Answer:
False
Explanation:
An organism's niche includes its environment, behaviors, and interactions. It also includes its role within the environment. The environment consists of living and nonliving components.
Answer:
The correct answer is: the antibodies' shape.
Explanation:
<u>Antibodies are proteins called immunoglobulins that serve the immune system by responding to a specific antigen and generating the proper counter to fight it. </u>
Each antibody consists of four polypeptides that form a "Y" shaped molecule. The Y shape is given by two heavy chains and two light chains.
<u>The tips of the Y are composed of 110-130 amino acids that vary greatly among other antibodies. This gives the antibody its </u><u>specificity</u><u>.</u>
Answer:
Nylon is a strong synthetic fibre, which resists abrasion. Nylon doesn’t shrink or stretch through washing, but it is degraded by ultraviolet light.
Explanation:
Nylon is made when the appropriate monomers (the chemical building blocks which make up polymers) are combined to form a long chain via a condensation polymerisation reaction. The monomers for nylon 6-6 are adipic acid and hexamethylene diamine. The two molecules are combined to create the polymer and water (H2O) is produced as a by-product. The water is removed from the production process as its continued presence stops the creation of more polymer. The polymer chain can be made up of over 20,000 monomer units, connected together via an amide group, which contains a nitrogen atom. The nylon molecules are very flexible with only weak forces, such as hydrogen bonds, between the polymer chains, which tend to tangle randomly. The polymer has to be warmed and drawn out to form strong fibres
Answer:
B. The inability to reabsorb all of the glucose filtered from the blood at the level of the kidneys.
Explanation:
Diabetes mellitus is a syndrome caused by either lack of insulin or decreased sensitivity of insulin receptors. Type I diabetes is due to lack of insulin secretion where as type II diabetes is due to decreased sensitivity of target tissue to the insulin hormone.
Polyuria i.e excess urine secretion and polydypsia i.e increased flluid intake due to increased thirst are the classic symptoms of diabetes. When the glucose level in blood increases, its not completely reabsorbed from the renal tubules in the kidney, the excess glucose thus enters into the filtrate and moves out along with urine. This normally happens if the blood glucose is as high as 180 mg/100 ml or above. The loss of glucose in urine causes osmotic diuresis. Due to the osmotic effect of glucose in the renal tubules, the tubular reabsorption of water decreases thereby increasing the overall volume of urine. Both extracellular and intracellular dehydration are symptoms of diabetes mellitus.
