antigen-presenting cells usually display processed antigens to t cells in the _____________.
Antigen-presenting cells usually display processed antigens to T cells in the LYMPH NODES. These nodes are regions of the body where lymphocytes are activated.
T cells are white blood cells (lymphocytes), which form part of the immune system.
These cells (T cells) develop in the bone marrow.
The lymph nodes are secondary lymphoid organs in which naive T cells that search for specific antigens examine antigen-presenting cells (APCs) for their activation.

Explanation:
can solute particles pass through the membrane of a semipermeable membrane?
Answer:
No.
Explanation:
No, solute molecules are larger in comparison to solvents, so they cannot pass through the semi-permeable membrane.
Answer:
Nope Nope Nope, They cannot pass through it
Explanation:
Osmosis describes the diffusion of the solvent through a semipermeable membrane. The driving force of the solvent shift is the concentration difference of solutes in the solutions separated by the semipermeable membrane. In contrast to solvent, solutes cannot pass this barrier.

cells that can differentiate into any cell type in an organism are referred to as ______ cells.
Cells that can differentiate into any cell type in an organism are referred to as pluripotent cells.
What is Pluripotent stem cells?
Pluripotent stem cells are cells that have the ability to self-renew by splitting and growing into the three immediate germ cell layers of the earlier embryo.
Hence into all cells of the grown-up body, but not extra-embryonic tissues such as the placenta.
Thus, pluripotent cells are Cells that can differentiate into any cell type in an organism.

like firecrackers, greenhouse affect etc...
Answer:

Explanation:
bok choy is causing pollution
brainly plz
Answer:
hehe i just finished answer a question about pollution sooo here you go :) this is just an example and not a full essay I recommend adding more evidence!! (please write in your own words)
Pollution has been a problem for over 2,000 years now. There are many things that are causing pollution. For example firecrackers!
Using firecrackers can be very dangerous not just for us, but the environment as well. Firing crackers can increase the concentration of dust and pollutants in the air. After firing, the fine dust particles settle on the surrounding surfaces which are packed with chemicals like copper, zinc, sodium, and lead. Now you may think oh so it's bad for the air so what? If the air is polluted, trees and plants that give us oxygen can't do their job. If they can't do their job we can't breathe or live. Most of the chemicals that are bad for the air are in firecrackers. These chemicals can last for hours or days on end, exposing you and your neighbors to possible long-term health problems. Then fireworks also have the potential of starting wildfires. About 7,500 to 10,600 trees were burnt down (10% to 14% of trees) in California alone due to wildfires. About 19,500 trees were burnt down just from fireworks.
give example on substitutions for frieworks. I would recommend adding more information about how the chemicals in the firecrackers are dangerous for the air. Since I didn't go into full enough details (if you don't you might get marked down for not having enough details or evidence)
