Explanation:
Answer:
Test a hypothesis
Explanation:
An experiment is done to test a hypothesis. An experiment can either prove or disprove a hypothesis. The experiment should be designed in a way that it can be repeated for validity to ensure that the results that come out of it holds true each time.
A hypothesis is made before the experiment is done. Developing data is done through interpretation of the results of an experiment. A conclusion is formed through analysis of the data obtained from an experiment.
Answer:
pollutants such as sulfur can lead to excess levels of acid in lakes and streams, and damage trees and forest soils; atmospheric nitrogen can reduce the biodiversity of plant communities and harm fish and other aquatic life; ozone damages tree leaves and negatively affects scenic vistas in protected
Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).
When water pollution causes an algal bloom in a lake or marine environment, the proliferation of newly introduced nutrients stimulates plant and algae growth, which in turn reduces oxygen levels in the water. ... Marine ecosystems are also threatened by marine debris, which can strangle, suffocate, and starve animals.
Noise pollution has a negative impact on wildlife species by reducing habitat quality, increasing stress levels, and masking other sounds. Chronic noise exposure is especially disruptive for species that rely on sound for communication or hunting (
Answer:
A. Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host.
Explanation:
Genetic engineering, also known as genetic modification, is a technique that involves the manipulation of an organism's genome using biotechnology procedures. The purpose of genetic engineering is to create an organism with desirable traits.
Genetic engineering involves series of steps, however, the very first step is that of DNA EXTRACTION. The fragments of DNA that have desired genes are isolated from the involved organism. The extracted DNA called the recombinant DNA, which is inserted into the host genome.
