A<span>ctive transport because passive transport does not as well as diffusion.
</span>
Answer:
The correct answer is it occurs naturally by diffusion.
Explanation:
Diffusion is one of the most important passive transport mechanism which helps in the movement of small molecules and gases across the plasma membrane down their concentration gradient.
In simple words diffusion deals with the transport of small molecules and gases from the region of high concentration to the low concentration region untill the contration of both the regions become equal.
Ultraviolet, or UV, rays ,these are the rays that can cause sun damage to a person's skin in the form of sunburn. While a person cannot detect the sun's UV rays, he or she can detect the infrared rays via the sensation of heat.
Gamma rays - these are most often found in the core of the sun, during fusion. These rays lose frequency as they move towards the surface.
X-rays -
X-rays are emitted by the sun during solar flares.
Visible light -
visible light are radiation waves that are in the frequency range easily seen by the naked eye. Different wavelengths in the visible light spectrum make up different colors.
Microwaves -
microwave radiation waves emitted by the sun are primarily absorbed by the Earth's atmosphere.
Radio waves -
these waves have the longest wavelengths, and the sun is the brightest source of radio waves.
A nucleophilic addition-elimination reaction between the carboxylic group and the amino group bonds the amino acids together.
Cells exposed to environmental factors known to cause mutations in genetic material will <u>become cancer cells</u>
<u>Explanation:</u>
Environmental factors like radiation and high concentration of chemicals are among the factors that cause mutation in the genetic material. Internal genetic changes causes mutation in the genetic material, the DNA there are many chances of the mutated gene to convert into an Oncogene.
An Oncogene is a genetically mutated gene which causes tumor. The mutated gene causes proliferation of cells. More than 90% of the cancer is caused by the carcinogenic substances present in the environment.
