Answer:
Explanation:
A keystone species is the one which plays an important role in maintaining the structure of the ecosystem. On the keystone species many other species of the ecosystem are dependent upon.
The potential effects associated with the keystone species includes the following:
1. No other species will be capable of filling the same ecological niche. Hence, the dependent organisms will suffer and the ecosystem will change drastically.
2. The ecosystem will be populated by the invasive species which will affects the population of native species.
The cell membrane functions as a selective barrier. We call these kind of membranes as differentially permeable or semi permeable membrane. It can decide what substances can pass in and out. Therefore it can surround the cytoplasm (which is the inside of a cell) to separate the cell's content from the surroundings.

Answer:
A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.
Explanation:
Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.
It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.
Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. ... The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.
