Problem:OPTIONS:
- glucose
- proton
- nuclei
- mitochondria

Answer the following question given this paragraph: Cellular respiration occurs in the mitochondria. Figure 20.13 "Respiration" shows the mitochondrion's two membranes: outer andinner. The inner membrane is extensively folded into a series of internal ridges calledcristae. Thus there are two compartments in mitochondria: the intermembrane space, which lies between the membranes, and the matrix, which lies inside the inner membrane. Q: What part of the cell does cellular respiration occur? A:
****
A: mitochondria

Answer the following question given this paragraph: In saturated fatty acids , carbon atoms are bonded to as many hydrogen atoms as possible. This causes the molecules to form straight chains, as shown in Figure below . The straight chains can be packed together very tightly, allowing them to store energy in a compact form. This explains why saturated fatty acids are solids at room temperature. Animals use saturated fatty acids to store energy. Q: What do animals store with the help of saturated fatty acids? A:
OPTIONS:
- oxygen
- sugar
- protein
- energy
energy

Answer the following question given this paragraph: Natural gas burns cleaner than other fossil fuels. As a result, it causes less air pollution. It also produces less carbon dioxide than the other fossil fuels. Because it burns cleaner than other fossil fuels, natural gas has a good reputation. Still, natural gas does emit pollutants. Q: Natural gas burns cleaner and produces less carbon dioxide than fuels of what type? A:
OPTIONS:
- renewable fuels
- solar energy
- biofuels
- fossil fuels

Answer: fossil fuels

Question: Answer the following question given this paragraph: Darwin thought that evolution occurs gradually. This model of evolution is called gradualism. The fossil record better supports the model of punctuated equilibrium. In this model, long periods of little change are interrupted by bursts of rapid change. Q: Did darwin believe in punctuated equilibrium or gradualism? A:
OPTIONS:
- it depended
- neither
- punctuated equilibrium
- gradualism
Answer: gradualism

input with options: Answer the following question given this paragraph: All objects in the universe have an attraction to each other. This attraction is known as gravity ( Figure below ). The strength of the force of gravity depends on two things. One is the mass of the objects. The other is the distance between the objects. As an object's mass increases, the attraction increases. As the distance between the objects increases, the attraction decreases. Q: The attraction between all objects in the universe is known as ______. A:
OPTIONS:
- variation
- electricity
- magnetism
- gravity
output: gravity

Problem: OPTIONS:
- anal cavity
- eye cavity
- fluid cavity
- nasal cavity
Q: Answer the following question given this paragraph: Weeks 47 Respiratory development in the embryo begins around week 4. Ectodermal tissue from the anterior head region invaginates posteriorly to form olfactory pits, which fuse with endodermal tissue of the developing pharynx. An olfactory pit is one of a pair of structures that will enlarge to become the nasal cavity. At about this same time, the lung bud forms. The lung bud is a dome-shaped structure composed of tissue that bulges from the foregut. The foregut is endoderm just inferior to the pharyngeal pouches. The laryngotracheal bud is a structure that forms from the longitudinal extension of the lung bud as development progresses. The portion of this structure nearest the pharynx becomes the trachea, whereas the distal end becomes more bulbous, forming bronchial buds. A bronchial bud is one of a pair of structures that will eventually become the bronchi and all other lower respiratory structures (Figure 22.29). Q: Respiratory development in the embryo begins around week 4. ectodermal tissue from the anterior head region invaginates posteriorly to form olfactory pits, which fuse with endodermal tissue of the developing pharynx. an olfactory pit is one of a pair of structures that will enlarge to become this? A:
Answer:
nasal cavity
