Explanation:
Mutations increase variation within a population.
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Further Explanation:
During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

The correct answer is <span>d. 62%.
Since Ellie's decision will be based 100 % on Janice's decision, the probability that both will attend the class is 62 % because that is the chance that Janice will attend the class. Since Ellie just depends on Janice, the correct answer is </span><span>d. 62%. I hope this answer helped you. </span>
It helps with the optic nerve, if you give me options i can help answer. Sorry if I didnt help :)
C. often because t<span>here are three major types of </span>plate<span> boundaries. If </span>two<span> tectonic </span>plates<span> collide, they form a convergent </span>plate<span> boundary. Usually, one of the converging </span>plates<span> will move beneath the other, which is known as subduction.

<span>Down syndrome
is a chromosomal condition that is associated with intellectual
disability, a characteristic facial appearance, and weak muscle tone
(hypotonia) in infancy. All affected individuals experience cognitive
delays, but the intellectual disability is usually mild to moderate.</span>
