Answer:
73%
Explanation:
Given: 27%
To find: Percentage of nitrogenous bases are cytosine
Solve: ×
Firstly, divide 100% by thymine and cytosine
= 50
Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100
100 - 27 = 73
So, the percentage of nitrogenous bases are cytosine 73%
Answer:
The correct answer will be- releases energy from chemical bonds of molecules such as glucose
Explanation:
The cellular respiration is the process which is associated with the slow oxidation of the food molecule which provides energy molecule.
The most favoured food molecule or the substrate which undergoes cellular respiration is the glucose which is broken down to release the energy molecules like ATP.
The process of cellular respiration takes place in four stages: Glycolysis, Pyruvate decarboxylation, Citric acid cycle and the electron transport chain. The glucose molecule is broken down to form various products through glycolysis.
Thus, Option-B is the correct answer.
The answer would be:
Passive transport
Active transport
Why?
There are two ways molecules can move across membranes within the cell. What makes the two different is the use of energy.
PASSIVE transport is the movement of molecules DOWN the concentration gradient. The molecules move from areas of higher concentration to lower concentration. This does nor require energy. Comparing it to the scenario, the child starts from a higher area and ends at a lower area. Going down a slide does not take energy. The child simply goes down it.
When you talk about the child going UP a slide, think ACTIVE transport. Unlike passive transport, active transport requires energy, because the molecules move AGAINST the concentration gradient. The movement of molecules in this type of transport is the opposite, it goes from lower areas of concentration to higher areas of concentration.
Hopefully, this has been educational for you and was able to help you understand the difference between the two.
