Ques:Q: In what organ does pepsin help break down proteins? Read this paragraph and choose the correct option from the provided answers: Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. For example, every time you digest food, acids and bases are at work in your digestive system. Consider the enzyme pepsin, which helps break down proteins in the stomach. Pepsin needs an acidic environment to do its job, and the stomach secretes a strong acid that allows pepsin to work. However, when stomach contents enter the small intestine, the acid must be neutralized. This is because enzymes in the small intestine need a basic environment in order to work. An organ called the pancreas secretes a strong base into the small intestine, and this base neutralizes the acid. Choices: - kidney - liver - skin - stomach A:

Ans:stomach

Ques:Q: How many chromosomes do mature gametes contain? Read this paragraph and choose the correct option from the provided answers: Spermatogenesis As just noted, spermatogenesis occurs in the seminiferous tubules that form the bulk of each testis (see Figure 27.4). The process begins at puberty, after which time sperm are produced constantly throughout a man's life. One production cycle, from spermatogonia through formed sperm, takes approximately 64 days. A new cycle starts approximately every 16 days, although this timing is not synchronous across the seminiferous tubules. Sperm countsthe total number of sperm a man producesslowly decline after age 35, and some studies suggest that smoking can lower sperm counts irrespective of age. The process of spermatogenesis begins with mitosis of the diploid spermatogonia (Figure 27.5). Because these cells are diploid (2n), they each have a complete copy of the father's genetic material, or 46 chromosomes. However, mature gametes are haploid (1n), containing 23 chromosomesmeaning that daughter cells of spermatogonia must undergo a second cellular division through the process of meiosis. Choices: - 19 - 13 - 17 - 23 A:

Ans:
23
