how does water role in photosynthesis explain increased biological productivity in area of heavy precipitation​
s344n2d4d5 [400]

Answer:

Photosynthesis takes in energy from the sun, CO2 and H2O and produces Glucose(don't know formula), O2 and H2O. This means the water is needed for the reaction but isn't transformed. This means that in areas with greater average rainfall, plants generally grow faster.

Please help with my recent questions if this helped. :)

hodyreva [135]
<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>

Allushta [10]
1. The answer is "<span>the energy required to start the reaction".

</span>This energy is called as activation energy of the reaction. If the activation energy is high, reaction is slow. Enzymes help to carry out the reaction by a new path by reducing the activation energy. But the energy of reactants and the products remain as same as without enzyme.

2. The answer is "reaction in cells would be too slow to sustain life<span>".

</span>If the activation energy is very high for the reaction, then that reaction will be very slow and will require more time<span> to complete the reaction. Then survival is very low. Hence, the roll of enzymes is very important to sustain life.</span>

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reprod
Lunna [17]

Answer:

Reproductive cells have half the amount of chromosomes than body cells

Explanation:

I think that you are talking about body cells when you say "most cells in an organism." If that is the case, then the reproductive cells, sperm and egg cells, have half the amount of chromosome than body cells.

For example: Human body cells have 46 chromosomes. Human reproductive cells has 23 chromosomes.

In sexual reproduction, each parent gives 1/2 of a full set of chromosomes to create the full set needed for an organism.
