Q: Deceleration is the opposite of what? Read this paragraph and choose the correct option from the provided answers: Discussion The minus sign indicates that acceleration is to the left. This sign is reasonable because the train initially has a positive velocity in this problem, and a negative acceleration would oppose the motion. Again, acceleration is in the same direction as the change in velocity, which is negative here. This acceleration can be called a deceleration because it has a direction opposite to the velocity. Choices: - stopping - stimulation - vibration - acceleration A:
acceleration

Q: What occurs when the pancreas doesn't make enough insulin or else the body's cells are resistant to the effects of insulin? Read this paragraph and choose the correct option from the provided answers: Diabetes is another type of noninfectious disease. Diabetes occurs when the pancreas doesn't make enough insulin or else the body's cells are resistant to the effects of insulin. Insulin is a hormone that helps cells absorb glucose from the blood. Choices: - hepatitis - anemia - colitis - diabetes A:
(Answer)
diabetes

Ques: Q: Which procedure helps modern nuclear physics convert lead into gold? Read this paragraph and choose the correct option from the provided answers: The alchemists were never successful in changing lead into gold. But modern nuclear physics can accomplish this task. Lead is subjected to nuclear bombardment in a particle accelerator. A small amount of gold can be obtained by this process. However, the cost of the procedure is far more than the amount of gold obtained. So the dream of the alchemists has never (and will never) come true. Choices: - nuclear fission - matter fusion - evaporation - nuclear bombardment A:
Ans: nuclear bombardment

Q: What are are segmented invertebrates in phylum annelida called? Read this paragraph and choose the correct option from the provided answers: Annelids are segmented invertebrates in Phylum Annelida. They include earthworms, polychaete worms, and leeches. Annelids have a coelom and several organ systems. Their body segments may have a variety of different structures such as tentacles or suckers. Annelids may be predators, parasites, filter feeders, or decomposers. Choices: - flatworms - fungi - corals - annelids A:
(A).
annelids

Ques:Q: What structures of the cardiovascular system help regulate body processes by either constricting or dilating? Read this paragraph and choose the correct option from the provided answers: Blood vessels help regulate body processes by either constricting (becoming narrower) or dilating (becoming wider). These actions occur in response to signals from the autonomic nervous system or the endocrine system. Constriction occurs when the muscular walls of blood vessels contract. This reduces the amount of blood that can flow through the vessels (see Figure below ). Dilation occurs when the walls relax. This increases blood flows through the vessels. Choices: - muscles - cartilage - capillaries - blood vessels A:

Ans:blood vessels

Q: The active site can only bind certain what? Read this paragraph and choose the correct option from the provided answers: The active site is specific for the reactants of the biochemical reaction the enzyme catalyzes. Similar to puzzle pieces fitting together, the active site can only bind certain substrates. Choices: - electrons - membranes - proteins - substrates A:
substrates
