If she ran 200 m east then 100 m back then she ran 300 m but only traveled 100 from her starting point.
Facilitated diffusion is the term
given for passive transport of molecules or ions across a biological membrane, facilitated
by transport proteins. The molecules or ions move down a concentration
gradient; therefore, no chemical energy is required and no ATP hydrolysis is
needed. The transport proteins may be responsible for carrying larger molecules
across the membrane by changing their conformation, or water-soluble transport
proteins may carry non-polar molecules with poor water solubility across. Since
no energy is involved in the diffusion, options a) and c) are incorrect. Since
the molecules being carried are not altered in any way, option d) is incorrect.
Option b) ‘transport proteins provide a hydrophilic route for the solute to
cross the membrane’ is correct as water-soluble carrier proteins are able to facilitate
the diffusion of non-polar molecules with poor water solubility.
Answer:
"The immune system is made up of special organs, cells and chemicals that fight infection (microbes). The main parts of the immune system are: white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow."
Explanation:
Well I would ensure there are cleaning supplies like a broom, mop, etc in case something spills and to keep the place clean. You don’t want a dirty salon, that would lead to big health issues like getting rats and roaches lol. I would also make sure I have a fire extinguisher or something like that for safety reasons like a fire. Lastly I think I would have first aid kits or some sort of call list/phone in case of emergency
