Answer:
The human eye is the prime organ of the body, which associates with the photons of light and allows one to see various things. The unique cells found in retina, which does activity of seeing are cones and rods cells. Rods help to see in dim light vision, while on the other hand, cone cells are unique in recognizing different colors.
These cells comprise photoreceptor proteins that help in trapping photons at particular wavelength. Mutation in the gene encrypting for these proteins results in permanent or temporary vision issues. The extremity of defects relies upon the degree to which mutation takes place.
The mutation in rod cells photoreceptor proteins leads to night blindness and retinitis pigmentosa. Retinitis pigmentosa refers to an inherited disorder that takes place because of early loss of rod cell, which destructs retina. On the other hand, night blindness does not mean complete blindness night, however, inadequate tendency to see in low light.
Identically, the mutation in the cone cell also results in vision issues, known as red color blindness and tritanopia. Tritanopia refers to a kind of color blindness, which originates because of insensitivity of blue receiving protein gene towards blue light. On the other hand, red color blindness refers to insensitivity of red receiving cone cells in captivating long-wavelength photons.
Answer:
V≈904.78cm³
Explanation:
The volume of a sphere with a diameter of 12 centimeters is 904.78cm³.
Formulas: V=4/3πr³ and d=2r
V=1/6πd³=1/6·π·12³≈904.77868cm³
If two species of tertiary consumers are living together in a community, there build a competition between them.
Tertiary consumers feed on primary and secondary consumers and there is no one to feed on them hence named as Apex consumers.
If two consumer species are living together, there will be limited amount of food source which will give birth to competition and which might to lead extinction of one specie.
