Ques: Answer the following question given this paragraph: Scientists may focus on very different aspects of the natural world. For example, some scientists focus on the world of tiny objects, such as atoms and molecules. Other scientists devote their attention to huge objects, such as the sun and other stars. But all scientists have at least one thing in common. They want to understand how and why things happen. Achieving this understanding is the goal of science. Q: The desire to understand how and why things happen is shared by all branches of what? Choices: - population - society - government - science A:
Ans: science

Answer the following question given this paragraph: Nervous Tissues Nervous tissues are made of cells specialized to receive and transmit electrical impulses from specific areas of the body and to send them to specific locations in the body. The main cell of the nervous system is the neuron, illustrated in Figure. Q: What is the main type of cell in the nervous system called? Choices: - sensory - conduction - axon - neuron A:
(A).
neuron
Ques:Answer the following question given this paragraph: data are passed to new generations; and even how proteins are built to required specifications. All these abilities depend on the pairing of complementary bases. Figure 19.7 "Complementary Base Pairing" shows the two sets of base pairs and illustrates two things. First, a pyrimidine is paired with a purine in each case, so that the long dimensions of both pairs are identical (1.08 nm). If two pyrimidines were paired or two purines were paired, the two pyrimidines would take up less space than a purine and a pyrimidine, and the two purines would take up more space, as illustrated in Figure 19.8 "Difference in Widths of Possible Base Pairs". If these pairings were ever to occur, the structure of DNA would be like a staircase made with stairs of different widths. For the two strands of the double helix to fit neatly, a pyrimidine must always be paired with a purine. The second thing you should notice in Figure 19.7 "Complementary Base Pairing" is that the correct pairing enables formation of three instances of hydrogen bonding between guanine and cytosine and two between adenine and thymine. The additive contribution of this hydrogen bonding imparts great stability to the DNA double helix. Q: The "double helix" shape is associated with what substance found in cells? Choices: - genes - bacteria - plasma - dna A:

Ans:dna
Ques: Answer the following question given this paragraph: Yeasts are crucial for the fermentation process that makes beer, wine, and bread. Fermentation occurs in the absence of oxygen and allows the first step of cellular respiration, glycolysis, to continue. Q: What is crucial for the fermentation progress in making bread? Choices: - larvae - fruit - cold - yeast A:
Ans:
yeast
