Answer:
Her minimum height must be 5'5" and her minimum weight must be 150 lb
Explanation:
The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.
Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.
The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
The answer is B. A dependent variable is one that varies according to the modulated independent variable. In this case, the independent variable is A -‘The amount of Drug x given to the mice’ since it is the one that is being controlled in the experiment.
Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.
Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.
Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
