1. Genetic variation is different combinations of genes/traits/characteristics within a pollination of organisms.
2. Two sources of genetic variation are mutations and sexual reproduction.
3. Sexual reproduction can cause genetic diversity because the offspring inherits combinations of traits from both parents. This means the offspring will inherit and show a variety of traits which increases genetic variations within the individual.
4. Genetic variation is important because it helps the population of a species survive and thrive in their environment. Because there are multiple variations within the species, if there ever is a change in the environment of that species, there is a higher chance that that species will be able to adapt to its new environment because of the variety of variations within the species.
5. Bacterial resistance is when a species of bacteria are not affected by the effects of medications. Thus, they will not die from medications. This happens when a species of bacteria is exposed to the same medication long enough to which there are variations within that species. As the amount of variations grow, there is a higher chance that there will be one variation of bacteria that will not be affected by medicine. That bacteria will survive and pass on its protective traits which creates bacterial resistance.

Symptoms of uric acid.​
irina [24]

Answer:

Elevated uric acid levels lead to a condition known as "Hyperuricemia."

Explanation:

This condition occurs when there is an excessive presence of uric acid in the blood. It can be divided into:

  • Primary hyperuricemia
  • Secondary hyperuricemia

Primary hyperuricemia occurs when the kidneys are not able to eliminate uric acid in an efficient/proper way. This can be due to the consumption of foos that are very high in purines. For example, liver, gravy, alcoholic beverages, and some vegetables such as spinach and asparagus.

Secondary hyperuricemia may occur to several possible reasons. For instance, kidney disease, in which the kidney is not able to eliminate uric acid; chemotherapy, which may lead to the accumulation of uric acids; or medications that increase the level of uric acid in the blood.

Symptoms include:

  • Fever.
  • Extreme and abnormal fatigue.
  • Joint inflammation.
  • Urination problems.
  • Kidney stones.

To prevent this disease and as part of a treatment (along with medications prescribed by a doctor), a patient should opt to consume foods that are low in purine, such as lettuce, tomatoes, cereals, fruits, milk, eggs, amongst others.

What type of fat is necessary for normal bodily function and includes lipids incorporated into nerves and organs?
andrew11 [14]

Answer:

Sphingolipids

Explanation:

They are derived from aliphatic amino alcohol sphingosine and functions in protecting the nerves in the central nervous system. Sphingolipids includes group of lipids called glycolipids and sphingomyelin. Just like phospholipids they have polar heads and two non-polar tails together with proteins, forms a myelin sheath. They  insulate the nerves and causes quick transmission of electrical impulse amongst organs contributing to normal bodily functions.

For glycolysis to produce ATP when no oxygen is present, it is necessary for cells to convert _____ to _____.
ivann1987 [24]
The answer is D. NADH to NAD+

When no oxygen is present, anaerobic respiration occurs.It is the only way to produce ATP in this condition.NAD+ is necessary because it is converted into NADH and at the same time ADP is converted to ATP in the reaction of pyruvate synthesis from glucose.Therefore, NADH must be converted to NAD+ in order to have NAD+ always present in the cell.

Analysis of pedigrees using knowledge of Mendelian principles allows us to; Determine whether the trait has a dominant or recess
Mashutka [201]

Answer:

Determine whether the trait has a dominant or recessive pattern of inheritance

Explanation:

This kind of information can be used to predict inheritance patterns in families. Depending on the genotypes, the dominant and recessive alleles and the different crosses, it can be deduced who are carriers of the disease and who express it. Similarly, by letting us know which chromosome (X or Y) is linked to the disease, we can know if the disease will be transmitted to the next generation depending on the genotypes of the parents.
