Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation c
krek1111 [17]

Answer:

Mutations can occur from the following ways:

1. Errors that occur in DNA replication during cell division

2. Exposure to high-energy electromagnetic radiation

3. Exposure to chemicals mutagens

Effects of mutation include:

1. Genetic disorders

2. Cancers

Explanation:

A mutation is a change or alteration that occurs in the DNA sequence of a cell of an organism. These mutations can be passed on to offsprings of that organism. Mutations can occur from the following ways:

1. Errors that occur in DNA replication during cell division: during the process of cell division, the DNA in cell are copied many times. Some errors result when copying DNA, most of which are corrected during proofreading. However, some changes in the DNA sequence may not be corrected, thus resulting in a mutation.

2. Exposure to high-energy electromagnetic radiation: some types of electromagnetic radiation are ionizing, such as UV rays and X-rays. Prolonged exposure to these ionizing radiation may result in permanent damage to parts of the DNA, thereby resulting in a mutation.

3. Exposure to chemicals mutagens: mutagens are substances which are able to cause mutations. Some common chemical mutagens are alkylating agents such as ethylmethane sulfonate and N-methyl-N-nitrosourea.

Effects of mutation include:

1. Genetic disorders: in genetic disorders, certain normal functioning of the body processes are impaired. For example, hemophilia whereby blood lacks the ability to clot normally resulting in excessive bleeding.

2. Cancers: cancers occur when the cell of the body differentiate and grow abnormally. Various types of cancers include breast cancer, prostrate cancer, blood cancer etc.

Differentiate among somatic cells, gametes, and zygotes with regard to the number and origin of their chromosomes.
andrew-mc [135]

Answer:

Somatic cells are the ones obtained by mitosis. They constitute the body tissues and have a variety of different functions. They are <em>diploid</em>, which means they have two copies of each chromosome (2n), one obtained from the father and one from the mother.

Gametes are obtained by meiosis. A diploid cell divides to form four <em>haploid </em>gametes, they have a single copy of each chromosome (n), obtained from the parent cell.

Zygotes are obtained by the fusion of two gametes, one from the father and one from the mother, they are <em>diploid </em>again having two copies of each chromosome.

A 7-month-old girl is to be catheterized so a sterile urine specimen may be obtained. one of the infant's parents expresses fear
NemiM [27]

The 7-month-old infant is accustomed to having the perineal area exposed and cared for and is not in a developmental stage in which fears related to sexuality are present. A "clean catch" at this age is often contaminated; therefore catheterization has been prescribed. The parents do have the right to refuse, but this concern is not realistic an infant of this age. The parent's concern is not appropriate for the developmental age of the infant.
