Answer:
inbreeding
genetic bottleneck
founder effect
Explanation:
These different types of genetic drift change the allelic frequencies in a population through chance.
Inbreeding, genetic drift, restricted gene flow, and small population size all contribute to a reduction in genetic diversity. Fragmented and threatened populations are typically exposed to these conditions, which is likely to increase their risk of extinction

Which of the following is correct about mutations and genetic variation?
a
It must be present in a population before natural selection can act upon the population.
b
It arises in response to changes in the environment.
c
It tends to be reduced when diploid organisms produce gametes and reproduce.
d
It is created by the direct action of natural selection.
It arising in response to changes in the environment is correct about mutations and genetic variation.
What is Genetic variation?This can be defined as difference in DNA or characteristics in organisms. Meiosis brings about variation in organisms during reproduction.
Mutations and genetic variation arises in response to environmental changes thereby making option B the most appropriate choice.

How does carbon dioxide affect the earth and Its atmosphere?
Increasing carbon dioxide in the earth's atmosphere is responsible for the greenhouse effect.
Decreasing carbon dioxide in the earth's atmosphere is responsible for the increase in sea levels.
Increasing carbon dioxide in the earth's atmosphere reduces the temperature on the earth.
Decreasing carbon dioxide in the earth's atmosphere is responsible for melting the polar ice caps.
Answer:
Increasing carbon dioxide in the earth's atmosphere is responsible for the greenhouse effect.
Explanation:
Carbon dioxide is a greenhouse gas. Greenhouse gases trap heat in the Earth's atmosphere which causes the earth to warm up. This is called the greenhouse effect.
Please need answers quick Explain how soil composition is affected by environmental factors.
Answer:
Explanation:
Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms. The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place.
According to the leading theory today, how does the composition of the inner and outer core cause Earth's magnetic field?
Answer:
electric things
Explanation:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core these convection currents are caused by heat escaping from the core a natural process called a geodynamo.
The composition of the inner and outer core cause Earth's magnetic field by a process called geo dynamo
What is Geo dynamo?Geo dynamo is the process where electric current generates the magnetic field due to convection currents where the inner and outer cores are iron and nickelThese convection currents are caused by heat escaping from the core. the inner and outer cores are iron and nickel spins and generate the earth’s magnetic field.
