Which of the following is NOT a capillary transport mechanism?
Zanzabum

Answer:

Bulk flow

Explanation:

Generally when there is  mass movements of molecules of the fluids from a high pressure gradients to low pressure gradients; that is down the concentration gradients, the process is called Bulk flow. In relation to cells, it is  the exchange of material between cells  through the pores of the adjoining  cells. In xylem , water and minerals flow from high pressure roots to the leaves, and phloem transport food substances from the  leaves the sources at high pressure to other parts of the plants.

The capillary transport mechanisms involves the movements of fluids, ions across the fenestration of the capillaries due to  the hydostatic  pressure of the fluid from the high pressure to the low pressure cellular environments.This is common in the  glomerulus of the kidney, intestine, and some endocrine glands.

The single wall endothelial lining of  capillaries forms continuous wall which allows passage of ions and fluids while restricting movements of large molecules. Generally the high pressure  from the hydrostatic pressure forces these materials across the walls.

Simple diffusion  which follows concentration  gradient across membranes ensures distribution of substances across the walls for fast uptake by the cells.

The movement of Macromolecules  across capillary wall is called vesicular transport.

Thus Bulk flow is odd.

When a neurotransmitter reaches an excitatory synapse
grigory [225]

Answer:

Sodium ions move into the postsynaptic neuron causing depolarization of the

postsynaptic neuron

Explanation:

That's the mechanism of action potential generation. Neurotransmitter receptors are connected to sodium channels. When those sodium channels open the cell becomes depolarized(the charges reverse), that means the inside of the cell becomes more positive while the outside becomes negative

Explain effects of ecto parasite<br>​
boyakko [2]

Answer:

Ectoparasites may affect trade-offs between life history traits in a number of different ways (Moller 1993a). There is some field evidence which suggests that ectoparasite numbers increase with the advancement of the season (Loye and Carroll 1991).
