<span>As explained above, a cell which has yet to commit to meiosis is diploid. That is, it has 2n chromosomes. When it commits to meiosis, it doubles its DNA, becoming 4n. Then it goes through two rounds of cell division: during meiosis I, it divides into two cells and each of these cells is 2n. Then, during meiosis II, each of the two daughter cells divide again, producing a total of 4 haploid (that is, 1n) gametes So it would be A. Meiosis 1 hope i helped</span>
The correct answer is option 
.
The is an ion made up of two atoms nitrogen and hydrogen.
The polyatomic ions are those ions, which are formed by the binding of the two or more elements, which has a charge and act as an ion. As all others are formed by a single atom, they are not polyatomic, only is formed by two atoms, hence, it is an polyatomic ion.
The role of ATP in the cell is <span>transport energy.</span>
The second one! Fungi do not make their own food.
Mold and Mushrooms are fungi, right? And you see them on old logs, food, animals.. Thats where they get their food from!
Good Luck!
Answer:
External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization can then take place.External fertilization is most common in amphibians and fish.
Explanation:
Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction.
Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either outside the bodies or inside the female.There are two types of fertilization in sexual reproduction. Internal fertilization and external fertilization.External fertilization is a common and widespread in aquatic environments where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization takes place. Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time. The spawning may be triggered by environmental signals, such as water temperature or the length of daylight. Nearly all fish spawn, as do crustaceans (such as crabs and shrimp), mollusks (such as oysters), squid, and echinoderms (such as sea urchins and sea cucumbers). Frogs, corals, mayflies, and mosquitoes also spawn
