Explanation:
- The gardener plants only seeds of last year's largest vegetables because he knows that these seeds grows larger like their previous generation.
- For more profit he plants only them .

Answer:</h2>
Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h2>
Explanation:</h2>
Mutation assumes a significant job in evolution. A definitive wellspring of all hereditary variety is a mutation. It is significant as the initial step of development since it makes another DNA succession for specific quality, making another allele.
Recombination additionally can make another DNA succession (another allele) for a particular quality through intragenic recombination. Mutation going about as a developmental power independent from anyone else can possibly cause huge changes in allele frequencies over exceptionally significant stretches of time.
Answer:
the answer for this is B.
Answer:
Cell sap is a fluid found in the vacuoles (small cavities) of the living cell; it contains variable amounts of food and waste materials, inorganic salts, and nitrogenous compounds. Phloem, or sieve-tube, sap is the fluid carrying sugar from leaves to other parts of the plant in the summer.

Answer:
The main purpose of light dependent reactions of photosynthesis is to generate ATP and NADPH.
Explanation:
Photosynthesis consist of two reactions 1 light reaction 2 dark reaction .The light reaction occur in the thylaKoid of Grana to produce Adenosine tri phosphate (ATP) and NADPH
Role of ATP
ATP is an energy rich molecule which undergo hydrolysis to provide energy for Carbon di oxide fixation during dark reaction. The carbon di oxide fixation is very much important to produce glucose.
Role of NADPH
NADPH act as reducing equivalent that carry out the reduction of phosphoglyceric acid formed in the first step of light independent reaction to generate phosphoglyceraldehyde(PGALD). Some PGALD then undergo various enzymatic reaction to form glucose and rest are utilized to regenerate ribulose bis phosphate(RUBP).
