You have to employ deductive reasoning to answer this question.
Do sea walls protect land from erosion?
Do limits on clear cutting protect land from erosion?
Do cut and burn methods conserve land by enriching the soil?
How would rain water harvesting contribute to the conservation of land?
Downwelling topic should be read by Pedro to understand the phenomenon.
Explanation:
The sinking and accumulation of high density material beneath the material of low density is the process of Downwelling. One such example is of- the saline water lies beneath the freshwater. It takes place in the oceanic anti-cyclonic areas where surface convergence is created.
It causes ventilation in oceans and helps in facilitating aerobic respiration in different organisms by bringing surface oxygen dissolved in water. This condition is the reason behind the survival of aerobic organism under water.
Answer:
The high transmittance (low absorption) reading indicates that chlorophyll absorbs very little green light.
The low transmittance (high absorption) reading indicates that chlorophyll absorbs most blue light
Explanation:
- The galvanometer is a device which is used for measuring the electric current.
- In a spectrophotometer the galvanometer is attached to indicated the amount of light that is getting transmitted through a sample.
- If the amount of light that is getting transmitted from the sample is more, the reading of the galvanometer would be higher and if less light is transmitted the reading of the galvanometer would be less.
- Further, the transmittance of a light is inversely proportional to the absorption, that is if the absorption would be low transmittance would be high and vice versa.
- Therefore, when the chlorophyll is exposed to green light, the transmittance is high and this implies that the absorption of green light would be less.
- Similarly, when the chlorophyll is exposed to blue light, a low transmittance indicates a higher absorption of blue light by chlorophyll.
Answer:
The correct answer is "Charles Darwin and Alfred Russel Wallace".
Explanation:
Charles Darwin and Alfred Russel Wallace are two of the most prominent scientists regarding evolutionary biology. In 1859, the famous book "The origin of the species" by Charles Darwin explained that species develop new traits along several generations, where the traits that are advantageous for the species remain. Alfred Russel Wallace, as well as Charles Darwin, was a naturalist that performed many research expeditions. These two men shared many letters and both concluded that variation of traits might provide better odds of survival in certain environments, where natural selection works as a selector of traits.
