Answer the following question given this paragraph: Metamorphism does not cause a rock to melt completely. It only causes the minerals to change by heat or pressure. Q: What process does not cause a rock to melt completely, instead causing the minerals to change by heat or pressure? Choices: - sedimentation - oxidation - igneous extrusion - metamorphism A:
metamorphism
Answer the following question given this paragraph: Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 3.5). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation. Q: Unlike archaea and eukaryotes, bacteria have a cell wall made of what? Choices: - substrates - phospholipids - hydrogen - peptidoglycan A:
peptidoglycan
Q: Answer the following question given this paragraph: 46.4 The interplay of tropic and sex hormones regulates mammalian reproduction. Q: What two types of hormones regulate mammalian reproduction? Choices: - tropic and subtropic - pheromones and enzymes - endorphins and adrenaline - tropic and sex A:
A: tropic and sex
Question: Answer the following question given this paragraph: Q: What structures on the gastrodermal cells keep the contents of the gastrovascular cavity agitated and help distribute nutrients? Choices: - telomeres - sporangia - nucleus - flagella A:
Answer: flagella

Answer the following question given this paragraph: Selective precipitation can also be used in qualitative analysis. In this method, reagents are added to an unknown chemical mixture in order to induce precipitation. Certain reagents cause specific ions to precipitate out; therefore, the addition of the reagent can be used to determine whether the ion is present in the solution. Q: In qualitative analysis, reagents are added to an unknown chemical mixture in order to induce what? Choices: - motion - sunlight - erosion - precipitation A:
**Answer**
precipitation

Answer the following question given this paragraph: White Columns Just as the gray matter is separated into horns, the white matter of the spinal cord is separated into columns. Ascending tracts of nervous system fibers in these columns carry sensory information up to the brain, whereas descending tracts carry motor commands from the brain. Looking at the spinal cord longitudinally, the columns extend along its length as continuous bands of white matter. Between the two posterior horns of gray matter are the posterior columns. Between the two anterior horns, and bounded by the axons of motor neurons emerging from that gray matter area, are the anterior columns. The white matter on either side of the spinal cord, between the posterior horn and the axons of the anterior horn neurons, are the lateral columns. The posterior columns are composed of axons of ascending tracts. The anterior and lateral columns are composed of many different groups of axons of both ascending and descending tractsthe latter carrying motor commands down from the brain to the spinal cord to control output to the periphery. Q: The brain is said to contain gray matter, while what related structure contains white matter separated into columns? Choices: - brain stem - amygdala - orbital lobe - spinal cord A:
**Answer**
spinal cord
