Answer:
Pinocytosis can be recognized when the CELL IS ENGULFING EXTRACELLULAR FLUID
Explanation:
Pinocytosis is the process whereby the cell takes in macromolecules such as bacteria and antigens in form of fluid from the extracellular fluid.
The macromolecules in the form of droplets of fluid bind to the outer surface of the cell
The cell membrane enviginates around the droplets of fluid and are engulfed by the cell.
They form vacuoles with the macromolecules and are transported into the inner of the cell.
The formed structure is called ENDOSOMES which lysozomes combine with and form secondary endosomes containing enzymes to break down the macromolecules.
Pinocytosis is also called CELL DRINKING.
Answer:
Sympathetic Nervous System.
Explanation:
Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.
As a whole the autonomic nervous system controls the unconscious responses of our body.
The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.
I would say B.) very fast growth and development.
I believe it is Covalent?
Ecological pyramids are drawn where predators are above prey and they show the population number of each organism shown. Therefore, as the pyramid rises, the population number of the organism decreases, ultimately resulting in a roughly pyramidal shape. Since, organisms higher up the food chain tend to be less numerous than those at the preceding trophic levels, the pyramid is often the classic pyramidal shape. The difference in numbers of organisms at different levels can be so great that logarithmic scales have to be used.
