Meiosis l
Which type(s) of cell division can be classified as reductional?
Meiosis I
Which type(s) of cell division can be classified as equational?
Mitosis and Meiosis II
Explanation:
Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II. The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.
Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.

Explanation:
<span>The sunspots are eruptions of heat and light energy emitting from the surface of the sun. These can increase our energy absorption many times above normal. Especially if it is pointed directly at the earth. These have been known to disrupt several bands in the radio spectrum and have knocked out communications of satellites. Naturally all this energy would have a great effect on our earth in many ways, climate included.</span>
The nitrogenous bases (guanine,cytosine,thymine,adenine) code for our traits.
