Cold front brings a sudden drop in temperature sometimes with hail , thunder , and lightning . Warm fronts bring gentle rain or light snow , followed by warmer , milder weather . Stationary front brings a cold and warm air together and neither air mass has the force to moved the other . Occluded front brings a warm air mass that gets caught between two cold air masses .

Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
The correct answers are B; Displacement of people living near the proposed dam and C; Lower river water levels in other areas.
Further Explanation:
The hydropower dam uses water instead of coal to generate electricity. Since they are build on the water, they will be using that source as a way to generate electricity. This will cause the water levels to be lower in some areas along the river.
When building a dam, they will need to use property that is located on the river. Many people own homes along the river banks all over the world. The company who will be building the dam will usually buy out the property owners at a fair market price. This will mean that they will have to move and leave their homes. The homes are typically torn down to make way for the dam.
In some instances, the water bills for the people in the area may be raised also since so much water is being used by the hydropower dam.

Answer:
The sperm and egg have 1/2 the amount because when the sperm fertilizes the egg, it equals out to the regular amount of chromosomes. That is why we have half chromosomes from our dad and half chromosomes from our mom, equaling out to normal amount of chromosomes.
