Answer:
One beneficial result of a cell having a larger surface area is its ability to cover more area increasing the likely hood of nutrients coming in contact with the cell membrane. Which in turn will increase the rate at which nutrients diffuse through the cell membrane.
Answer:
Lower liver border.
Explanation:
The liver is in the upper right side of the abdomen, above it is the diaphragm, beneath is the right kidney, the stomach, and the intestine. If we position our hands on the right clavicular line and bellow the umbilicus, as we move them, we will be able to locate the liber when we arrive at the upper right side of the abdomen and feel if there is any problem.
The question is incomplete as it does not have the option which are:
-acid-fast
-DAPI
-lipo
-Gram
Answer:
Acid-fast staining
Explanation:
Acid-fast staining is the technique used to stain and identify the species of the mycobacterium.
During the acid-fast staining, the carbolfuchsin stain is used to color the bacteria as carbolfuchsin solubilizes the lipid of the bacterial wall and the pink stain enters the cell. When these cells are treated with the methylene blue counterstain, the mycobacterium due to the presence of thick cell wall does not allow the entry of the methylene blue as a result of which they appear red o pink.
Thus, acid-fast staining is correct.
Answer: Natural selection is the driving force to explain the mechanisms of evolution.
Explanation:
◼In a given population Organisms usually produce more offspring than what the environment can support.
◼ VARIATION, is driving force for the manifestation of sustainable inheritable characteristics from parents in a given population.
◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.
◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.
◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.
This is survival of the fittest by natural selection
, this is the second conclusion of Darwin theory.
