Answer the following question given this paragraph: The sensory division of the peripheral nervous system carries messages from sense organs and internal organs to the central nervous system. For example, it carries messages about images from the eyes to the brain. Once the messages reach the brain, the brain interprets the information. Q: What system carries messages from sense organs and internal organs to the central nervous system? Choices: - sensitive nervous system - respiratory system - auxiliary nervous system - peripheral nervous system A:
(Answer)
peripheral nervous system

Ans: partial pressure

Answer the following question given this paragraph: Q: Because plants are relatively immobile, they can function with bulky energy storage in the form of what? Choices: - fat - protein - dioxide - starch A:
(A).
starch
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
Answer the following question given this paragraph: The type of chemical signal a cell will send differs depending on the distance the message needs to go. For example, hormones , ions, and neurotransmitters are all types of signals that are sent depending on the distance the message needs to go. Endocrine signals are hormones, produced by endocrine organs. These signals travel through the blood stream to reach all parts of the body. Q: Hormones, ions, and neurotransmitters are all types of what? Choices: - nutrients - pathogens - proteins - chemical signals A:
chemical signals
