The most common elements present in organic compounds are carbon, hydrogen, oxygen, and nitrogen.
The three main ideas of cell theory are that:
<span>
1. All living things are made up of one or more cells. </span>
<span>2. Cells are the basic units of life in which activities of life occur. </span>
<span>3. Living cells come only from other existing and living cells. </span>
One of the use of Agriculture is that It bears no effect on the environment
unlike any other industry , If it done right, Agriculture will leave no side effects to the environment. It basically just let the nature do it's thing and we harvest the result.
Answer:
Option D- frequency of the heterozygous qenotype
Explanation:
In the Hardy-Weinberg equilibrium , 2pq stands for the genotype frequency of heterozygotes (Aa) in a population at the state of equilibrium. dominant homozygotes (AA) is represented by the p-square and q- square represents the recessive homozygotes (aa) frequency. p represents the allele frequency of A Allele and q stands for the allele frequency of the allele a. Summation of the terms gives an equal to 1(100%). The sum of all of these terms is always equal to due to the fact that the 3 frequencies in the equation are the available or possible allele combinations.
Hardy-Weinberg is relevant for it helps us in comparison of a population's actual genetic structure as time goes on along with the genetic structure we are to get if really population was in Hardy-Weinberg equilibrium state that is population was not evolving.
<span>The ecosystem is the lowest level of the biosphere hierarchy to include weather patterns and soil conditions.
in the whole biosphere hierarchy, ecosystem actually placed as the second highest (1 place below biosphere)
But there are only 2 hierarchy that include weather and soils, and those hierarchies are biosphere and ecosystem. So technically the ecosystem will be the lowest in this matter</span>
