Answer:
C. 275 nm
Explanation:
At 275 nm of ultraviolet wavelengths causes mutation in a skin cell because at 275 nm of wavelength, maximum DNA Copying Errors occur in the cells that leads to mutation in the cell. A mutation is a kind of change that occurs in the DNA, due to two reasons, due to mistakes that is occur when the DNA is copied or as the result of environmental factors such as ultraviolet radiations.

Answer:
Key molecules that contain carbon include proteins, nucleic acids, carbohydrates and lipids. Carbon is an integral part of many biological processes, including reproduction, photosynthesis and respiration.

Explanation:
Shape, Color, Smell and long Stamens are the feature of plant who helps in pollination.
Explanation:
The color plays vital role in pollination. It attracts the birds as well as insects. Some flower has ultraviolet mark which can be seen by only insects not by human eyes. Flower has also proper landing shape which force the insects to brush against anthers and stigmas.
The scent of flower is another important feature which is helpful in pollination. Insects and birds attract due to their scent and help in pollination. Some flower doesn’t have color and scent but they have long stamens. These flowers are pollinated by wind.
