How can an organism's environment affect its traits?

Answers

First, I read that so incorrectly. Awkward.

An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.

How do moving glaciers change the surface of the earth??? please help!!!​

Answers

Answer:

Glaciers are massive bodies of ice that move across the surface of the Earth like rivers. As glaciers move they change the surface of the Earth by wearing away loose rocks and soil and depositing them somewhere else.

Explanation:

Answer:

Glaciers change the surface of the earth by causing small or large amounts of material to be pushed out of the way as the glacier slides along a path set by gravity and angle of the slope it is on.

C. It is more than 2.1 million years old.
D. It is exactly 1.4 million years old.

Answers

Answer:

B

Explanation:

It is less than 1.4 million years old

Based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

What do you mean by Fossils?

Fossils may be defined as the dead and organic remains of the past organisms which are preserved deep in the soil over a long period ago.

The fossil found in area A is very recent from the evolution point of view. The deeper the layer, the oldest is the fossil.

Area A of the fossil is synthesized after the time period of 1.4 million years ago, hence the fossil present in that area would be less than 1.4 million years old.

Therefore, based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

What part of meiosis is responsible for variation?

Answers

Answer:

the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Answer:

The two events that set meiosis apart from mitosis are known as crossing over (or genetic recombination) and independent assortment. These occur in prophase and metaphase of meiosis

During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Explanation:

Genetic variation is increased by meiosis

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I
