Answer:
Option B, both evolutionary history and their own individual life histories.
Explanation:
Physical anthropologists study about both the evolutionary background of an individual as well as the environmental stresses faced by him/her. They believe the identity of an individual is affected by the following – family background (genetic history), culture is which he/she has been brought up, and also the societal elements. Due to this reason Physical anthropologists focus on different areas such as forensic, skeletal biology, Primatology, human biology etc.
Hence, option B is correct
Answer:
Cytochrome iv allow the transfer of electron from cytochrome a₃ present in cytochrome iv that reduce oxygen on mitochondrial membrane for ATP synthesis.
Hypothesis: cyanide blocks the cytochrome iv, therefore, oxygen will not be utilized which is important to derive energy for the cell to live.
So binding of cyanide inhibit the electron transfer to the oxygen atom, therefore, the electron transport chain will be blocked at the terminal position. This blockage does not allow the use of oxygen atom to derive energy for the cell and result in the rapid death of the cell.
So cyanide poisoning in humans is fatal because it blocks ETC by restricting the transfer of electron from cyt iv to oxygen and ultimately blocks ATP synthesis which is required by the cell to live.
No production of ATP or energy for itself since the mitochondria is involved in making ATP
Answer:
Grey matter contains numerous cell bodies and relatively few myelinated axons while white matter contains relatively few cell bodies and is composed of chiefly long-range myelinated axons.
