A small population of mice is released into a meadow. Many but not all of the mice survive and reproduce, and this pattern conti

nues for many generations of mice. According to Darwin's ideas about evolution, which of these conditions is necessary for natural selection to occur on the mouse population? A. Any mutations in the population do not affect the fitness of a mouse. B. The meadow provides unlimited resources to support the mice. C. Traits that affect the survival of the mice vary among individual mice. D. The environment of the meadow remains about the same from year to year.

<h2>C) option is correct </h2>

Explanation:

Natural selection as proposed by Darwin is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit

Causes of natural selection include: Genetic drift, mutation(changes allelic frequency) and sexual selection

In the given example, condition necessary for natural selection to occur on the mouse population is traits that affect the survival of the mice vary among individual mice, in this condition superior genotype will get the opportunity to reproduce and inferior genotype does not get opportunity to reproduce thus their genotype in population does not increase rapidly and hence they become eliminated leading to genetic drift

What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell
spin [16.1K]

Answer:

This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.

Explanation:

Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.

Describe the connection between fossil fuel burning, the melting of polar ice, and the rising of global sea levels.
padilas [110]
Burning fossil fuels will produce carbon dioxide which is a global gas causing global warming . Global warming causes the sunlight to be trapped in the atmosphere of the earth which will cause the temperature of the earth to increase. so the polar ice will melt and the sea level will increase

In a particular human family, John and his mother both have brachydactyly (a rare autosomal dominant allele causing short finger
Luba_88 [7]

Answer:

Brachydactyly and Huntington are phenotypic diseases that develop when a person has one or two dominant alleles for these traits.

John's father has the Huntington disease, but not brachydactyly so his genotype is Hh/bb.

John's mother is a healthy women with brachydactyly, so her's genotype is probably hh/BB or hh/Bb.
