Claim evidence reasoning mutation

Biology
1 answer:
olchik [2.2K]3 years ago
3 0

Explanation:

-increases genetic variation

-increases the fitness of a species

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. 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.

Like 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 are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage

.

e.g. sickle cell anemia, a disease caused by a mutation, confers protection against the disease malaria.

number 2: Arteries have a thick wall which helps a powerful pressure from the heart.

number 3: Without the Circulatory System the body wouldn't be unable to maintain a internal environment.

number 4: The Circulatory and Respiratory system both have gas to help a or animal live in there internal environment.

number 5: Blood vessels brings oxygen to the tissues and absorbs carbon dioxide and other waste products to clear the lungs. And with out oxygen the tissues won't absorb carbon dioxide to clear out the lungs.

A man of healthy weight may have, on the average, ____ percent of his body weight as fat.
Nat2105 [25]
The correct answer is 20% on average. The ideal percentage rate of a healthy man with normal weight is 18 to 22%. However, a range of 7-13% is considered normal for male professional athletes, because their muscular mass is much greater. The physiological minimum rate which is acceptable for males is 4-6%.

Carbon-12 and Carbon-14 are isotopes; it means that
jok3333 [9.3K]
A :-) Isotopes are forms of the same element with equal numbers of protons but different numbers of neutrons. For example, both carbon-12 and carbon-14 have 6 protons. But carbon-12 has 6 neutrons while carbon-14 has 8 neutrons. By definition, carbon-12, carbon-13 and carbon-14 are all isotopes of the carbon.
