The Hardy-Weinberg Principle predicts that allele and genotype frequencies should not change over time in a stable population. Which of the following assumptions must be met for this to occur? Select all that apply. a. There is selection pressureb. There is migration into or out of the populationc. Random mate choiced. A large populatione. No new mutations

c).Random mate choice

d. )A large population e.) No new mutations

Explanation:The Hardy-Weinberg Principle predicts that in the large randomly mated population in the absence of migration,selection and mutation the gene frequencies remains the same. Hence, for the allele and genotype frequencies to remain constant there must be; a)random mated population b)large population c) No new mutation.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
