Determine which type of transport is being depicted below
irinina [24]

Answer:

Active transport

Explanation:

The molecules are moving from a low concentration to a high concentration across a cell membrane via a protein. ATP is used in this reaction.

We know it cannot be diffusion, facilitated diffusion, passive transport, or osmosis, because these are all passive processes. In the picture, the molecules are moving against their concentration gradient and uses energy.

It cannot be endocytosis or exocytosis, as there are no vesicles.

Active transport is the movement of molecules from a low concentration to a high concentration across a cell membrane against their concentration gradient. ATP is used to supply the energy for this process.

Describe how lymph nodes and organs help the immune system fight pathogens.
I am Lyosha [343]

The defense system of the human body is made up of entire organs and vessel systems like the lymph vessels, but also of individual cells and proteins. The inner and outer surfaces of the body are the first barriers against pathogens (germs). These surfaces include the skin and all mucous membranes, which form a kind of mechanical protective wall.

Several things support this protective wall:

<span><span>- The body’s own antibacterial substances can disable different pathogens from the environment at an early stage. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
</span><span>
- Many pathogens that are breathed in get stuck to mucus in the bronchi and are then moved out of the airways by hair-like structures called cilia.
</span><span>
- Most pathogens that enter the body together with food are usually stopped by stomach acid.
</span><span>
- Normal flora, harmless bacteria that reside on the skin and many mucous membranes in the body, also help to protect the body.</span></span>

The cough and sneeze reflex can also help to remove pathogens.


Hope this helps (:

- what are two reasons why the height of clouds vary from day to day?
maksim [4K]

Some clouds form as air warms up near the Earth's surface and rises. ... That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense.
