Q: Answer the following question given this paragraph: Q: Comparisons of amino acid sequences can shed light on the evolutionary divergence of what? A:

OPTIONS:
- mammals
- dinosaurs
- birds
- related species

A: related species

input: OPTIONS:
- permanent
- instantaneous
- critical
- irreversible Now, answer this question: Answer the following question given this paragraph: Some chemical reactions can occur in only one direction. These reactions are called irreversible reactions. The reactants can change to the products, but the products cannot change back to the reactants. These reactions are like making a cake. The ingredients of a cakesuch as eggs and flourare the reactants. They are mixed together and baked to form the cake, which is the product (see Figure below ). The cake can't be "unbaked" and "unmixed" to change it back to the raw eggs, flour, and other ingredients. So making a cake is irreversible. Q: What are reactions that can occur only in one direction called? A:
A:
output: irreversible

Answer the following question given this paragraph: Nearly all fish reproduce sexually, and most species have separate sexes. Those without separate sexes avoid self-fertilization by producing sperm and eggs at different times. Each fish typically produces a large number of gametes. In most fish species, fertilization takes place externally. These fish are oviparous . Eggs are laid and embryos develop outside the mother's body. In a minority of fish, including sharks, eggs develop inside the mother's body but without nourishment from the mother. These fish are ovoviviparous . Q: How do the vast majority of fish reproduce? A:

OPTIONS:
- by budding
- asexually
- cloning
- sexually

Answer: sexually

Problem: OPTIONS:
- atomic volume unit
- particle mass unit
- nuclear mass unit
- atomic mass unit
Q: Answer the following question given this paragraph: Chadwick's work resulted in a new understanding of the nucleus of the atom; it is comprised of both protons and neutrons. Because the masses of subatomic particles are so small, a new unit, called an atomic mass unit (amu), was defined. Protons and neutrons each have a mass of approximately one amu. The Table below describes the characteristics of the three subatomic particles we have discussed. Q: Because the masses of subatomic particles are so small, a new unit, called what, was defined? A:
Answer: atomic mass unit

A: photosynthesis

Problem:OPTIONS:
- calcium
- water
- hydrogen
- hydrogen peroxide

Answer the following question given this paragraph: Peroxisomes Like lysosomes, a peroxisome is a membrane-bound cellular organelle that contains mostly enzymes (Figure 3.17). Peroxisomes perform a couple of different functions, including lipid metabolism and chemical detoxification. In contrast to the digestive enzymes found in lysosomes, the enzymes within peroxisomes serve to transfer hydrogen atoms from various molecules to oxygen, producing hydrogen peroxide (H2O2). In this way, peroxisomes neutralize poisons such as alcohol. In order to appreciate the importance of peroxisomes, it is necessary to understand the concept of reactive oxygen species. Q: Peroxisomes perform a couple of different functions, including lipid metabolism and chemical detoxification. in contrast to the digestive enzymes found in lysosomes, the enzymes within peroxisomes serve to transfer hydrogen atoms from various molecules to oxygen, producing what? A:
****
A:
hydrogen peroxide
