Every doctor you meet should know your family history with health anyway just incase if something were to happened they'll already know. and if heart disease runs in Simon's family there's probably a 50/50 chance he might likely have it too depending so D would be the answer
Mitosis is the division of the nucleolus and other vital organs found within the cell. Cytokinesis calls for the replication of DNA which is necessary before cell division can occur. In plant cells, the large central vacuole (not found in animal cells) must be evenly divided, which also occurs during mitosis. This process does not occur in animal cells, and instead lysosomes (only found in animal cells) must be evenly distributed among the two sister cells. So to summarize, the differences are related to the different organs found in plant and animal cells. Otherwise, everything else occurs as normal!
Answer:
<u><em>C.)</em></u> <em>Crest to trough</em>
Rats account for a decent amount of biomass globally. They are intermediate predators, eating a lot but also being eaten. If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination. Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction. Rats' predators would also suffer if they went extinct. The primary predators are birds of prey, such as hawks and owls. However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats. For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.
The answer is option B "declining number and variety of the species in an area." Biodiversity is a variety of life for example a ecosystem has many species which makes it a biodiversity. Now a loss of a biodiversity would be loosing a huge amount of species in that area or ecosystem which would mean the answer is option B.
Hope this helps.
