Answer:
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.
Explanation:
Answer: The bonds that hold atoms together to form molecules are called covalent bonds. They are pretty tough and not easily made or broken apart. It takes energy to make the bonds and energy is released when the bonds are broken.

Answer:. have chloroplasts and a cell wall
Explanation:All living organisms are made up of cells.some organism are made up of one cell (Unicellular) and other organism are made up of many cells(multicellular).
Cells are made up of organelles and the organelles present in a cell differ in animals cells and plant cells.
A feature that animals cells have which plant cell do not have is the presence of centrioles.
Features that plant cell have which animals cells do not have are the presence of chloroplast ,vacuole and cell walls.
Animals do not produce their food but plants do.Green Plants produce their food through chloroplast,which contains chlorophyll.
Plants has cells walls which is rigid and made up of cellulose,lignin and pectin.this rigid structure of the cell wall contributes to the rigidity of plants stems and roots.
Option A is incorrect because plant and animal cells have mitochondria.
Option B is incorrect because plants cells have both plasma membrane and cell walls.the cell wall surrounds the plasma membrane.
Option C is incorrect because plants contains Golgi apparatus and vacuole
