Answer: Basically groundwater is created when precipitation seeps into the soil, so if there was a drought and it hardly rained, the groundwater could be considered an unrenewable resource until it rained again.
Explanation:
Answer:
C. 0.120
Explanation:
Assortative mating by phenotype means that individuals with similar phenotypes mate with one another more frequently than would be expected under a random mating pattern. Assortative mating can increase genetic relatedness within a population.
The answer is C. 0.120 because in assortative mating, the allele frequency does not change as it is non-random mating and mates are chosen based on their phenotypes.
Answer:
b. grasshopper effect
Explanation:
Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.
When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.
Answer:
The correct option would be A. It drops quickly to zero once the temperature goes below freezing.
Carrying capacity is defined as the number of organisms (animals, plants, crops, or birds) a region can support without getting degraded.
The temperature in the northern New York forest can drop below freezing during winters. Due to this, insects either migrate the place or spend winters as eggs, larvae, nymphs, or pupae.
It resulted in the unavailability of insects or food for insectivorous birds due to which carrying capacity of a region quickly drops to zero.
Answer:
Mutation. A mistake made while DNA copies which causes changes in DNA
