Answer the following question given this paragraph: Figure 46.15 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. Volcanic activity and, more recently, human emissions, bring this stored carbon back into the carbon cycle. (credit: modification of work by John M. Evans and Howard Perlman, USGS). Q: Respiration cycles the organic carbon into which gas? Choices: - liquid dioxide - phosphorus dioxide - oxygen - carbon dioxide A:
carbon dioxide
Answer the following question given this paragraph: Earth rotates on its axis every 24 hours. Q: How long does it take for earth to rotate on it's axis one time? Choices: - 6 hours - 12 hours - 26 hours - 24 hours A:
24 hours
Q: Answer the following question given this paragraph: Renewable resources can be renewed as they are used. An example is timber, which comes from trees. New trees can be planted to replace those that are cut down. Sunlight is a renewable resource. It seems we will never run out of that!. Q: Timber, obtained from trees that can be replanted to replace those that are cut down, is an example of what type of resource? Choices: - nonrenewable - fossil fuel - mineral - renewable A:
A: renewable
Question: Answer the following question given this paragraph: Regardless of the appearance of stained or unstained tissue, the cell bodies of neurons or axons can be located in discrete anatomical structures that need to be named. Those names are specific to whether the structure is central or peripheral. A localized collection of neuron cell bodies in the CNS is referred to as a nucleus. In the PNS, a cluster of neuron cell bodies is referred to as a ganglion. Figure 12.4 indicates how the term nucleus has a few different meanings within anatomy and physiology. It is the center of an atom, where protons and neutrons are found; it is the center of a cell, where the DNA is found; and it is a center of some function in the CNS. There is also a potentially confusing use of the word ganglion (plural = ganglia) that has a historical explanation. In the central nervous system, there is a group of nuclei that are connected together and were once called the basal ganglia before "ganglion" became accepted as a description for a peripheral structure. Some sources refer to this group of nuclei as the "basal nuclei" to avoid confusion. Q: What is a cluster of neuron cell bodies in the pns called? Choices: - groupilion - gangnem - crystals - ganglion A:
Answer: ganglion
*Question*
Answer the following question given this paragraph: three building blocks of most matter. (The third is the neutron, which is neutral, carrying no charge. ) Other charge-carrying particles are observed in cosmic rays and nuclear decay, and are created in particle accelerators. All but the electron and proton survive only a short time and are quite rare by comparison. Q: What type of charge does a neutron have? Choices: - negative charge - positive charge - half charge - neutral or no charge A:
**Answer**
neutral or no charge
Answer the following question given this paragraph: Ceres ( Figure below ) is a rocky body that orbits the Sun. It could be an asteroid or a planet. Before 2006, Ceres was thought to be the largest asteroid. Is it an asteroid? Ceres is in the asteroid belt. But it is by far the largest object in the belt. Ceres has such high gravity that it is spherical. Q: What explains the spherical shape of ceres, once thought to be the largest asteroid? Choices: - orbital plane - space debris - low gravity - high gravity A:
high gravity
