Answer the following question given this paragraph: Bacteria can be used to make cheese from milk. The bacteria turn the milk sugars into lactic acid. The acid is what causes the milk to curdle to form cheese. Bacteria are also involved in producing other foods. Yogurt is made by using bacteria to ferment milk ( Figure below ). Fermenting cabbage with bacteria produces sauerkraut. Q: Bacteria can be used to make cheese from milk. the bacteria turn the milk sugars into what? A:

OPTIONS:
- acetic acid
- ionic acid
- hydrochloric acid
- lactic acid

Answer: lactic acid

Problem: OPTIONS:
- suggesting reproduction
- subject reproduction
- asexual reproduction
- sexual reproduction
Q: Answer the following question given this paragraph: Sexual reproduction In eukaryotes, the major mechanism for shuffling genes is sexual reproduction. Because sex (usually) requires that organisms cooperate sex represents an example of social evolution. So what are the benefits of sexual reproduction? 342 Sexual reproduction involves the alternation of diploid (two copies of each chromosome) and haploid (one copy of each chromosome) cell types. In a diploid cell, the two copies of a particular gene can be different, the the organisms is said to be heterozygous for that gene. Different alleles can (but do not necessarily do) encode functionally distinct gene products and can be associated with different phenotypes (discussed in greater detail in the future two-semester version). We can then characterize different alleles with respect to one one another. Assume that allele-1 is associated with phenotype-1 342. Q: In eukaryotes, the major mechanism for shuffling genes is what? A:
Answer: sexual reproduction

Problem:OPTIONS:
- vascular plants
- nonpermeable
- photoreactive
- nonvascular

Answer the following question given this paragraph: Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss. The familiar, green, photosynthetic moss plants are gametophytes . The sporophyte generation is very small and dependent on the gametophyte plant. Q: What are the only plants with a life cycle in which the gametophyte generation is dominant? A:
****
A: nonvascular

Answer the following question given this paragraph: Clouds form when air in the atmosphere reaches the dew point. Clouds may form anywhere in the troposphere. Clouds that form on the ground are called fog . Q: What are clouds that form on the ground called? A:
OPTIONS:
- haze
- smoke
- canopy
- fog
fog

Answer the following question given this paragraph: Long-term or high-dose exposure to radiation can harm both living and nonliving things. Radiation knocks electrons out of atoms and changes them to ions. It also breaks bonds in DNA and other compounds in living things. One source of radiation that is especially dangerous to people is radon. Radon is a radioactive gas that forms in rocks underground. It can seep into basements and get trapped inside buildings. Then it may build up and become harmful to people who breathe it. Long-term exposure to radon can cause lung cancer. Q: This knocks electrons from atoms and turns them into ions? A:
OPTIONS:
- convection
- chemical reactions
- evaporation
- radiation

Answer: radiation

input with options: Answer the following question given this paragraph: Fossils are the preserved remains or traces of organisms that lived long ago. They form mainly when minerals in water turn remains to stone. Fossils can be dated using methods such as carbon-14 dating or their positions in rock layers. Q: What term is defined as the preserved remains or traces of organisms that lived during earlier ages? A:
OPTIONS:
- bones
- waste
- deposits
- fossils
output:
fossils
