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.
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Answer:
The correct answer is: B) codominance.
Explanation:
<u>Codominance is a type of inheritance pattern that describes the relationship of two variations of the same gene</u>: this means that in an individual, its two alleles manifest in the phenotype.
If a sunflower has both blue AND yellow speckles, it means that the two possible alleles are in a relationship, which makes these alleles CODOMINANT.
Plants take in Carbon (Co2) in order to produce Oxygen for us to breathe and live.
This is why fertilizers do not need or use Carbon.
I hope this helps you a lot.
Answer:
Phosphofructokinase will be activated
Explanation:
Phosphofructokinase (PFK-1) is an enzyme of glycolysis that catalyzes the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate. The enzyme uses ATP as a phosphate group donor for this phosphorylation. It is a regulatory enzyme and the reaction catalyzed by it is irreversible. The activity of PFK-1 is increased whenever the cell’s ATP supply is depleted or when the ATP breakdown products, ADP and AMP, are in excess.
