What was not considered in early taxonomic classifications

1 answer:

4 0

The internal structue and phylogenetic relationships were not considered in early taxonomic classifications. Early classifications were mostly based on morphological characters like height, shape, color etc. The organisms have evolutionary relationships which were also not considered in earlier classifications.

If we compare the genetic codes of the four organisms seen here, which statement is MOST accurate?

bezimeni [28]

<h3>Answer;</h3>

All four organisms have exactly the same components in their DNA, but it varies in number and sequence

<h3>Explanation;</h3>

DNA, known as deoxyribonucleic acid is a type of nucleic acid which is important to all living organisms as it helps store genetic information.
All living organisms store their genetic information using DNA molecules or RNA molecules. Most organisms contains DNA that have similar components, however their DNA will differ in number and also the sequences.
The similarity between the molecules of DNA indicates a common ancestry among organisms.

Tom has developed chronic kidney disease. he has lost weight and has a poor intake. the most likely cause is:

almond37 [142]

Chronic kidney disease is when your kidney is not functioning properly. Kidneys contain filters called nephrons. It is the their job to filter the blood of waste products and extra fluid. As a result, your body flushes the waste out as urine. The most common causes of chronic kidney disease are diabetes and high blood pressure. If your blood vessels contain a high concentration of sugar and cholesterol, the nephrons would take the exhaustive work. In the long run, if you keep eating unhealthy food, the kidney could no longer catch up. Thus, resulting to chronic kidney disease.

Olympic athletes train in Colorado Springs, Colorado because this location is at high altitude and near the 14,000 foot Pikes Pe

Stels [109]

Answer:

A: Oxygen levels are low and, therefore, more red blood cells are produced, giving the athletes an advantage when competing at lower altitudes.

Explanation:

At high altitudes, the partial pressure of oxygen is lower compared to lower altitudes. The body system try to adjust to lower oxygen level by undergoing several physiological changes. Depending on the duration spent in high altitude, the body can either try to adjust in the short term or acclimatize for a longer term.

One of the processes the body undergoes during acclimatization is an increase in red blood cell production. The kidney secretes erythropotein in response to inadequate oxygen in body tissues, and this makes the liver to increase erythrocyte production.

The increase in red blood cell production correspondingly increases the oxygen-carrying capacity of the blood as a result of increased hemoglobin. This condition persists for a few weeks even after the body returns to lower altitude where oxygen is adequate. Increased oxygen capacity means the rate of energy production (through respiration) within the body will also increase

Hence, those who acclimatize to high altitude usually experience increased capillary density, tissue perfusion and improved athletic performance at lower altitudes.

The correct option is A.
