Answer/Explanation:
DNA and messenger RNA (mRNA) are different in a variety of ways that impact their function in the cell. One way in which they are different is their location. DNA is found in the nucleus of the cell, whereas mRNA is produced in the nucleus, but moves to the cytoplasm.
They are also different in terms of their structure. The mRNA molecule is single-stranded, whereas DNA is double stranded, forming a helix. Their composition is also slightly different, DNA uses the nucleotides adenine, thymine, cytosine and guanine, whereas RNA uses uracil in place of thymine.
Finally, they differ in their function. The function of DNA is to hold the genetic information and transmit it to future generations. The function of mRNA is to transcribe the information encoded in DNA and pass it to the protein synthesis machinery, where mRNA is translated to proteins.

Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
Answer:
Through the use of The Endangered Species Act (1973). Alsom national parks are federal, not state land; therefore, the national government can control them.
