Males have two different sex chromosomes, X and Y. Each sperm only carries half the amount of chromosomes of normal (non-sex) cells. This is so that when sperm and egg combine, the new organism has the correct number of chromosomes, half from each parent.
So each sperm will carry 22 autosomes (non-sex chromosomes) and either an X or Y chromosome - because this is half the male's genetic information.
Number of chromosomes is reduced to one half in gametes so that when gametes fuse to form zygote original diploid number is restored .
No two people in the world are exactly the same except identical twins. Their chromosomes are exactly the same because the egg split in two and formed two identical embryos.
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.

You would add the characteristics of the original reference frame itself. For example, if you know the walking speed of a man on a bus with respect to the bus and you want to know the velocity of the man with respect to the ground, find the vector sum of the man's velocity w.r.t. the bus and the bus' velocity w.r.t. the ground. If one reference frame is not a subset of the other, solve first for a reference frame they have in common. For example, if you want to know the velocity of the man in the first example with respect to a passing truck, find his velocity with respect to the ground first. Keep in mind that "forward" can mean different directions in different reference frames.

Isogamy = It means union of gametes that are identical in all respect ; so much so that it is not possible to label them as 'male ' and 'female ' gamete '. Heterogamy or Anisogamy=this case the two uniting gametes are different from each other some how and therefore can labeled as male and female. Oogamy == In this case the two uniting gametes are distinctingly dissimilar and easy to spot as such.
Mitosis produces two Diploid Cells while Meiosis produces four haploid cells. The purpose of Mitosis produces new body cells and does not allow for genetic variation, while meiosis allows genetic variation through multiple processes. Meiosis produces sex cells (sperm) , which are key in reproduction of multi-cellular organisms. Each new cell contains half of the number of chromosomes. Meiosis has 2 cellular divisions, while mitosis only has one. They are both necessary to support life, and they both produce Diploid cells in the first division. Also, from a similar topic in Yahoo Answers (Which has a much better explanation) : Mitosis is a type of cell division to produce 2 X genetically identical diploid (2n) cells for growth and repair. Mitosis occcurs in somatic cells (normal body cells. Prior to mitotic division DNA is replicated to produce two identical chromatids attached by a centromere. This is essential so that each new daughter cell formed receives one copy of each chromosome. (One division) Meiosis only occurs in the sex organs to produce 4 X haploid (n), genetically different, gametes for sexual reproduction. Meiosis consists of two divisions: Meiosis I halves the number of chromosomes to give 2 X haploid cells. Meiosis II doubles the number of cells to give 4 X haploid gametes. Two processes during meiosis I increase variation . In prophase I homomolgous chromosomes cross over at points called chiasmata and exchange genetic material. In metaphase I the chromosomes line up along the equator in pairs. This is called random assortment where maternal and paternal chromosomes are arranged at random. Both of these increase variation to produce four genetically different gametes at the end of meiosis II DNA replication only occurs once, before Meoisis I.
different types of respect describe fundamentally different relationships and therefore different they have boundary expectations associated with them. The three types of respect are; the Respect of Personhood, the Respect of Authority and the Respect of Honor
the female egg and male sperm.
because all different culture have different background and values that we need to respect

The crossing over makes more room for variability. When the chromosomes swap traits, they create different combinations of traits. The different combinations causes more variations in the products.
how do you show respect for the religious practices of different religious sect
No two people in the world are exactly the same except identical twins. Their chromosomes are exactly the same because the egg split in two and formed two identical embryos.
There are many different ways that the Japanese show respect. Their entire culture is based on respect.
Well there is respect earned by fear. Respect earned by people knowing you have knowldege. Respect earned by people who look up to you. Respect earned by people who believe you have great power
