Answer:
(A) The variation resulting from meiosis and the union of gametes means some individuals will have a chance of colonizing diverse distant environments successfully.
(D) Vegetative propagation is more efficient than sexual reproduction when the current generation is well adapted to the local environment.
Explanation:
Sexual or asexual (options B and C) are not a "last ditch", it pretty much depends on the type of organism and its strategy for survival. There are thousands of organisms that can reproduce either sexually or asexually depending on the environmental conditions.
Option A. Genetic variability is important because sometimes the genetic variability produce during the sexual reproduction processes (crossing over, chromosomes assortment and DNA from 2 parents) can confer an organism the adaptability mechanism to thrive in different environments.
Option D. Since asexual reproduction delivers genetical equal organisms, the offspring is already adapted to local conditions and can colonize at a faster rate.
The Krebs cycle can be used to make many various intermediates that can be siphoned off into other pathways. Mainly though, it makes the electron carriers NADH and FADH2 which can then be used in the electron transport chain to generate ATP.
Toxic waste occasionally leaks to nearby ponds. That is option 1.
<h3>Wastes from mining</h3>
Mining is a process used by geologist to extract valuable minerals that are naturally deposited within the earth.
Example of such minerals are:
- rock salt, potash, gravel, and clay.
While mining processes are carried out, it leads to the generation of waste products such as:
- ferrous and nonferrous metal ores,
- apatite-nepheline concentrates,
- coal wastes and halite flotation wastes.
These mining wastes can leak into the nearby ponds after a heavy down pour leading to the contamination of the ponds.

Answer:
La palabra célula viene del latín cellula (pequeña celda) formada de cella (celda) y el sufijo diminutivo -ula, que encontramos en palabras como cápsula, molécula, vernácula. La palabra latina cella viene de una raíz indoeuropea *kel- (cubrir, esconder), que encontramos en las palabras ocultar, célula y color.

Explanation:
A bird with blue-tipped feathers (genotype Bb), when crossed with a white bird (genotype bb) can produce offspring with genotypes according to the following Punnett square:
![\begin{array}{ccc}\ \ \ &\ B&b\\\end{array}\\\begin{array}{c}b\\b\\\end{array}\left[\begin{array}{cc}bB&bb\\Bb&bb\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccc%7D%5C%20%5C%20%5C%20%26%5C%20B%26b%5C%5C%5Cend%7Barray%7D%5C%5C%5Cbegin%7Barray%7D%7Bc%7Db%5C%5Cb%5C%5C%5Cend%7Barray%7D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DbB%26bb%5C%5CBb%26bb%5C%5C%5Cend%7Barray%7D%5Cright%5D)
In other to have entirely blue feathers, an offspring would have to have the BB genotype. Since it is not possible to obtain this genotype by crossing the birds in question, the percent chance that an offspring will have entirely blue feathers is 0%.
