Housing impacted slaves as they were forced to live in small quarters. diseased spread rapidly and the quarters were always dirty. they had no personal space. disease was rampant and there was no cure for them. most slave owners did try to help the slaves because they were valuable property but disease was still an immense problem.
Its is to remove liquid waste from the blood in the form of urine, and keep a stable balance of salts and other substances in the blood and produce erythropoietin, hormone that is the formation of ref blood cells. The kidney remove ursa from the blood through this filtering units called nephrons
Stomata open in the daytime, when there is an abundance of heat energy from the sun that causes evaporation of water, causing the guard cells to become flaccid, allowing the stomata to open.
<h2>Functions of plasmodesmata</h2>
Explanation:
- They allow the movement of cells to cells for cytoplasmic connection between different cells
- Plant cells, encompassed as they are by cell dividers, don't get in touch with each other through wide stretches of plasma film the manner in which creature cells can. Be that as it may, they do have particular intersections called plasmodesmata (solitary, plasmodesma), places where a gap is punched in the phone divider to permit direct cytoplasmic trade between two cells.
- Plasmodesmata are fixed with plasma film that is consistent with the layers of the two cells. Each plasmodesma has a string of cytoplasm stretching out through it, containing a much more slender string of endoplasmic reticulum.
- Particles beneath a specific size (the size rejection limit) move unreservedly through the plasmodesmal channel by latent dissemination. The size avoidance limit changes among plants, and even among cell types inside a plant. Plasmodesmata may specifically enlarge (extend) to permit the section of certain huge atoms, for example, proteins, in spite of the fact that this procedure is inadequately comprehended.
