Answer:
The pairing of the nitrogen bases in a DNA molecule is AT and CG. Let's say that the DNA strand has the sequence of ATCG. The complementary strand of that DNA strand will be TAGC. A and T & C and G must pair with each other. The replicated strand will be the same as the original strand because the complementary strand of the replicated strand will be ATCG, which is the same as the original strand.

Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
In my opinion, it always depends on the partner how they are going to maintain their healthy relationship.

Ribosomes are small particles of RNA and protein which are found throughout the cytoplasm in all cells; they produce proteins by following coded instructions from DNA. They produce proteins through coded instructions that come from the nucleus of a cell.
Answer: air, water, food
, a place to live
Explanation:
The living beings are composed of multiple cells, blood and water. They require certain necessities to survive and reproduce. The air is necessary for respiration. Water is necessary for fulfilling the thirst and maintaining the balance of fluid in the body. Food is necessary as it provides energy to do various biological functions. A place to live is necessary as it is the place where the living being rests, eat food and does other important activities.
