Answer:
Two cell divisions after DNA replication
Explanation:
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.
Answer:
Genetic drift
Explanation:
Genetic drift is defined as the random change in allelic frequencies from one generation to the other.
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
Clouds and Strom
The troposphere is the most minimal layer of Earth's environment that is closest to humans , and is likewise where almost all climate conditions happen. It contains roughly 75% of the climate's mass and 99% of the aggregate mass of water vapor and pressurized weather elements occur
B. Habitat Destruction
This is because the wading birds' wetland habitat was destroyed by the housing developers. Since the wetland was drained, their habitat is no longer available to them for nesting or hunting.
Diffrent type of biome because we do not live in a rainforest or desert
