Test Your Hypothesis by Doing an Experiment:<span> Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test. You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same.</span>
You should also repeat your experiments several times to make sure that the first results weren't just an accident.
Answer:
The correct answer will be option-sequencing DNA from a group of species from the same ecosystem
Explanation:
Metagenomics is the molecular genetic tool used by the molecular biologists in studying the DNA samples of the uncultured organisms.
The metagenomics involves the collected samples of the environment directly sharing the same ecology. This involves the collection of samples of multiple organisms at the same time as the case of microorganism and then differentiating the DNA samples.
The technology provides an advantage over genomics and used by the environmentalist and microbiologist mostly.
Thus, the selected option is the correct answer.
The skin regulates body temperature by perspiration or by using the arrector mucle that holds the hairs on skin. During a hot day, the skin perspires....it gives out water along with sebum and other salts and substances which cools the body. The arrector muscles loosen the hair due to which the hairs are not erect. During a cold day, the arrector muscles forcibly erect the small hairs on the skin which trap the heat of our body and provide insulation. In this way, it regulates temperature.
