The correct answer is rheumatism.
<span>Rheumatism refers to all the conditions that cause chronic pain affecting the joints and/or connective tissue. It is not the term that describes any specific disorder, but it covers many different conditions such as capsulitis, back pain, neck pain, osteoarthritis. The study of this disorders is called rheumatology.</span>
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.
No somethings only have one cell. they are called unicellular organisms.
Answer:
The decomposer has recycled the organic materials in the leaf and released them back into the soil.
Explanation:
Decomposers are the heterotrophic microbes that derive their nutrition by digesting the dead organic matter present in the dead bodies of living beings such as fallen leaves. As a leaf falls from a plant on the land, decomposers present in the soil start its digestion.
The organic and inorganic nutrients present in the leaves are digested into the simpler substances which in turn are released back into the soil. Therefore, decomposers serve in nutrient cycling by releasing substances such as carbon, nitrogen, phosphorus, and sulfur from the dead bodies of living beings back into nature to allow their reuse.
