Explanation:
Genetic variation is the variation in the DNA sequence in the genome of an organisms. Organisms of a species have similar characteristics but they are not identical due to genetic variation. Genetic variation is important in the survival and the adaptability of a given species of organism. Therefore, in this case lack of genetic variation necessary to adapt to change in the environment will lead to extinction of the fish species that lacks the variation.
28. Part A.
A nucleic has a sugar group, a phosphate group, and nitrogenous base. A carbohydrate only has the sugar group units.
Part B
Nucleic acids make up the DNA and RNA which contain the genetic material for life.
Carbohydrates are used to provide energy to the cells.
Part C
Because all life require energy and this energy can be obtained from carbohydrates.

Answer:
The precise definition of pH is "the negative common logarithm of the activity of hydrogen ion in solution". For practical purposes, the activity is approximated as concentration in moles/L: pH = - log 10 ([H+]) .
Explanation:
Answer:
A. A thick, waxy covering to prevent evaporation.
Explanation:
Because the desert is usually dry and hot, plant that live in these ecosystems need to adapt to the environment to prevent the loss of water. Water escapes from plants through their leaves as a result of photosynthesis. Desert plants have special adaptations to at least reduce the loss of water and one of them is the thick waxy covering of the leaves to seal in the water.
