Q: Answer the following question given this paragraph: Scientists also have to "check their work. " The results of an investigation are not likely to be well accepted unless the investigation is repeatedusually many timesand the same result is always obtained. Getting the same result when an experiment is repeated is called replication . If research results can be replicated, it means they are more likely to be correct. Repeated replication of investigations may turn a hypothesis into a theory. On the other hand, if results cannot be replicated they are likely to be incorrect. Q: Getting the same result when an experiment is repeated is called what? A:

OPTIONS:
- mutation
- initiation
- repetition
- replication

A: replication

input: OPTIONS:
- velocity
- demand
- energy
- pressure Now, answer this question: Answer the following question given this paragraph: The canister on the left contains a gas at a certain pressure. The attached air pump is then used to double the amount of gas in the canister. Since the canister cannot expand, the increased number of air molecules will strike the inside walls of the canister twice as frequently as they did before. The result is that the pressure inside the canister doubles. As you might imagine, if more and more air is continually added to a rigid container, it may eventually burst. Reducing the number of molecules in a rigid container has the opposite effect and the pressure decreases. Q: Reducing the number of molecules in a rigid container causes what to decrease? A:
A:
output: pressure

Answer the following question given this paragraph: Some prokaryotes form structures consisting of many individual cells, like the cells in Figure below . This is called a biofilm. A biofilm is a colony of prokaryotes that is stuck to a surface. The surface might be a rock or a host's tissues. The sticky plaque that collects on your teeth between brushings is a biofilm. It consists of millions of prokaryotic cells. Q: A biofilm is a colony of prokaryotes that is stuck to what? A:

OPTIONS:
- the middle
- the bottom
- skin
- surface

Answer: surface

Problem: OPTIONS:
- lungs
- phototropism
- pores
- gills
Q: 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:
Answer: gills

Problem:OPTIONS:
- sperm
- gametophyte
- ovary
- sporophyte

Answer the following question given this paragraph: Seeds and Pollen as an Evolutionary Adaptation to Dry Land Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into a sporophyte. Storage tissue to sustain growth and a protective coat give seeds their superior evolutionary advantage. Several layers of hardened tissue prevent desiccation, and free reproduction from the need for a constant supply of water. Furthermore, seeds remain in a state of dormancyinduced by desiccation and the hormone abscisic aciduntil conditions for growth become favorable. Whether blown by the. Q: Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into what? A:
****
A: sporophyte

Problem:OPTIONS:
- liquid
- solid
- vapor
- gas

Answer the following question given this paragraph: If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas. The particles can pull apart and spread out. This explains why gases have neither a fixed volume nor a fixed shape. Q: If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a what? A:
****
A:
gas
