Advantages of constant body temperaure

Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life. 

Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm. 

The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size. 

The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.

Why would tissue from the fetal stage of human development be used to look at mitosis?
WITCHER [35]
Mitosis is the process of cell division, where one parent cell divides to produce two genetically identical daughter cells. This process is vital in growth and tissue repair. 
The reason that tissue from the fetal stage is helpful in studying mitosis is because mitosis is continuously and rapidly occurring in this phase of life in humans. The high rate of mitosis is due to the need for the fetus to grow rapidly and develop the necessary parts for it to be born.

What is the approximate Km for the enzyme? Explain.
prohojiy [21]

Answer:

The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax. ... This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity. For practical purposes, Km is the concentration of substrate which permits the enzyme to achieve half Vmax.

Explanation: lmk if this helps

Correctly order the steps in which blood travels through the heart from the time it enters from the systemic circuit until it re
Sav [38]

Answer:

Steps in which blood travels through the heart from the time it enters from the systemic circuit until it returns to the systemic circuit are:

  1. Aorta receives the oxygenated blood from the left ventricle.And gives it to systemic arteries.
  2. Cells recieve the oxygenated blood and give out carbon dioxide laden blood.
  3. The superior and inferior venacava bring deoxygenated blood to the right atrium.
  4. The deoxygenated blood then moves into the right ventricle.
  5. Deoxygenated blood reaches lungs through Pulmonary artery.
  6. Left Atrium recieves blood from lungs through pulmonary veins..
  7. Oxygenated then moves into Left Ventricle.
  8. Aorta recieves the blood from the Left ventricle

Explanation:

There are Two types of circulation in human body; the pulmonary circulation and the systemic circulation.

In Pulmonary circuit the blood is pumped into the lungs from the right ventricle to the lungs through pulmonary arteries. In this circulation the blood gets oxygenated.

In Systemic circuit the oxygenated blood from the lungs is pumped into aorta by the Left ventricle so that it can reach the body tissues,

  • This circuit also brings deoxygenated blood from the body to the Right atrium of the heart.
  • Blood enters the systemic circuit when Aorta receives the oxygenated blood from the left ventricle.
  • The oxygenated  blood then flows into the systemic Arteries and reaches the body tissues.
  • Cell consumes the the required oxygen and nutrients then adds carbon dioxide, hormones and waste material to the blood.
  • The systemic veins collect the deoxygenated blood.
  • The deoxygenetated blood from upper half of the body is carried by superior vena cava and the blood from lower half of the body is carried by inferior vena cava.
  • Both superior and inferior vena cava bring the blood to the right Atrium.
  • From the right atrium, the  blood moves into  right ventricle through tricuspid valve.
  • The Pulmonary artery carries the blood from right ventricle to the lungs.
  • After the carbon dioxide diffuses out and oxygen is added, the blood is taken up by pulmonary vein.
  • The Pulmonary vein brings the oxygenated blood to the left atrium of the  heart.
  • The blood then moves into the left ventricle through the bicuspid valve.
  • The left ventricle then  pumps the blood into the Aorta through aortic valve returning the circulating blood to the systemic circuit
