Which of the following is used for STRUCTURE and not for ENERGY?
A)glycogen which stores excess glucose consumed by animals
B)starch which stores excess glucose made during photosynthesis in plants *
C)cellulose which is difficult to break apart
Answer:
the answer is option c cellulose..
Explanation:
Cellulose is a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms. Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright. Humans cannot digest cellulose, but it is important in the diet as fibre.
Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as energy storage
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. The polysaccharide structure represents the main storage form of glucose in the body.
hope it helped you and the answer is correct
The term that is used for structure and not for energy is cellulose, which is difficult to break apart. The correct option is c.
What is cellulose?A molecule called cellulose is made up of hundreds, and occasionally even thousands, of carbon, hydrogen, and oxygen atoms. The primary component of plant cell walls, cellulose, keeps plants rigid and upright.
A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. Most green plants synthesize this polysaccharide as a form of energy storage.
Animals, fungi, and bacteria all use the multibranched polysaccharide of glucose known as glycogen to store energy. The primary form of glucose storage in the body is represented by the polysaccharide structure.
Therefore, the correct option is C) cellulose, which is difficult to break apart.

In an effort to identify the influence of genetic factors on both Type I diabetes and Type II diabetes, researchers calculated concordance rates for monozygotic twins. Concordance rates of 30–50% have been found for Type I diabetes and concordance rates of 80% for Type II. For both kinds of diabetes, dizygotic concordance rates were about 15%. What does this information suggest concerning the relative effect of genetic and environmental factors for each type of diabetes?a) Environmental factors have no role in the occurrence of either type of diabetes.b) Type II diabetes appears to be caused by a single, unidentified gene.c) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.d) Genetic factors have little or no role in the occurrence of Type I diabetes.e) Type II diabetes is primarily determined by non-genetic factors.
The correct answer is C) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.
Explanation:
Monozygotic or identical twins share the same genes; due to this, if twins have the same diseases or there are concordance rates, it can be concluded the disease or condition is influenced by genetics.
In the case of diabetes, the concordance rate for Type II diabetes was high (80%), which proves this type of diabetes is influenced to a large extend by genetics. Similarly, in Type I diabetes genetics seem to have an influence but this is not as strong as in Type II because the rates were lower (30-50%).
Moreover, the results of dizygotic twins (twins with different genes) show diabetes is influenced by genetics because in these twins the genetics are not the same, and therefore the concordance rate is low.

How does cell volume affect nutrient exchange between the cell and its external environment?
a. Cells with a large volume and small surface area are well-adapted for nutrient
exchange.
b. Very large cells are the best adapted for nutrient exchange.
c. The ratio of cell volume to surface area determines the efficiency of nutrient
exchange.
d. Very small cells are the best adapted for nutrient exchange.
e. Nutrient exchange is not impacted by cell volume.
Answer:
d. Very small cells are the best adapted for nutrient exchange.
Explanation:
The need to be able to pass nutrients and other substances into and out of the cell limits how big cells can get. The larger a cell is, the more difficult it is for nutrients and gases to move in and out of the cell because the volume is larger than the surface area. Smaller cells can exchange nutrients with the external environment more quickly.
The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in water. In contrast, glycogen obtained from muscle or liver disperses readily in hot water to make a turbid solution. Despite their markedly different physical properties, both substances are (14)-linked D-glucose polymers of comparable molecular weight. What structural features of these two polysaccharides underlie their different physical properties
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.

which theory states that homo sapiens began in a single geographical area and spread out from there?
a. out of africa theory
b. tectonic theory
c. multi-regional theory
Answer:
The out of Africa theory states that Homo sapiens began in a single geographical area and spread out from there.
Explanation:
A is correct because the ''out of Africa theory'' suggests that the Homo sapiens began as a species in Africa and from there it gradually spread out on the other continents across the world.
B is not correct because the ''tectonic theory'' is a theory that has nothing to do with the Homo sapiens species, but it is a theory about the movement of tectonic plates.
C is not correct because the multi-regional theory suggests that the Homo sapiens evolved into multiple regions simultaneously, not in one region only.
