Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
B. is the correct answer because not all genes are actively coding,RNA is not code for protein synthesis, also DNA does not contain a number of segments that code for specific proteins.
The number of molecules in some water isn't affected by changing its temperature. But to know if you have the same number of molecules in two water samples, you need to compare their masses, not their volumes. When you heat some cool water, it expands. (When you slightly warm some ice-cold water, it contracts a little, but let's keep this simple.) So hot water takes up more space than cold water. The amount of space something takes up is called volume. If you were to have 2 cups of water, one of hot water and one of cold water with equal volumes, the cold water would have more molecules.
<span>Hot and cold water are made of the same type of molecules. Each molecule has one oxygen and two hydrogen atoms. The difference between them is the speed of the molecules jiggling around. </span>
All of the above, hope this helps!
Answer:
True
Explanation:
The proliferation of phytoplankton (microalgae) may decrease the visibility which causes oxygen (O2) depletion because they consume important amounts of O2 during the night and cloudy days. An algal bloom refers to the sudden increase in the population of algae in water bodies. These algae consume O2 and block the sunlight from underwater plants. As the algae die and decompose, O2 concentration in the water decreases, and, in consequence, most aquatic life that depends on oxygen dies.
