Answer:
C. The bacteria have high genetic variability and high reproductive rates.
Answer: See attached picture.
Explanation:
DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.
The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.
<u>What distinguishes one polynucleotide from another is the nitrogenous base</u>, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.
The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.
The correct order would be:
1. A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis;
2. A caterpillar gets the carbon by eating the tree's leaves.
3. A bird gets the carbon by eating the caterpillar.
4. The bird flies into a building and dies instantly. It falls to the ground.
5. The bird decomposes and the carbon returns to the atmosphere.
The carbon cycle is very similar to the water cycle, though it has its own unique ways. Once the carbon is released into the atmosphere, it will either be absorbed by the vegetation, or go up into the higher parts of the atmosphere. If it is absorbed by the vegetation, the organisms that eat the vegetation will get it in them. When the predators eat those organism they get the carbon into their organisms. When the predators die, they start to decompose. When they decompose, the carbon is released from them and it returns to the atmosphere, and the whole process goes all over again.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.
