Answer:
V≈904.78cm³
Explanation:
The volume of a sphere with a diameter of 12 centimeters is 904.78cm³.
Formulas: V=4/3πr³ and d=2r
V=1/6πd³=1/6·π·12³≈904.77868cm³
Answer:
E. have a variable region that binds to a specific antigenic determinant.
Answer: All members of Animalia are multicellular, and all are heterotrophs (that is, they rely directly or indirectly on other organisms for their nourishment). Most ingest food and digest it in an internal cavity. Animal cells lack the rigid cell walls that characterize plant cells.
Answer:
Undergrowth of water plants hypoxia
Low levels of oxygen.
Explanation:
Eutrophication occur when lake or river has adequate nutrients that will encourage the growth of water plants i.e algae which lead to the depletion of dissolved oxygen in the lake. The growth of algae is increased due to availability of carbondioxide or phosphorus or nutrients required for photosynthesis. This result in tainted drinking water,hypoxia and degradation of recreational activities.
