What is the structure not present in early elephants?

Biology

Alexus [3.1K]3 years ago

<span>It is a common misconception that elephants existed the same time as the dinosaurs did when in fact they have evolved 3 or 5 million years after these creatures.

The tusks of the elephant would probably be the structure not present in early elephants. It is only through evolution that these tusks grew. Some scientists have hypothesized that these tusks develop from the elephants' incisors.

Answer:

1. kidneys 2. Lungs 5. Pancreas

Explanation:

The body's balance between acidity and alkalinity in the human body is regarded as the acid-base balance which is measured on the basis of the pH and the concentration of carbon dioxide and bicarbonate in the blood. The organs that controls acid-base balance are lungs, kidneys and pancreas. Theses organs control blood pH by releasing carbon dioxide from the lungs because it is a waste product slightly acidic in nature and excreting excess of acids and bases from the body.

Where is long-wavelength radiation created?
Ivahew [28]

On the earth surface

Explanation:

The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.

  • The sun releases radiation in form of short-wave.
  • They are usually more energetic and with short wavelength and a high frequency.
  • When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
  • Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
  • When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
  • Earth is cooler than the sun
  • When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
  • When the short waves are absorbed, they lose some of their their energy to the earth surface.
  • The remainder is radiated back as less energetic long waves.
  • The hotter a body is, the more energetic the radiation it releases.

frutty [35]

The question is incomplete.

The complete question is:

A client comes to the physician's office for a follow-up visit 4 weeks after suffering a myocardial infarction (MI). The nurse takes this opportunity to evaluate the client's knowledge of the ordered cardiac rehabilitation program. Which evaluation statement suggests that the client needs more instruction?

A. "Client performs relaxation exercises three times per day to reduce stress."

B. "Client walks 4 miles in 1 hour every day."

C. "Client's 24-hour dietary recall reveals low intake of fat and cholesterol."

D. "Client verbalizes an understanding of the need to seek emergency help if his heart rate increases markedly while at rest."

Answer:

Option B. "Client walks 4 miles in 1 hour every day."

Explanation:

A myocardial infarction (MI) or heart attack occurs when there is no sufficient blood supply to the heart due to less blood flow which causes damage to the heart muscle.

After 4 weeks of MI, a client will be provoded more instruction on the basis that " Client walks 4 miles in 1 hour". The physician should suggest him to walk for 2 miles in less than 1 hour as walking 4 miles in 1 hour can cause another MI due to increase in the oxygen demand of heart.

Therefore, client should be provided precautions regarding appropriate exercise. Client will be notified about the cardiac rehabilitation program that include relaxation exercises, to follow low-cholesterol diet, and seeking emergency help if heart rate increases suddenly.

Thus, the correct option is B.
