The Nucleus of a neuron is an oval shaped membrane-bound structure found in the soma or body of the neuron. It contains the nucleolus and chromosomes, necessary for the coded production of proteins within the cell. The nucleolus of the nucleus produces ribosomes. The genetic information of an organism is coded within the long strands of deoxyribonucleic acid (DNA) from which the chromosomes are made. DNA is composed of two long chains that are interconnected in a helical arrangement. The sub units of a chromosome (genes) when activated induce the production of messenger ribonucleic acid (mRNA). mRNA is a duplicate of the information contained in the gene. mRNA leaves the nucleus and attaches to a ribosome, where is serves as a template for the production of a protein molecule
Parts of a neuron
Neurons vary in size, shape, and structure depending on their role and location. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites.
1. Cell body
2. Axon
3. Dendrites
Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. Dendrites or nerve endings.
Answer:
Adipose tissue
Explanation:
term for loose connective tissue/ main role is storing energy in a form of fat
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.
Viral infection by consuming animal diet is very common these days. These generally cause global pandemic. Most of the pandemic virus are influenza virus, which causes flu like symptoms in humans as well animals including birds, and poultry animals.
The H1N1 virus, which a Influenza A virus causes many type of infections, which includes Swine flu, Cat flu etc. The cat flu is a flu, which is known to be caused by eating cats. The viruses are well known to evolve and mutate easily and cause the changes in the subtype. The mutations in subtypes of viruses makes it difficult to make a vaccine for these types of flu.
Hence, the first blank can be filled with Subtypes, second blank can be filled with Influenza A and the third blank can be filled with Cat Flu.
Answer:
Solution 2: Businesses switch to other types of vegetable oils that do not cause deforestation. For example, plants, such as corn and sunflowers, are grown in a grassland ecosystem.
Explanation:
The second solution suggested will create a win-win palliative for the locals and the forest they are cutting down.
Let us analyze this solution;
Problem ; Deforestation owing to growing of crops
- Growing of corn and sunflowers does not affect the forest in an area. To grow these crop species, clear cutting might not necessarily be carried out.
- The vegetable oil will provide the farmers with an alternate source of income.
- The forest will then be preserved.
The first solution takes the business away from the local area and the farmers will lose.
