Answer:
<em><u>ribosomes</u></em>
Explanation:
Ribosomes can be described as large biomolecular complexes that are composed of RNA (particularly ribosomal RNA) and proteins.
They act as site for the synthesis of protien in both prokaryotes as well as eukaryotes.
mRNA (messenger RNA) arrives at ribosome after it gets transcribed from DNA.
mRNA gets converted to particular protein (through assembly of amino acids that are carried by specific tRNA molecules according to codons in the mRNA) that is needed by the cell.
This process is known as translation and it takes place at the site called ribosome.

Answer:
Telomerase acts to elongate the 3' end of linear DNAs.
Explanation:
The 5' ends of the linear DNA can not be replicated by DNA polymerase due to the absence of free 3' end to be elongated. This is prevented by the action of telomerase enzyme which contains both RNA and protein components. The RNA component of the telomerase is 150 nucleotides long.
The telomerase enzyme elongates the 3' end of the template strand by using its inbuilt RNA template. Since it uses an RNA template to make the DNA copies, it is a reverse transcriptase. Repeated translocation and repositioning of the enzyme elongates the 3' end of the template DNA.
The RNA primase makes the RNA primer at the end of the new telomere strand which is then elongated by DNA polymerase. DNA ligase seals the nick. In this way, telomerase serves to prevent the loss of 5' ends of linear DNA in successive rounds of DNA replication.
It's the pull of gravity on an object.

Answer:
A. A pairs with U
Explanation:
In DNA, the nitrogenous bases are A, T, G, and C. In RNA, the nitrogenous bases are A, U, G, and C.
A pairs with U in RNA because it requires less energy to use uracil over thymine.

These mammals use glucose and oxygen in order to perform aerobic cellular respiration to make usable energy. This energy allows their cells, tissue, organs, hence whole body function properly.
