Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
What will happen to the number of starch grains in the cell if euglena is kept in the dark?
If chlamydomonas is kept in the dark, the number of starch grains in the cell will reduce
How does scientific notation reduce errors?
Scientific notation may reduce errors by removing the need to count leading 0s in a number smaller than 1 or trailing 0s in numbers larger than 9.However, one common use of scientific numbers is to reduce the number of significant digits. While that simplifies calculations and gives the answer to an appropriate degree of accuracy, it can introduce rounding errors and truncation errors.Scientific notation may reduce errors by removing the need to count leading 0s in a number smaller than 1 or trailing 0s in numbers larger than 9.However, one common use of scientific numbers is to reduce the number of significant digits.

Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
What does a bit of oil reduce in science?
Oil is used to reduce friction.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
Why meiosis and gametogenesis are always interlinked?
Meiosis is the process by which the nuclei of certain somatic cells reduce the number of chromosomes by half, in order to produce gametes, or sex cells. The production of gametes is known as gametogenesis. Gametes must have only half the normal number of chromosomes (a condition known as haploid) so that when two gametes (an egg and a sperm) combine, the resulting zygote (fertilized egg) will have the full number of chromosomes-a condition called diploid.
When and why does meiosis occur?
It occurs to reduce the number of gametes.
What would happen to the chromosomes in each cell if copies of them were not made before cell division?
There would be no life
Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
The net result of meiosis is to reduce the number of chromosomes in gametes to only one from each?
homologous
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)

Polyploid speciation occurs through?
Polyploidy is to have two copies of each chromosome, itâ??s important in crossbreeds to allow reproduction. Polyploidy speciation requires altering a chromosome number; itâ??s more common in plant species.
What is the purpose of miosis?
Both meiosis and mitosis are types of cell divisions. Meiosis occurs in germ cells or reproductive cellswhile mitosis occurs in both reproductive cells and body or somatic cells. The former is called as reduction dision as it results in reduction of total number of chromosomes in the daughter cells, in order to maintain a constant chromosome number thereby race is maintained. The latter is called as multiplication division or replica division as the two daughter cells produced resembles the parent cells. Mitosis occurs in order to favour growth and differentiation of an organism.
Can you reduce a fraction in a division problem?
Yes.
During what phase is the chromosome number reduced from 2n to n?
Homologous chromosomes travel to opposite sides of the cell
