Answer:
The correct answer is - O and 6.9; 7.1 and 14
Explanation:
A measuring scale that tells about the acidity or basicity or alkaline nature of a particular object or solution is possible with the help of a pH scale that measures how acidic or basic a solution or object is.
It ranges between 0 to 14. pH less than 7 or ranging from 0.0 to 6.9 is acidic and more than 7 or from 7.1 to 14.0 is basic or alkaline in nature. A measure of the relative amount of H+ ion and OH- ions in water is pH.
Answer:
mitochondria because it provides the cell with energy
Answer:
All are true of the movement of Earth's atmosphere except :
d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.
Explanation:
- When gases heat up, their volume increases and density decrease.
- A decrease in density causes a substance to become lighter.
- Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
- So, it will move up.
- The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
- Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.

Explanation:
as more and more humans are born they will need more and more food homes and many other things, but they will eventualy run out.
Please give me brainly (if it is correct which i am certain it is)
Answer:
The correct answer is A. Substrate-level phosphorylation
Explanation:
During the substrate-level phosphorylation, phosphoryl group is directly added to ADP or GDP to form ATP or GTP from phosphorylated intermediate rather than from inorganic phosphate like in case of oxidative phosphorylation.
So in glycolysis 4 ATP are produced by substrate-level phosphorylation. Apart from the 4 ATP, 2NADH are also produced during the glycolysis which is used during the oxidative phosphorylation and produce 4-6 ATP.
So ATP made during glycolysis is generated by substrate-level phosphorylation as ATP is produced by direct addition of phosphoryl group from intermediates.
