Multiple myeloma<span> is cancer that forms in your plasma cells and causes cancer cells to accumulate in the bone marrow. Plasma cells are cells which help you fight infections by making antibodies that attack germs. </span>If signs and symptoms develop like bone pain or nausea, a number of treatments can be done to help control your multiple myeloma.
A nurse caring for a client with multiple myeloma is most likely to see his blood count. Complete blood count (CBC), is done to measure the levels of red cells, white cells, and platelets in the blood. If there are too many myeloma cells in the bone marrow, the most common finding is a low red blood cell count.
During Asexual reproduction, in the interior side of Sporangium spores are made by mold and spreading of more mold occurs and Sporangium will be breaking during the time, when the spores are ready for leaving out.
<u>Explanation:</u>
The formation of spores is the asexual reproduction method that occurs in fungi which is a non flowering plant and bacteria. Many number of smaller and tiny spores that are tough, round shaped and microscopic, are produced by parent plants that has the ability to grow into many newer plants in asexual reproduction method only under certain conditions. Multiple number of spores in the sacs of Rhizopus that is called as sporangia. Te structure of these sporangia is like a knob and these are are present at the top of hyphae which is like a thread.
When these sporangia bursts, the spores are scattered by rain, wind or insects and under suitable conditions develop into a new Rhizopus plant, when they fall on a suitable substance like bread. When a break occurs in these sporangia, scattering of these spores occurs and these develop into a new plant under some suitable conditions, when these falls on a substance say for an instance bread.
Answer:
C. III, VII, IX, and X
Explanation:
The parasympathetic division of autonomous nervous system is also known as craniosacral division. The cell bodies of preganglionic neurons of parasympathetic division are located in the lateral gray matter of sacral segments (S2-S4) of spinal cord and in the nuclei of four cranial nerves in the brain stem. These cranial nerves as namely: oculomotor nerve (III), facial nerve (VII), glossopharyngeal nerve (IX), vagus nerve (X).
Explanation:
B) False
Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer
Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.
Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.
