By using a standardized approach in their investigations, scientists can feel ... Or they can ignore data that does not support the hypothesis.
Explanation:
BE CAREFUL. Here we ask about the nucleolus precisely and not about the nucleus in general, the precise role of the nucleolus is to assemble the ribosomal RNA and the ribosomal proteins to form the ribosomes. So the answer is B.
In cell biology, the nucleolus is the largest nucleus subcompartment of eukaryotic cells. This particular space of the nucleus is not delimited by a membrane, nevertheless some authors consider it as an organelle and others do not. The number of nucleoli can vary during the cell cycle (usually only 1 in G0 phase).
The nucleolus is composed of proteins, DNA and RNA and is formed around particular chromosomal regions called NOR (Nucleolar Organizing Regions).
It is in particular the place where the transcription of the ribosomal RNAs (5.8S, 18S and 28S rRNA), the processing of these ribosomal RNAs from precursors and the first part of the assembly of the two ribosome subunits takes place. with the association of certain ribosomal proteins. The end of the ribosome assembly occurs in the cytoplasm on mRNA after export of pre-ribosomes through the nuclear pore.
The answer is breathing. This is what I got from my homework paragraph. <span>In breathing, oxygen and carbon dioxide are exchanged with the external environment but there is not a gain of energy and a chemical reaction does not occur. </span>
Answer:
C. 275 nm
Explanation:
At 275 nm of ultraviolet wavelengths causes mutation in a skin cell because at 275 nm of wavelength, maximum DNA Copying Errors occur in the cells that leads to mutation in the cell. A mutation is a kind of change that occurs in the DNA, due to two reasons, due to mistakes that is occur when the DNA is copied or as the result of environmental factors such as ultraviolet radiations.
