Answer the following question given this paragraph: As the human population continues to grow, different factors limit population in different parts of the world. Space, clean air, clean water, and food to feed everyone are limiting in some locations. Worldwide though, human ingenuity has not placed a limit on the population. Not only does the population increase, the rate of population growth increases. Q: Is the rate of population growth increasing or decreasing? A:
OPTIONS:
- suggesting
- Vanishing.
- preventing
- increasing
increasing

Answer the following question given this paragraph: Angiosperms are plants that produce flowers and fruit. Q: What is the term for plants that produce flowers and fruit? A:
OPTIONS:
- endosperms
- spores
- gymnosperms
- angiosperms

Answer: angiosperms

Question: Answer the following question given this paragraph: As mentioned earlier, echinoderms show radial symmetry. Other key echinoderm features include an internal skeleton and spines, as well as a few organs and organ systems. Although echinoderms look like they have a hard exterior, they do not have an external skeleton. Instead, a thin outer skin covers an internal skeleton made of tiny plates and spines. This provides rigid support. Some groups of echinoderms, such as sea urchins ( Figure below ), have spines that protect the organism. Sea cucumbers use these spines to help them move. Q: What type of symmetry do echinoderms show? A:
OPTIONS:
- mirrored
- lateral
- parallel
- radial
Answer: radial

input with options: Answer the following question given this paragraph: cell that transmits electrical impulses in the nervous system; commonly called nerve cell. Q: What type of cell transmits electrical impulses in the nervous system? A:
OPTIONS:
- toxin cell
- Large Cell
- trace cell
- nerve cell
output: nerve cell

Q: Answer the following question given this paragraph: Another type of luminescence is called electroluminescence. In this process, a substance gives off light when an electric current passes through it. Gases such as neon, argon, and krypton produce light by this means. The car dash lights in the Figure below are produced by electroluminescence. Q: Gases such as neon, argon, and krypton produce what using electroluminescence? A:

OPTIONS:
- heat
- colors
- electricity
- light

A: light

Answer the following question given this paragraph: Catabolic Reactions Catabolic reactions break down large organic molecules into smaller molecules, releasing the energy contained in the chemical bonds. These energy releases (conversions) are not 100 percent efficient. The amount of energy released is less than the total amount contained in the molecule. Approximately 40 percent of energy yielded from catabolic reactions is directly transferred to the high-energy molecule adenosine triphosphate (ATP). ATP, the energy currency of cells, can be used immediately to power molecular machines that support cell, tissue, and organ function. This includes building new tissue and repairing damaged tissue. ATP can also be stored to fulfill future energy demands. The remaining 60 percent of the energy released from catabolic reactions is given off as heat, which tissues and body fluids absorb. Structurally, ATP molecules consist of an adenine, a ribose, and three phosphate groups (Figure 24.2). The chemical bond between the second and third phosphate groups, termed a high-energy bond, represents the greatest source of energy in a cell. It is the first bond that catabolic enzymes break when cells require energy to do work. The products of this reaction are a molecule of adenosine diphosphate (ADP) and a lone phosphate group (Pi). ATP, ADP, and Pi are constantly being cycled through reactions that build ATP and store energy, and reactions that break down ATP and release energy. Q: Catabolic reactions break down large organic molecules into smaller molecules, releasing the energy contained in what? A:
OPTIONS:
- molecular bonds
- liquid bonds
- crystals bonds
- chemical bonds
chemical bonds
