Answer:
a) genetic drift - yes
b) Natural selection - yes
c) Gene flow - yes
d) Mutation - yes
Explanation:
factor that alter the allele frequencies are
a) genetic drift - yes
b) Natural selection - yes
c) Gene flow - yes
d) Mutation - yes
Genetic drift - Alter occur due to sampling error or selecting error. in this some error occur while deciding for the allele for the next generation.
Natural selection - it is due to large number of one type of allele in the population
Gene flow - it alter because of migration of allele among the populations.
Mutation - it is strong for introduction of new alleles in the population
Answer:
Wastewater treatment The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
Explanation:
Answer:
C) releases oxygen into the air
Explanation:
Stomata are the minute openings present in the epidermis of leaves. Plant open stomata to take in carbon dioxide gas from the air which in turn is fixed into organic compounds during the process of photosynthesis. Oxygen gas is the by-product of photosynthesis. Plants release oxygen from stomata into the air. Therefore, dermal tissues in leaves have stomata and one of their functions is to release oxygen into the air.
