Agriculture just became easier. It was much easier and safer than directly hunting, albeit, it wasn’t always as rewarding, but it was much more reliable. If you could hold off until the large crop was fully grown with hunting, you could rely on the large crop while waiting for the next one, and have a berth large growth. In other words, it was more reliable, easier, and could be very lucrative.
Answer:
The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.
Explanation:
There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.
A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.
A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.
The extinction of snakes from the population will lead to decrease in genetic variation.
Answer:
Hydrogen Bond
Explanation:
Hydrogen bonds allow two molecules to link together temporarily. Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds. The polarity of the water molecule is what gives water its unique properties.
One of the most common and well known atmospheric optics, the rainbow is formed when sunlight is refracted and reflected by water. A collection of droplets in the atmosphere — whether from rain, a waterfall, a sprinkler, etc. — disperses the entire visible light spectrum at an angle, resulting in the circular shape.
