Answer:
Greenhouse gases
Explanation:
Teddy is working for a nonprofit organization that urges people to stop using products with CFCs. Through this Initiative, Teddy's organization hopes to reduce the concentration of greenhouse gases in the atmosphere.
Greenhouse gases deplete the ozone layer thereby causing global warming as a result often increase in the intensity of Sun rays reaching the earth.
Example of greenhouse gases include chlorofluorocarbon, nitrogen, water vapor etc
Answer:
The answer is D.) Mercury
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.
Molecules are defined as the smallest particles of a chemical compound or an element, and are made up of atoms. Cells are made up of semi permiable membranes that only allow selected materials to move in or out of the cell, therefore due to the big size of molecules compared to atoms the membrane doesn't allow their passage in the cell. Therefore the cell doesn't allow most molecules to diffuse passively to the cell. Secondly, molecules that can enter the cell requires specific carriers carriers that will enable entry of small molecules in the cell.
I think it is the secondary ovarian follicle that contains the secondary oocyte.The stages of the ovarian cycle that the follicle will go through includes; a primary follicle contains an oocyte and begins producing estrogen. Then the secondary oocyte contains a secondary oocyte and produces estrogen and some progesterone, then the graafian follicle develops and the secondary oocyte is released a process we call ovulation. the corpus luteum produces progesterone and some estrogen and lastly the corpus luteum degenerates.
