Explanation:
1. a comet is an icy small solar system body that when passing close to the Sun warms and begins to release gas has a process called outgassing. this produces a visible atmosphere, and sometimes also a tail.
2. comets have two sources. long period comets originate from the Oort cloud. short period comets originate from the Kuiper belt
The explanation lies in how the stomata works. They regulate any gasses that passes trough them. When the temperature is too hot, it will close to conserve water vapor but this will block CO2 coming in also. Therefor plants don't want to have their stomata closed all the time nor opened all the time. Sunlight hits the top surface of leaves. If many stomata were to be located on the top, the plant would loose much of its water and when the stomata closes to conserve water, it won't get as much CO2. Therefor for most plants, the stomata stay on the bottom where the temperature is a bit cooler. Also it is protected from the wind since wind can cause evaporation of water. I hope this Helps c:
Answer:
False. Prokaryotic cells can still perform photosynthesis, but it occurs on the membrane instead.
Explanation:
Answer:
The practice of growing a series of different types of crops in the same area across a sequence of growing seasons.
This question is unfortunately incomplete. The burning of coal containing sulfur can lead to the release of sulfur oxide compounds to the atmosphere. These compounds <span>combine with atmospheric water to form sulphuric acid. Sulphuric acid lowers the pH of atmospheric water vapour, and during rainfall events, precipitated rainfall will be of a low pH (acid rain).</span>
