Polar ice cap

Explanation:

The polar ice cap is an area on the earth that extends from 66.5° north and south of the equator to the poles.

The polar ice cap is an area of very low temperature and the surface is mostly covered by ice.

  • The vast polar ice caps the earth's northern and southern limits.
  • This is the region of the Arctic and Antarctic circle.
  • This region receives diffused solar radiation from the sun.
  • This is why they rarely warm up.

How do the colors of light affect photosynthesis? Which color was most efficient, medium and least?
Virty [35]

Answer:

blue is the most efficient while green is the least efficient  

Explanation:

It is well known that different photosynthetic pigments can absorb light at different wavelengths. Thus, the amount of light absorbed during photosynthesis depends on the color of the source light. The leaves have green color because chlorophyll is a photosynthetic pigment that absorbs light at all wavelengths and reflects green light. The best wavelengths are those at 430–450 nm (blue range) and 600–700 nm (red range), thereby photosynthesis is most efficient when plants are illuminated by light sources that emit blue and red lights. Moreover, sources that emit light at the green wavelength are least efficient for photosynthesis.

What would be the most effective method of reducing the incidence of blood flukes in a human population?
o-na [289]

Answer:

By the use of uncontaminated water

Explanation:

Blood flukes are flatworms that are parasitic in nature. These are also called schistosomes.

If we consider the mode of transmission of the parasites to humans, we find that their transmission occurs in the following conditions -

  • These parasites enter the human body when a person is swimming in contaminated water.
  • They can also infect the human body if the person drinks contaminated water or eats food that have been washed with the contaminated water.

Thus it becomes clear that contaminated water is the main source of infection of blood flukes so using uncontaminated water and avoiding to be in contact with contaminated water will reduce the incidence of blood flukes in human population.
