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-.
Tretinoin is a naturally occurring metabolite of retinol in the retinoid class, including natural and synthetic analogues. It is the acid form of vitamin AIt acts on cell growth and differentiation. Its main use is the treatment against acne thanks to its keratolytic and anti-inflammatory properties. Tretinoin is also used in the treatment of acute myeloid leukaemia type 3 (AML 3).
SIDE EFFECTS:
Among the expected effects, side effects may occur. Signs of an allergic reaction include: hives, difficulty breathing, swelling of the face, lips, tongue or throat;
It should be known that tretinoin can make you more sensitive to the sun, so use sunscreen every day, and wear protective clothing outdoors.
Cholesterol and triglycerides should be done before and during treatment because this drug could increase their values
Some patient with leukaemia treated by tretinoin has suffered from The syndrome of retinoic acid which is characterized by fever, dyspnea, acute respiratory distress...

All the emissions go in to the atmosphere and that causes the ozone layer to open up more and let radiation in. the effects are that they pollute the wild life around it and the people that have to dig it up destroy the natural habitat
Answer:
It reflects the amount of force an object exerts
Explanation:
A newton is a unit of force that will accelerate one kilogram of mass one meter per second squared.
