Answer:
B
Explanation:
Stratosphere,absorbs rays of damaging ultraviolet light from the sun
Answer:
We could use up all of them right away and not have the resources for humans and animals to survive.
Explanation:
Right now, we are using our natural resources at a consistent rate. We sometimes use to many of them in one day. If we continue using up our natural resources at the rate we are right now. We may not have the necessary resources to survive in about 10-20 years.
Hope this helps!
Answer:
Organelle 1
Explanation:
Organelle 1 is the nucleus which stores genetic material such as the xx or xy chromosomes which contain the information for what gender a person is.
Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.
