D. it produces male and female sex cells
In meiosis, a cell
splits into four cells, also splitting the chromosome count in half from
the original cell. This is a critical stage for sexual reproduction in
that the cells then match up with other haploid cells produced by
meiosis from another parent to create a new organism. These sex cells
have both male and female chromosomes and the resulting sex depends on
how the cells match up with those of the other parent.

Answer:
Carbon based molecules have 3 main structures which are
straight chain
branched chains
rings
Explanation:
The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.
