<span>T he type of selection that favored progressively larger brain size in human evolution is
</span>directional selection. Directional selection is a type of natural selection (besides stabilizing selection, disruptive selection, kin selection,..)<span> in which an extreme phenotype is favored over other phenotypes. Because progressively larger brain size is an extreme phenotype this is a directional selection.</span>
The water will move out of the fish by osmosis due to existence of concentration gradient .
1 molecule of glucose and 2 ATPs
The correct answer is - phototrophs.
Some of the autotrophs are able to convert the electromagnetic energy from the sunlight into chemical energy in the form of reduced carbon (C). The autotrophs that are able to perform this are called phototrophs. The green plants and the algae are the most prominent members of the phototroph autotrophs.
In essence, the autotrophs are producers, meaning that they are able to produce their own food. The phototrophs are the part of the autotrophs that are able to use the sunlight to produce small amounts of ATP as well as the energy carrier NADHP. By producing the ATP and the NADHP the phototrophs manage to produce glucose, or rather sugars, which are actually their food.
Industrial pollution is density-independent
habitat is density-dependent
food is also density-dependent because its availability varies depending on this factor
a hurricane is abiotic and density-independent
number of mates is density-dependent and hunting by humans is density-independent
