Answer:
Explanation:
1. Describe two effects of insecticide use on the forest ecosystem other than the intended reduction of moths to protect the trees.
1. Insecticides when sprayed on a certain areas or spots can be blown by the wind to other areas or flow with rain water into nearby streams or local water bodies or seep through the soil into ground water. This is called indirect application or secondary poisoning,
2. Insecticides can affect the food chain because they reduce the biomass of primary consumers and there is is less food available to secondary consumers which eat poisoned plants or prey those who have been exposed to pesticides.
Insecticides can travel great distances through the environment and they can also flow with rain water into streams so fish can be directly or indirectly impacted by pesticides. The phenomenon of nutrient enrichment of aquatic bodies is known as eutrophication, which deteriorate the water quality leading to death of fish. Some long-term exposures cause abnormalities or mutations in developing fish larvae, while acute exposure can cause immediate fish die-offs. The liver, kidney, brain and gills of exposed fish are extremely vulnerable to chemical exposure.
Once you finish
growing to adulthood, neurons stop dividing. Hair follicle cells constantly
divide throughout your lifetime since they are constantly producing cells that
become part of the hair itself as they die. So in an adult, the rate of cell
division for neurons is zero (although there is some counter-evidence but it is
certainly very low) while the hair follicle rate is much higher on the order of
once every few days or faster.
Answer:
C
Explanation:
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
The answer is C. Producers make food which os then consumed then decomposers eat the remains.
Glacial evidence discovered in South America demonstrates how climate change evidence has bolstered the notion of continental drift. Folded mountains in Africa and South America. Thus, the correct option is D.
Climate change is happening all across the planet on a daily basis. This is primarily due to human activities that have had an impact on the atmosphere and the earth.
<h3>
What is continental drift?</h3>
Continental drift is basically the hypothesis that the continents once constituted a single landmass, disintegrated, and drifted to their current places.
The discovery of glacial evidence in South America has led to a greater acceptance of the continental drift idea.
Finally, we can conclude that glacial evidence discovered in South America demonstrates how climatic change evidence supports the hypothesis of continental drift.
