Answer the following question given this paragraph: Many species use their body shape and coloration to avoid being detected by predators. The tropical walking stick is an insect with the coloration and body shape of a twig, which makes it very hard to see when it is stationary against a background of real twigs (Figure 19.15a). In another example, the chameleon can change its color to match its surroundings (Figure 19.15b). Q: Many species use their body shape and coloration to avoid being detected by what? Choices: - biology - viruses - males - predators A:
predators
Answer the following question given this paragraph: 25.10 The Urinary System and Homeostasis The effects of failure of parts of the urinary system may range from inconvenient (incontinence) to fatal (loss of filtration and many others). The kidneys catalyze the final reaction in the synthesis of active vitamin D that in turn helps regulate Ca++. The kidney hormone EPO stimulates erythrocyte development and promotes adequate O2 transport. The kidneys help regulate blood pressure through Na+ and water retention and loss. The kidneys work with the adrenal cortex, lungs, and liver in the reninangiotensinaldosterone system to regulate blood pressure. They regulate osmolarity of the blood by regulating both solutes and water. Three electrolytes are more closely regulated than others: Na+, Ca++, and K+. The kidneys share pH regulation with the lungs and plasma buffers, so that proteins can preserve their three-dimensional conformation and thus their function. Q: What paired organs help regulate blood pressure through sodium ion and water retention and loss? Choices: - lungs - tissues - lymph nodes - kidneys A:
kidneys
Q: Answer the following question given this paragraph: To grow and develop, you must form new cells. Imagine how often your cells must divide during a growth spurt. Growing just an inch requires countless cell divisions. Your body must produce new bone cells, new skin cells, new cells in your blood vessels and so on. Q: A growth spurt requires constant divisions of what? Choices: - hairs - seeds - proteins - cells A:
A: cells
Question: Answer the following question given this paragraph: How about both? That would suggest that fungi can produce both diploid and haploid cells, which they can. Shown above are fungi mycelia and haploid spores. Spores allow fungi to reproduce through unfavorable conditions. Q: What particles allow fungi to reproduce through unfavorable conditions? Choices: - bosons - atoms - quarks - spores A:
Answer: spores

**Answer**
fog

Answer the following question given this paragraph: Aerobic respiration begins with the entry of the product of glycolysis, pyruvate, into the mitochondria. For each initial glucose molecules, two pyruvate molecules will enter the mitochondria. Pyruvate, however, is not the molecule that enters the Krebs cycle. Prior to entry into this cycle, pyruvate must be converted into a 2-carbon acetyl-CoenzymeA (acetyl-CoA) unit. The conversion of pyruvate into acetyl-CoA is referred to as the pyruvate dehydrogenase reaction. It is catalyzed by the pyruvate dehydrogenase complex. This process produces one NADH electron carrier while releasing a CO 2 molecule. This step is also known as the link reaction or transition step, as it links glycolysis and the Krebs cycle. Of course, as two pyruvates result from glycolysis, two acetyl-CoAs are produced as are 2 NADH molecules. Q: For each initial glucose molecules, two pyruvate molecules will enter where? Choices: - the plasma - the nucleus - Golgi apparatus - the mitochondria A:
(Answer)
the mitochondria
