<span>This would be a positive reinforcer. These are things like rewards and bonuses that will cause the subject to want to continue the rewarded behavior. The reinforcer does not need to be financial or even tangible. Positive comments and approval can be reinforcers that strengthen associated behaviors.</span>
Groundwater is defined as water that is found beneath the surface of the earth in conditions of 100 percent saturation (if is less than 100 percent saturation,then the water is considered soil moisture).Ninety-eight percent of earth’s available fresh water is groundwater
Answer:
The correct answer would be - biological species concept.
Explanation:
The biological species concept is a concept of speciation or how a species forms in nature. According to this, a species is the group of the population that can naturally or potentially interbreed with each other, not on the basis of their physical similarities or habitats.
The physical appearance could be useful as recognizing a species but not defining it. As neanderthals show very little or no gene flow with a modern human it means they do not belong to the same species as modern homo sapiens.
Thus, the correct answer is- biological species concept.
Answer:
1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)
2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).
3. A and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)
4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.
5. B (Mutations are the main source of alleles)
