Further explanation
greenhouse is a building that is formed from a glass structure. greenhouse is widely used by farmers whose countries have various climates. The temperature in the greenhouse will feel warm even though it was during winter. the way greenhouses work by capturing sunlight and sunlight is trapped inside the building so that the air remains warm.
The greenhouse effect is another term to describe the earth as having that effect where the sun's heat is trapped by the earth's atmosphere. gases in the atmosphere can hold heat from the sun's rays so that the sun's heat is trapped in the earth's atmosphere.
In general, the understanding of the greenhouse effect is the increase in earth's temperature caused by changes in composition, which is found in the atmosphere. That causes the sun's rays to remain on earth, and unfortunately not reflected perfectly to get out of the atmosphere.
the beginning of the greenhouse effect due to sunlight that has been reflected by various objects that exist in the layers of the earth. the process of this greenhouse effect begins when the sun emits its light in the form of ultraviolet radiation to the earth. These rays will be received by the earth and then reflected back in the form of infrared.

Answer:
Genetic drift reduces the size of gene pool of the population.
Explanation:
Genetic drift is any chance event that results in changes in the allele frequency of a population. The event either fixes an allele on the particular locus or makes the population to lose that allele.
Hence, genetic drift changes the genetic frequency by removal of a particular allele or by fixing it in the gene pool. Both conditions lead to reduced genetic variations in the population. And since genetic drift reduces the size of the population, the gene pool of the population would also shrink due to loss of alleles from it.
Answer:
Organisms
Explanation:
When we speak of geological time, we refer to a time scale that is usually measured in millions or even billions of years, such as the classification of geological ages and their respective periods. Geological time is a scale obtained from the relative dating of the rocks, either by observing the marks of the events recorded in them, either by the order of superposition of the sedimentary layers or by the fossils they contain, or even by the absolute dating of the rocks, through calculating the rate of disintegration of a radioactive isotope. Radiometric dating of rocks from the Moon and meteorites gave an approximate age of the planet Earth in 4.5 billion years. In addition, geological time is divided into units based on the types of organisms.
Geologic time is divided into units based upon types fossils found in each area .
I hope that's help !
