The impact craters on the moon are created by collisions made by other asteroids many thousands of years ago
Answer:
B. Many members of a key species, and the ecosystem will no longer be stable.
Explanation:
An ecosystem that contains a high degree of biodiversity will have numerous organisms of different species. According to the question, sharks are stated to feed on a wide variety of prey. This means that sharks can feed on any other species of organisms at lower trophic levels.
In a situation whereby an ecosystem contains a low degree of biodiversity i.e. low variety of species, the sharks will have to consume a large numbers of a key species, which will cause the ecosystem to lose stability.
Answer:
The answer will be there will be a constant maintenance of the reliance to 100%
Explanation:
This is mainly because the paradigm is shifting for the bears and not the scientist where the consumption ratio will be balanced to the same on a daily basis ad therefore the percentages will remain constant without any kind of changes to it.

Answer:
<h2>EGFR will activate other proteins without dimerization, causing uncontrolled cell growth.</h2>
Explanation:
EGFR gene
:
Epidermal growth factor receptor,
-which spans the cell membrane so that one end of the protein remains inside the cell and the other end located outer surface of the cell. This causes receptor to attach ligands, and to receive signals ,by which cell respond to its environment. Epidermal growth factor receptor binds to many different type of receptors. The binding of a ligand to receptor allows the receptor to attach to another nearby epidermal growth factor receptor protein (dimerize), activating the receptor complex. As a result, signaling pathways within the cell are triggered that promote cell growth and division and cell survival. If there is abnormlty in the expression of EGFR gene , then the cell show uncontrolled growth.
