Carbon dioxide is released by animals.
Answer:
All of the above
Explanation:
When we talk about soil quality we talk about soil components. The chemical composition is an active part of the soil components because it has Nitrogen, Ca+, Oxygen and other molecules that affects the interaction among the soil and its environment. The living organisms interacts with the molecules in the soil changing constantly their concentrations that modify the pH and the soil quality. All of these changes accumulation tell us how the soil has changed through the time, also can give us information to predict how soil will change, this is known as history of the soil.
To summarize the chemical composition affects directly the soil quality, the history of the soil are all the changes that it has suffer in its composition through time so it define the actual soil quality and the living organisms interact with the chemical composition changing it constantly and giving new qualities to the soil.
Explanation:
Latent prints are formed when the body’s natural oils and sweat on the skin are deposited onto another surface. For example if you put your thumb on your glass you will see that the oils will put your fingerprint there
Answer:
The statement is true
Explanation:
The phosphate group in the sugar-phosphate backbone contains a negative charge on the oxygen atom which gives the DNA its overall negative charge. This negative charge on DNA in helpful in the coiling or packaging of DNA around the positively charges histone protein.
This negative charge property of DNA is used in electrophoresis to separate the DNA according to their charge and size. In electrophoresis, the negatively charged DNA is attracted towards positive poles and is separated according to their charge and size. Therefore the statement is true.
