4. Using a complete sentence, state what would most likely happen to the production of oxygen by duckweed plants if the intensit

y and duration of exposure to light were increased.​

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.

Genetic variation in bacterial populations cannot result from
zmey [24]

Answer:

Meiosis

Explanation:

Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.

Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.

Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.

Within a given species, which two types of cells have the equivalent amounts of dna?
kiruha [24]
The original question has a set of choices. This is within the context of cell division. The choices are:

A. A cell in G1 of interphase and a cell in G2 of interphase
B. A cell in G1 of interphase and a cell immediately after the completion of meiosis II
C. A cell in G1 of interphase and a cell in metaphase II of meiosis
D. A cell in G2 of interphase and a cell in metaphase II of meiosis
<span>E. None of the above.
</span>
The correct answer is C. A cell in G1 is diploid and the cell in meiosis II is haploid but the amount of DNA still equivalent as each chromosome in the haploid cell consists of two chromatids. G2 cells already had been through the S phase therefore the genetic material is already doubled. A cell immediately after meiosis II has half the genetic material.
