Answer:
A marine biologist is more in demand. A marine biologist is a scientist who studies plants and animals that live in the ocean. A marine biologist seeks to understand ecosystems, biology and behaviors while analyzing how different marine species interact with each other. Besides studying how ocean life affects itself, marine biologists may also examine the impact that human interaction has on marine biology. Explanation:
Answer:
168 toads
Explanation:
First we need to find the area of the garden. Area = length x width
Area = 12m x 7m = 84 m²
2 toads/ 1 sq m
84(2) = 168
Answer:
The reservoirs are the atmosphere, the terrestrial biosphere (which usually includes freshwater systems and non-living organic material, such as soil carbon), the oceans (which includes dissolved inorganic carbon and living and non-living marine biota), and the sediments (which includes fossil fuels).

If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
simpler answer: Cells are small because they need to keep a surface area to volume ratio that allows for appropriate intake of nutrients while being able to eliminate the cells waste.
A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.
