Answer:
Argon
Explanation:
Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.

<h2>(A) is the correct option </h2>
Explanation:
- An organism is part of a community is correct,where species interaction occurs between different organisms
- A community is part of population is the incorrect statement because a community includes group of population of two or more different species
- An ecosystem is made up of only organisms is the incorrect statement because ecosystem is the community of both living and non living components of the environment and how they interact with each other
- A biome is the biotic part of an ecosystem is incorrect because biome includes the community of both plants and animals occupying a large habitat
Answer:
proteins; purify; expression
Explanation:
One of the products of recombinant DNA technology is antibiotics. To have penicillin, we used to have to breed fungus that produces the drugs. With recombinant DNA technology, you can extract the DNA that needed to produce penicillin, then put it into a bacteria using an expression vector. This technology will allow us to produce a specific protein (whether its enzyme, hormone, or anything) easier.
The answer is letter A. In most organisms cellular respiration usually involves oxygen to produce the most energy. Except in the process of fermentation, where the cells are deprived with oxygen causing it to form bacteria and other forms of organisms within the fermented sample.
A. They live in the polar regions of the Northern and Southern Hemispheres.
