Answer the following question given this paragraph: Pathways of Hormone Action The message a hormone sends is received by a hormone receptor, a protein located either inside the cell or within the cell membrane. The receptor will process the message by initiating other signaling events or cellular mechanisms that result in the target cell's response. Hormone receptors recognize molecules with specific shapes and side groups, and respond only to those hormones that are recognized. The same type of receptor may be located on cells in different body tissues, and trigger somewhat different responses. Thus, the response triggered by a hormone depends not only on the hormone, but also on the target cell. Once the target cell receives the hormone signal, it can respond in a variety of ways. The response may include the stimulation of protein synthesis, activation or deactivation of enzymes, alteration in the permeability of the cell membrane, altered rates of mitosis and cell growth, and stimulation of the secretion of products. Moreover, a single hormone may be capable of inducing different responses in a given cell. Q: Receptors for what chemical messengers recognize molecules with specific shapes and side groups, and respond only to those that are recognized? A:
****
A: hormones

Answer the following question given this paragraph: Insects generally have two pairs of wings for flight. Wings are part of the exoskeleton and attached to the thorax. Insect wings show a lot of variation. As you can see in Figure below , butterfly wings are paper-thin, whereas beetle wings are like armor. Not all insect wings work the same way, either. They differ in how the muscles are attached and whether the two pairs of wings work independently or together. Besides flight, wings serve other functions. They may protect the body (beetles), communicate visually with other insects (butterflies), or produce sounds to attract mates (katydids). Q: Insect wings are part of the exoskeleton and attached to the what? A:
OPTIONS:
- neck
- head
- spines
- thorax
thorax

Answer the following question given this paragraph: The gene theory is the idea that the characteristics of living organisms are controlled by genes, which are passed from parents to their offspring. A gene is a segment of DNA that has the instructions to encode a protein. Genes are located on larger structures, called chromosomes , that are found inside every cell. Chromosomes, in turn, contain large molecules known as DNA (deoxyribonucleic acid). Molecules of DNA are encoded with instructions that tell cells what to do. To see how this happens, click on the animation titled Journey into DNA at the following link: http://www. pbs. org/wgbh/nova/genome/dna. html . Q: Which theory is the idea that the characteristics of living organisms are controlled by genes, which are passed from parents to their offspring? A:
OPTIONS:
- species theory
- evolution theory
- fossil theory
- gene theory

Answer: gene theory

Question: Answer the following question given this paragraph: Specifically for the strong nuclear force, Yukawa proposed that a previously unknown particle, now called a pion, is exchanged between nucleons, transmitting the force between them. Figure 33.3 illustrates how a pion would carry a force between a proton and a neutron. The pion has mass and can only be created by violating the conservation of mass-energy. This is allowed by the Heisenberg uncertainty principle if it occurs for a sufficiently short period of time. As discussed in Probability: The Heisenberg Uncertainty Principle the Heisenberg uncertainty principle relates the uncertainties E in energy and t in time by. Q: The pion can only be created by violating the conservation of what? A:
OPTIONS:
- quantum physics
- time-space
- momentum
- mass-energy
Answer: mass-energy

input with options: Answer the following question given this paragraph: Pollutants that enter an aquifer spread outward from the source. They spread in the direction the water is moving. Q: Which direction from the source do pollutants in an aquifer spread? A:
OPTIONS:
- southward
- forward
- inward
- outward
output: outward

Problem: OPTIONS:
- mars
- jupitor
- earth
- mercury
Q: Answer the following question given this paragraph: Mercury is the smallest planet. It has no moon. It is also the planet closest to the Sun. Pictured below is the surface of Mercury covered with craters ( Figure below ), like Earth's Moon. Many of the impact craters are billions of years old. This means that Mercury hasn't changed much geologically for billions of years. It has no plate tectonics. With only a trace of an atmosphere, it has no weather to wear down the ancient craters. Q: What is the name of the smallest planet in our solar system, which is also nearest to the sun? A:
Answer:
mercury
