input: OPTIONS:
- by budding
- asexually
- cloning
- sexually Now, answer this question: 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:
A:
output: sexually

Answer the following question given this paragraph: Which of the following statements about the anatomy of a mollusk is false? a. Mollusks have a radula for grinding food. A digestive gland is connected to the stomach. The tissue beneath the shell is called the mantle. The digestive system includes a gizzard, a stomach, a digestive gland, and the intestine. Mollusks have a muscular foot, which is used for locomotion and anchorage, and varies in shape and function, depending on the type of mollusk under study. In shelled mollusks, this foot is usually the same size as the opening of the shell. The foot is a retractable as well as an extendable organ. The foot is the ventral-most organ, whereas the mantle is the limiting dorsal organ. Mollusks are eucoelomate, but the coelomic cavity is restricted to a cavity around the heart in adult animals. The mantle cavity develops independently of the coelomic cavity. The visceral mass is present above the foot, in the visceral hump. This includes digestive, nervous, excretory, reproductive, and respiratory systems. Mollusk species that are exclusively aquatic have gills for respiration, whereas some terrestrial species have lungs for respiration. Additionally, a tongue-like organ called a radula, which bears chitinous tooth-like. Q: What do aquatic mollusk species use for respiration? A:

OPTIONS:
- lungs
- phototropism
- pores
- gills

Answer: gills

Problem: OPTIONS:
- constant
- mist
- solar
- drip

****
A: kinetic energy

Answer the following question given this paragraph: Suppose that you wanted to know how many hydrogen atoms were in a mole of water molecules. First, you would need to know the chemical formula for water, which is H 2 O. There are two atoms of hydrogen in each molecule of water. How many atoms of hydrogen would there be in two water molecules? There would be 2 2 = 4 hydrogen atoms. How about in a dozen? In that case a dozen is 12 so 12 2 = 24 hydrogen atoms in a dozen water molecules. To get the answers, (4 and 24) you had to multiply the given number of molecules by two atoms of hydrogen per molecule. So to find the number of hydrogen atoms in a mole of water molecules, the problem could be solved using conversion factors. Q: H2o is the chemical formula for what? A:
OPTIONS:
- glass
- smog
- salt
- water
water

Answer the following question given this paragraph: Superposition refers to the position of rock layers and their relative ages ( Figure below ). Relative age means age in comparison with other rocks, either younger or older. The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition. Q: Deeper layers of rock must be older than layers closer to the surface, this is the law of what? A:
OPTIONS:
- erosion
- diffraction
- flux
- superposition

Answer:
superposition
