Answer:
A) The greater the variance within the population, the larger the sample should be.
Explanation:
The variance of a sample mean is inversely proportional to the sample size, that is, the larger the sample size the smaller the variability of the sample. When sample size increases, the range decreases and hence the variance decreases resulting in a more accurate research result with minimal experimental error.
Hence the researcher should employ a large sample size to reduce the variation in the population.
Answer:
Igneous Rocks: form by crystallizing melted material (magma). They can form either on the surface (extrusive igneous rocks), or deep in the crust (intrusive or plutonic igneous rocks). Volcanoes are places where magma erupts as lava or ash.
<span>There are two ways. One is their claws that can rip flesh apart but they don't really tend to use it all that much since they're not really that endangered by predators. Another way is their skin and fur which is collored in such a way that they can camouflage themselves among trees or plants and often look like tree bark.Hope this helps. Let me know if you need additional help!</span>
Answer:
Synthesize nutrients using carbon dioxide and water.
Explanation:
- The autotrophs are organisms that produce their own food through form the substance available in their surroundings using light or the chemical energy.
- The heterotrophs who can synthesize their own food and rely on the other organisms for nutrition. They are responsible for the flow of the carbon and the water nutrients and in a close synthesis of the matter flow in the energy cycle.
