer:
The correct answer is : surveying.
Explanation:
Paleo-anthropology is the study of the extinct primates, it is a sub branch of anthropology. It is focused on the human evolution and rise of the sub type of family of the other human or hominids.
Surveying is the one of paleoanthropoolgy practices that involves the finding the fossils of hominids on the surface of all around the globe by walking to compare it and study the evolution of human family.
Thus, the correct answer is- surveying.
Answer:
The best answer to the question: These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses, would be: T-Tubules.
Explanation:
In both skeletal and cardiac muscle, not smooth muscle, because of the way that the muscle fibers are conformed into tight bundles of sarcomeres (skeletal muscle) and myocardiocytes (cardiac muscle), there is a need for a series of structures that will ensure that when there is a stimulus from the nervous systems, these stimulus will propagate to all the cells in the fibers, and not just one.
Aside from counting with a neuromuscular motor plate, which will receive the neurotransmitter from the nerve endings and produce the appropriate reactions, as well as propagate that reaction to all the cells that are being stimulated, muscle fibers also have a structure known as T-Tubules. T-Tubules are formations much like roadways of cell plasma membrane that connect not just one, but all the cells within a muscle fiber so that once a stimulus comes, all the cells will initiate the process of calcium release and action potential propagation. These T-Tubules will ensure that electrical impulses reach all muscle cells and that all cells react at the same time as needed.
C. Arachnida.
hope it's correct.
Answer:
300% - 400%
Explanation:
The cardiac reserve is in the range of 300 to 400 percent (300% - 400%
) in normal young adults, while this percentage can be increased to 600% in trained athletes
There cannot be more carnivores than herbivores because the carnivores eat the herbivores. If there wasn't enough herbivores to eat, then the carnivores would eventually become extinct.
