Flow of individuals in and out of a population introduces new alleles and increase genetic variation within that population. Mutations: changes to an organisms DNA that create diversity within a population by introducing new alleles.
Because people throws trash into rivers and stuff and they flow down into the ocean and makes it unclean
Answer;
A Both make it possible for the conditions in the interior to be different from the conditions outside.
Explanation;
Groups of molecules called microspheres may have preceded the living cells of today. Microspheres are tiny bubbles filled with groups of large organic molecules; they can form under very specific conditions. These microspheres may be a lot like the vesicles formed from the organic compounds taken off of the modern meteorites. Microspheres are not cells, but they do share some characteristics with cells.
These bundles of molecules are able to maintain an internal environment different from the surroundings outside the bubble. They also have a simple way of storing and releasing energy. They expand by absorbing additional molecules until they reach an unstable size, and then they split into smaller microspheres. This division is not true reproduction or cell division, but it may be a precursor to it.
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct :)
Answer:
B. Translation can begin while transcription is still in progress.
