Answer:
Light was a limiting factor for photosynthesis under the given conditions. Light is required for photosynthesis.
Explanation:
According to Blackman's principle of limiting factors, the rate of photosynthesis is regulated by the factor which is present below the minimal value. Photosynthesis is regulated by many factors such as CO2 concentration, temperature, light intensity, etc. However, under particular conditions, the factor present below the minimum levels regulate its rate.
In the experiment, when the light intensity was present below its minimum levels, an increase in the light intensity increased the rate of photosynthesis. Here, light intensity was the limiting factor and no other factors such as CO2 or temperature would affect the rate of photosynthesis.
Once the light intensity reaches its optimal levels, other factors become limiting and there is no further increase in the rate of photosynthesis by increasing the light intensity.
Yes, water is a polar molecule because the Electrons are NOT shared EQUALLY
Answer:
c silent mutation
Explanation:
The given mutation changes the genetic code "GGC" to "GGA". According to the genetic code table, both "GGC" and "GGA" code for glycine. Since both mutated and normal codon code for the same amino acid, that is glycine, the mutation would not have any effect on the function of the gene.
The point mutation that does not affect the function of a gene is called a silent mutation. Hence, the given example represents the silent mutation.
If sodium ions are outside of a cell, they will tend to move into the cell based on both their concentration gradient and the voltage across the membrane (the more negative charge on the inside of the membrane). So cells pump out the extra ions.
