Answer the following question given this paragraph: If more NH 3 were added, the reverse reaction would be favored. This "favoring" of a reaction means temporarily speeding up the reaction in that direction until equilibrium is reestablished. Recall that once equilibrium is reestablished, the rates of the forward and reverse reactions are again equal. The addition of NH 3 would result in increased formation of the reactants, N 2 and H 2 . Q: What's it called when the reaction is sped up until equilibrium is established? A:
****
A: favoring

Answer the following question given this paragraph: Hydrozoa includes nearly 3,500 species, most of which are marine. Most species in this class have both polyp and medusa forms in their life cycle. Many hydrozoans form colonies composed of branches of specialized polyps that share a gastrovascular cavity. Colonies may also be free-floating and contain both medusa and polyp individuals in the colony, as in the Portuguese Man O'War (Physalia) or By-the-Wind Sailor (Velella). Other species are solitary polyps or solitary medusae. The characteristic shared by all of these species is that their gonads are derived from epidermal tissue, whereas in all other cnidarians, they are derived from gastrodermal tissue (Figure 15.14ab).

Q: Most hydrozoa have both polyp and what forms in their life cycle? A:
OPTIONS:
- hydra
- globular
- polypoid
- medusa
medusa

Answer the following question given this paragraph: The Diversity of Life The fact that biology, as a science, has such a broad scope has to do with the tremendous diversity of life on earth. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. The evolution of various life forms on Earth can be summarized in a phylogenetic tree (Figure 1.17). A phylogenetic tree is a diagram showing the evolutionary relationships among biological species based on similarities and differences in genetic or physical traits or both. A phylogenetic tree is composed of nodes and branches. The internal nodes represent ancestors and are points in evolution when, based on scientific evidence, an ancestor is thought to have diverged to form two new species. The length of each branch is proportional to the time elapsed since the split. Q: What process of gradual change is the source of diversity of life on earth? A:
OPTIONS:
- variation
- creation
- development
- evolution

Answer: evolution

Question: Answer the following question given this paragraph: A monosaccharide is a simple sugar such as fructose or glucose. Fructose is found in fruits, whereas glucose generally results from the digestion of other carbohydrates. Glucose (C 6 H 12 O 6 ) is used for energy by the cells of most organisms, and is a product of photosynthesis. Q: A simple sugar such as fructose or glucose is also called a what? A:
OPTIONS:
- carbohydrate
- disaccharide
- galactose
- monosaccharide
Answer: monosaccharide

input with options: Answer the following question given this paragraph: The main reason that insects have been so successful is their ability to fly. Insects are the only invertebrates that can fly and the first animals to evolve flight. Flight has important advantages. It's a guaranteed means of escape from nonflying predators. It also aids in the search for food and mates. Q: What are the only invertebrates that can fly? A:
OPTIONS:
- birds
- amphibians
- mammels
- insects
output: insects

Problem: OPTIONS:
- mutation acids
- peptides
- enzymes
- amino acids
Q: Answer the following question given this paragraph: Just as millions of different words are spelled with our 26-letter English alphabet, millions of different proteins are made with the 20 common amino acids. However, just as the English alphabet can be used to write gibberish, amino acids can be put together in the wrong sequence to produce nonfunctional proteins. Although the correct sequence is ordinarily of utmost importance, it is not always absolutely required. Just as you can sometimes make sense of incorrectly spelled English words, a protein with a small percentage of "incorrect" amino acids may continue to function. However, it rarely functions as well as a protein having the correct sequence. There are also instances in which seemingly minor errors of sequence have disastrous effects. For example, in some people, every molecule of hemoglobin (a protein in the blood that transports oxygen) has a single incorrect amino acid unit out of about 300 (a single valine replaces a glutamic acid). That "minor" error is responsible for sickle cell anemia, an inherited condition that usually is fatal. Q: Just as millions of different words are spelled with our 26-letter english alphabet, millions of different proteins are made with the 20 common what? A:
Answer:
amino acids
