In which position are the earth, moon, and sun during a new moon?
dimaraw [331]

Answer:

A. Moon is between the Sun and Earth

Explanation:

The new moon stage is the faze in which we can not see the Moon from Earth. In this stage, the Moon is lacking from the sky, or rather we can not see it because it is totally dark from the side that is facing the Earth. The reason for this is that the Moon is located between the Sun and the Earth. The Sun is making half of the Moon bright as it always does, but in this stage it is the half of the Moon that is facing the Sun, while the other half that is facing the Earth is totally dark as it doesn't receive any sunlight at that time.

Each biological species is genetically isolated from other species. why do the species evolve independently?
Nookie1986 [14]
Species evolve independently possibly due to geographical isolations or behavioural isolations.

Geographical isolation includes the isolation of 2 groups of the same species. Since these 2 groups live in different locations, (e.g. a volcanic eruption resulting in a barrier between one side of an ocean and another side of the ocean), they will have different selection pressures in their different environments as well (e.g. one side of the ocean may have more sunlight and thus more underwater plantations than the other side of the ocean). Natural selection will eliminate those with disadvantageous characteristics (e.g. Fishes that only eat plants and nothing else on the side of the ocean with little plantations) with unfavourable alleles, and select for those with advantageous characteristics (e.g. Fishes are able to eat plants and other organic substances as well on the side of the ocean with little plantations) with favourable alleles.

Since the 2 groups have different selection pressures, natural selection will occur in different ways, selecting for and against different types of fishes with different types of alleles. Also, because of the barrier, they are not able to mate with each other, and there are no mixing of genes from one side of the ocean and the other side. They are genetically isolated. As genetic drift occurs over time, their gene pools become different from each other. Thus, they evolve independently.

Hope this helps! :)
