What are the definitions for gene pool and allele frequency?
A. the alleles for a species, the number of times a gene appears
B.the number of alleles: genes that appear in a population
C.all the alleles that appear in a population: the number of times the alleles appear
D.all the genes that are present in a population; the number of times an allele occurs in a gene pool​

Answers

Answer 1

Answer:

Allele frequency- the percentage with which a specific allele is found in a population. Gene Pool- the sum total of all alleles present in all populations of a particular species. ... evolution involved a change in allele frequency in a population's gene pool over a number of generations.

Explanation:

I hope this helps :)

Answer 2

A gene pool is defined as the number of alleles. and the allele frequency is defined as the  genes that appear in a population. Therefore, option B is correct.

What is gene pool ?

A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.

A gene pool is the collection of all the genes, including all the various alleles, in any population that mates with other individuals from the same or different species. The percentage of an allele within a population is known as the allele frequency.

A population's gene pool will include a high number of genes with a wide range of frequencies. Gene frequencies are proportions of various alleles within a population, and in any given generation, these frequencies will rely on those of the previous generation.

Thus, option B is correct.

Group of answer choices weathering and erosion into sediments, then deposition and lithification rocks get buried deep in the earth where they melt and then cool rocks are under heat and pressure so they can change rock is split into larger pieces and then dissolves in water where it hardens into rock

Answers

Answer and Explanation:

Igneous rocks form most of the earth´s crust. They are the result of the solidification of rocky, molten material, the magma. Rocks are melt in the interior of the earth´s crust or in the mantle, and then, as they are less dense than the other rocks, tend to ascend toward the surface. As they ascend, they get cold and solidify.

There are two kinds of igneous rocks, according to the moment of solidification. Extrusive igneous rocks are the ones formed when the molted material gets to get to the earth´s surface and crystalize there. Intrusive rocks get formed when the magma loses its motility before reaching the surface, ending by crystalizing in the deepness.

4 genetically different haploid cells.

What is Meiosis?

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).

The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.

Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent.

Therefore, 4 genetically different haploid cells.

Answer:

habitat destruction

Explanation:

A forest ecosystem offers a variety of ecosystem services and functions. Prominent among the services offered include habitats to a variety of fauna, watershed protection, carbon sequestration, etc.

When the trees in a forest are removed by clear-cutting, some of the services and functions specific to the tree layers cease. The various habitats provided are destroyed and the organisms that live in these habitats disappear.

Hence, if a forest ecosystem is removed through clear-cutting, many species of organisms that lived in that ecosystem disappear. Their loss is due to habitat destruction.

Answers

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code

Explanation:

As a sequence of nucleotides it is the information for a specific protein carried on the DNA molecule. The correct option is A.

What is nucleotide sequence?

The most fundamental understanding of a gene or genome is its nucleotide sequence.

Without having this information, no understanding of how genes function or how evolution works would be complete. It is the blueprint that carries the instructions for developing an organism.

The four nucleotides that make up DNA are adenine (A), thymine (T), guanine (G), and cytosine (C) (C).

The two DNA strands are connected by base pairs, which are formed when the nucleotides (A with T and G with C) bind to one another.

It is the data for a particular protein contained on the DNA molecule as a sequence of nucleotides.

Thus, the correct option is A.

Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.

What is Urbanization?

The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.

On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
