egoroff_w [7]

Answer:

See the answer below

Explanation:

<em>If the intensity and duration of exposure to light are increased for a duckweed plant, the rate of photosynthesis would increase and this would lead to an increase in the amount of oxygen produced.</em>

From the equation of photosynthesis:

6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2

the more the rate of photosynthesis, the more the amount of oxygen produced. Also, an increase in the intensity of light generally increases the rate of photosynthesis (and oxygen production) provided that other reactants can catch up. The rate of photosynthesis would become limited by the reactant that is available in the lowest quantity.

When a population is split into smaller groups, why do these groups develop different traits?
aniked [119]

Answer:

C. Forces like natural selection and genetic drift affect the genes of the two subgroups diffidently.

Explanation:

For example, a group of finches separate do to something out of the blue. Over time, one group may evolve and develop traits that make them different from the original group, like larger or smaller beaks. The genetic drift comes into play since the genes that affect the physical and mental behaviors are being created or switched around.
