Answer;
Starch
Explanation;
-Starch is a polymer of glucose that is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin.
-Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose.
-Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds.
It’s D red marrow because I said so
Answer:
Prions are abnormally shaped proteins that cause spongiform encephalopathies. (Ans C)
Explanation:
Prions : Prions are proteinaceous infectious particle or misfolded proteins with the ability to transmit their misfolded shape into normal shape protein. They are also responsible for some neurodegenerative diseases in mammals. They can affect both animals as well as humans.
Prion disease occurs when normal prion protein (present on the surface of many cells) becomes clump (abnormal) in the brain. This accumulation of abnormal protein in the brain can cause disease.
Spongiform encephalopathies also called prion disease. Spongiform encephalopathies affect the nervous system and brain of animals & humans. It is caused by a degeneration of brain tissues giving it a spongy appearance.
Answer:
D. They both decrease genetic variation.
Explanation:
In natural selection, variation happens to produce more fit organisms. The natural selection is a different type such as stabilizing selection, directional selection, and disruptive selection. In both cases, variation occurs but the variation rate is different. Therefore, the common thing between stabilizing selection and disruptive selection is variation. The variation rate is slow in stabilizing selection. Hence in this selection less phenotype characters are seen. In disruptive selection, variation is random and extreme. Thus more phenotype individuals are formed due to disruptive selection.
Answer:c. Two identical cells are formed
