The 4 major bases that make up DNA would be Adenine, Thymine, Guanine and Cytosine. The pyrimidines which are Cytosine and Thymine are structurally similar to each other, as they both only contain a single Carbon containing ring. While Purines, which are Adenine and Guanine, contain 2 chemically bonded carbon containing rings with each other.
As per the base pairing in DNA. Adeline always pairs with Thymine with 2 hydrogen bonds, while Guanine pairs with cytosine with 3 hydrogen bonds.
The base pair that is not found in RNA would be Thymine, instead another pyrimidine, which is uracil is used instead for processes dealing with RNA molecules.
Answer: the absorption of water by the roots
Explanation:
Evaporation of water through the leaves is known as transpiration, and it occurs readily only when environmental conditions such as humidity is high.
On the other hand, the absorption of water by root hairs which is then conducted by the xylem vessels up the stem to various parts of the plant is a important process that determines how water move through a plant to ensure cellular processes such as photosynthesis, respiration etc takes place.
Thus, the absorption of water by the roots plays a much more important role in the movement of water in a plant
Answer
In photosynthesis, water, carbon dioxide, ATP, and NADPH are reactants. RuBP and oxygen are products. In photosynthesis, water and carbon dioxide are reactants. GA3P and oxygen are products.

Answer:
Mutualism: It is a type of symbiotic relationship between two organisms in which both the organisms gets benefits to each other.
For example, in leguminous plants a bacteria is present in the roots of the plants and make symbiotic relationships with each other. In this relationship, plant provides habitat and food to the bacteria and in return the bacteria fixes atmospheric nitrogen for the plant and both get benefit.
