30,000K because it 20,000 more then the other number.
Answer:
The correct answer is C: A spring tide can occur for both position A and position B.
Explanation:
The explanation for the above is very straightforward.
When the moon is between the sun and the earth and when the earth is between the sun and the moon, the gravitational forces of both the sun and the moon tend to exert a pull the earth whose surface is 70% water thus creating higher tides.
These types of tides are called spring tides and occur when the moon is full and when there is a new moon.
Full moon occurs when the earth is inbetween moon and the sun while the new moon occurs when moon is between the sun and the earth.

The total number of people that will be selected is 14.
Explanation:
In the case of stratified random sampling, we first need to split the population into several strata and then select a sample from each. For a given question, the solution type is
Sample size of strata = (Scale of whole sample by population size) multiply strata size
= (20 by 300) multiply 210
After we have resolved, 14 or 14 persons will be chosen.
One value is that here, as we split all the data into strata and then pick samples from them so that they can be used as a protection against unnecessary samples and to have more precise sample measurements. Here, because we needed samples from the population that provided yes and no opinion so that it is easier to use stratified sampling method then if we use simple random sampling then we can use those samples that did not offer an opinion. But since we're not using this form, we can stop it.
Answer:Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.
Energy transfer between trophic levels is inefficient—with a typical efficiency around 10%. This inefficiency limits the length of food chains.
