i am having a very hard time in science and i dont really understand anything and none of it is my text book
thanks
type of reproduction that requires the joining of two sex cells?
the type of reproduction that produces a new organism; with identical chromosomes to those of the parent organism?
the process that produces haploid sex cells?
what cell forms when an egg and a sperm join?
the sections of DNA that contain instructions for producing specific proteins?
thank you sooo much!!

1. reproduction that requires te joining of two sex cells
sexual reproduction
2. type of reproducuction that produces a new organism with identical chromosomes
asexual reproduction
3. Meiosis forms haploid sex cells. In females, three of the four cells formed become polar bodies. In males, all four haploid cells become sperm cells.
4. When the haploid egg and sperm join, they form a zygote.
5. RNA contain the instructions for producing specific proteins.

Sorry you're confused, and it looks like some of the answerers are confused too!
1. Sexual reproduction (the two cells are egg and sperm and the process of joining them is called fertilization)
2. Asexual reproduction (some examples are cloning, budding, binary fission, and parthenogenesis)
3. Meiosis (the "haploid cells" are the gametes, otherwise known as egg and sperm)
4. A zygote (this is a single cell that results from the egg having the sperm get inside and combine their two DNAs.)
5. Genes (that's the definition of a gene)

type of reproduction that requires the joining of two sex cells?Mitosis
the type of reproduction that produces a new organism; with identical chromosomes to those of the parent organism?
Meosis (I think)
the process that produces haploid sex cells?(dunno)
what cell forms when an egg and a sperm join? (embryo or fetus not sure)
the sections of DNA that contain instructions for producing specific proteins?(Ribo somethin)
Sorry if I couldnt help but check ya textbook. I suppose your in the sixth grade right?

> type of reproduction that requires the joining of two sex cells?
Sexual reproduction

Several answers here.
a) binary fission (for bacteria)
b) mitotic cell division (for single-celled organisms such as protists)
c) vegetative reproduction
> the process that produces haploid sex cells?
Meiosis
> what cell forms when an egg and a sperm join?
zygote
> the sections of DNA that contain instructions for producing specific proteins?
Genes (the answer is a little more complicated than that, because of introns, but "genes" is the answer your teacher wants).

1. sexual reproduction
2.asexual reproduction (via meiosis)
3. meiosis in humans produces 4 haploid cells, mitosis produces two diploid cells genetically identical to the parental cell.
4. diploid cell
5.alleles?? (not sure...)

the formulation for area of a circle is pi(r)squared. so which you do 50.24=pi(r)squared simplify- (50.24/pi) = r squared take the sq. root of the two aspects, and you get the radius. in case you dont have a calculator that has pi, then use 3.141559, its close sufficient. for the diameter, multiply the radius via 2 wish this helps Kareem

All of that is in your textbook. Stop being lazy and do your own homework.
