A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.
Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.
Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).
Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.
C02 + H20 → C6H1206 + O2+ H20.
(carbondioxide) + (Water) Chlorophyll (glucose) +(oxygen)+ (water)
and
enzymes .
This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.
The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is the source of oxygen seen above.
4 H20→ 4H+ + 4e- + 02.
The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.
Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.
B.
The cell wall of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .
<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains, monomers of glucose in small units linked to one another by bonds.
C
Vacuole helps in plant turgidity needed for uprightness. when filled with water provides turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity helps the plants to maintain resistance to external pressure and therefore resist the effects of gravity.
