Water diffuses into the skin via sweat ducts which alters the electrolyte balance. electrolytes can be salts like sodium and potassium. This alters the stability of neurons causing blood vessels to constrict therefore decreasing the amount of fluid in the fingers which would normally give the skin tension. The decrease causes wrinkles.
Answer:
See explanation
Explanation:
According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.
During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.
This variation may also lead to the observation of new phenotypes in the population.
Answer:
Changes in the environment may leave individuals less well adapted to compete successfully for resources such as food, water and mates. Sometimes an entire species may become unable to compete successfully and reproduce. These problems can lead to extinction.
