Answer:
Sensory transduction.
Explanation:
Sensory transduction may be defined as the process by which sensory stimulus are transformed in the body. The receptor cell is mainly involved in the sensory transduction process.
The sensory receptor cell like a light or an odor is converted into the electrical signal by the process of signal transduction. The information is then conveyed to the nervous system in the form of electrical signals.
Thus, the correct answer is signal transduction.
Answer:
Species a and c
Explanation:
The species c, was more closely related to species a than species b was. This is because species a and c just recently evolved into different species in evolutionary history.
1. is (A) because mouse and deer are not in the same ecosystem.
2.is (D) because both antelope and domestic cattle do not affect each other.
3. is (B) because food is important factor.
4.is (C) because without home it is not possible to adapt in an ecosystem.
The answer is; the melanin in darkly pigmented skin protects DNA from UV radiation, and UV radiation can cause skin cancer
In Africa, due to its equatorial latitude location, receives direct sunlight at more or less 90 degrees most of the year. These highly concentrated rays increase the UV radiation exposure that can cause damage to cell DNA. Selection pressure, therefore, favored individuals with high melanin concentrations that protect against UV. Therefore population evolved towards high melanin densities in the skin.
Be there for them and let them know they're not alone.
