PLEASE CHECK MY ANSWER!!!!!!What is the result at the end of meiosis II?

A.
two haploid cells

B.
four haploid cells

C.
two diploid cells

D.
four diploid cells

I think it's B.

Answers

The answer is B. four haploid cells. In the meiosis, the number of chromosomes is reduced by half. It consists of meiosis I and II. In meiosis I, 2 haploid cells are formed from a diploid mother cell. These 2 haploid cells undergo meiosis II which is similar to mitosis. As the result of meiosis II, 2 haploid cells form from each haploid mother cell. Therefore, as the result of meiosis, 4 haploid cells are formed.

What is trait ?

Traits are the attributes of an organism which are influenced by the environment and expressed by genes, the Physical features of an organism, such as hair color, leaf form, size, behavioral characteristics,

Species with substantial variation in traits For example, white-tailed deer in Pennsylvania have seed coat color with limited variation, all the organism have characteristics are genetic traits or behavioral traits.

Genetic Traits can be defined as the genes that one gets from both parents influence, the Individual and independent traits are defined by genes, which are encoded by unique portions of our DNA.

What effect does temperature have on the characteristics of magma

Answers

Magma, like many other things, liquifies at high heat and it cools down and solidifies at low temperatures. Basically, while inside a volcano, magma is liquid and extremely hot and flows freely. When it bursts out, it becomes lava and starts cooling down due to the air and winds and things like that, so it starts turning into rocks and in time these rocks create new layers of the volcano. This is how many islands were formed.

As temperature increases the viscosity of magma decreases,so the magma flows more easily.
