Answer:
A. Areas at high elevations have cooler temperatures.
Explanation:
Areas with high altitude or elevations have cooler temperatures because <u>air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.</u>
Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.
Hence, the correct option is "A. Areas at high elevations have cooler temperatures."
This first step to protecting this endangered species of snail is to preserve its existing habitat. This means that steps need to be taken to ensure that <span>Chittenango Falls state park continues to offer a refuge to this snail, and that steps are taken to improve the water quality in the park. A scientific study can be run to identify the pollutants and their concentrations that are having a negative effect on the snail species. For this, water quality testing can be conducted to first identify any pollutants. Once suspect pollutants are identified, ecotoxicology tests can be run to identify concentrations of the pollutants that have an effect on the snail. Both acute (short term) and chronic (long term) tests would have to be conducted, looking at mortality as well as sub-acute end points such as growth and reproduction. Once concentrations of pollutants are identified that would negatively affect the snail, we can call these 'water quality guidelines' that we would need to keep water quality within. We can then identify sources of these pollutants upstream, and take steps to reduce the pollution at source, by forcing factories to treat their water more rigorously or changing upstream land use. Finally, what can also be considered is introducing the snail species to new habitat within the State of New York. We must be careful here though as the actions of man have spread invasive species globally. </span>
Answer:
D. they are usually dominant or recessive.
Explanation:
alleles are pairs of genes found on a particular spot a chromosome. If one is dominant over the other it give rise to a particular trait.
<span>The sunspots are eruptions of heat and light energy emitting from the surface of the sun. These can increase our energy absorption many times above normal. Especially if it is pointed directly at the earth. These have been known to disrupt several bands in the radio spectrum and have knocked out communications of satellites. Naturally all this energy would have a great effect on our earth in many ways, climate included.</span>
