Answer:
Water can diffuse across a selectively permeable membrane in a process called osmosis. Osmosis in cells is a form of facilitated diffusion. ... But the cell membrane contains channel proteins that only water molecules can pass through. Osmosis allows cells to maintain water balance as their environment changes. it realates to hemeostasis Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy. The cell membrane is a lipid bilayer that prevents the passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
Explanation:
A gas called Ethylene which is given off by the already ripened fruit speeds the process of ripening for the unripened fruit.
Well this has to be your opinion :) but I will tell you autotrophs are organisms that can make their own food, so plants. Heterotrops are organisms that have to get their energy from another source, animals. So would you rather be a plant or animal (like you already are) and why?

Answer;
B. De facto segregation still exists.
Explanation;
De facto segregation is a racial segregation, especially in public schools, that happens, by fact, rather than by legal requirement. For example, often the concentration of African-Americans in certain neighborhoods produces neighborhood schools that are predominantly black, or segregated in fact, and not by law.
Answer:
Since the sperm and egg each contribute 50% of the nuclear genetic material to the zygote that becomes the embryo, mitochondria and plastids that become chloroplasts are passed primarily from the female parent, due to a characteristic of the female gametophyte is be larger and formed from one surviving megaspore (option c).
Explanation:
The megaspore is the product of the meiosis of a megasporangio, the cula produces four structures of which only one is transformed into a megaspore.
The female gametophyte is formed from the megaspore which, being large and having a greater quantity of cytoplasm, contains the mitochondria and plastids that will originate the chloroplasts in the embryo.
