polar body
A small relitively hard,naturally formed mineral.

Corries or Cirques are bowl like hollows in a mountain range, formed by the action of a small glacier.
Oxyhaemoglobin is oxygenated blood. Impure blood is carried to the lungs where exchange of gases occurs in the alveoli of the lungs and the blood is purified as it gets oxygenated and becomes oxyhaemoblobin.
Fumaroles are formed only when steam and hot gases are expelled from small vents, usually found on volcanoes.
Polar Body
there are 1001 cell produced in male and females meiosis During meiosis one microspore mother cell in the male results in to four microspores after meiosis; so is the case with megaspore mother cell also in females but out of four megaspores only one is functional and the degerating three megaspores nourish the developing one.
a polar body is A small cell (which eventually disintegrates) that is the by-product of meiosis in female animals. One functional ovum and potentially three polar bodies result from meiosis of each primary oocyte. By:hyden 252-1079 im bored
To ensure the survival of the ovum, materials are taken from daughter cells during oogenesis. Because there are two divisions, there are four daughter cells. But only one cells is the ovum and the other three are not viable and die immediately. Those cells are called polar bodies.
Budding or fission are not part of mitosis or meiosis but these are types of asexual reproduction .During budding in Yeast a small out growth appears on one side of cell , enlarges and separates .During fission one cell divides in two equal cells as in Amoeba .
You need one sperm and one egg to reproduce. An egg fertilizes the egg, inside of a woman. Think of it as two halves to a whole. The woman has fifty percent of the necessary genes in her egg, and the man has the other fifty percent. Mixing one sperm and another can't make a baby, nor can one egg and another.
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.

Meiosis
There is only one interphase, and it's the same as other cells: to grow, function, and replicate DNA. Meiosis is only a small part of cell cycle and interphase is not included in it. There are, however, two different phases in meiosis, such as prophase I and prophase II.
A small, almost microscopic portion section of the sun is shown I think but im not sure
In bryophytes, particularly ferns, meiosis takes place is the stuctures called sorus. These are small dustlike brown dots lining the underside of ferns. The sori contain reproductive cells that produce spores.
