Answer: In plants, they need to move mineral ions from the soil into the roots. Mineral ions are more concentrated in the cytoplasm of plant cells than in soil water or dillute.

Answer:
Selectivity in choosing a mates
Geographic barriers separating subpopulations.
Explanation:
Selectivity in choosing a mates is a factor in which individuals can mate with each other. Some individuals tend to choose a sexual mates that posses some traits or characteristics that attract them to each other and because of the observable character, similar individuals attracted to each other mates.
Geographic barriers separating subpopulations is another factor that make similar organism or individuals to mates.
When there is geographic separations or demarcation between individuals in a species and they are separated from other subpopulations .. They tend to mate with each other in the same geographic location and cannot mate with other subpopulations that is outside their own geographic location. These is common in animals.
Answer:
a) guanine to guanosine monophosphate (GMP)
Explanation:
- Hypoxanthine-guanine phosphoribosyl transferase (HGPRT) is a transferase enzyme which is responsible for the conversion of guanine to guanosine monophosphate (GMP) and of hypoxanthine to inosine monophosphate.
- The primary function of HGPRT to salvage the purines from the DNA that has been degraded and thus reintroduce the purines into the purine synthetic pathway.
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.
