pishuonlain [190]3 years ago
3 0

Answer:

Catabolic pathways

Explanation:

Catabolic pathways release energy by breaking down complex molecules to simpler ones.

For example, in cellular respiration, glucose is being breaking down into CO2, H2O, and ATP.

When thinking of the functions of the organelles.which cell tissue in the human body would have the most mitochondria and why
Anni [7]

Answer:

Muscle cells, especially heart muscle cells and fat cells have the most mitochondria in the human body.

Explanation:

Mitochondria, the powerhouse of the cell is an organelle where cellular respiration occurs. They supply energy to the cells for their functioning. The number of mitochondria in a cell vary depending on the energy requirement of that cell.

Muscle cells are very active in our body and need energy for the movement. Heart muscle cells require a lot of energy to contract and pump blood through the circulatory system all the time. So they have a lot of mitochondria to produce a vast amount of energy they need.

What does diffusion do in the respiratory system and circulatory system
GenaCL600 [577]

Answer:

Diffusion in the Lungs trades out Carbon Dioxide (CO2) for Oxygen (O2) In the Circulatory system it trades Oxygen (O2) for Carbon Dioxide (CO2)

Explanation:

As you breathe the Lungs take in air, as they do that the air travels to the bronchi, from there it goes through a process where the veins which have carried de-oxygenated blood to be diffused and reloaded with Oxygen and trade off their CO2. Then the blood flows through arteries and delivers the needed O2 to cells throughout the body and the cycle repeats.

31. The data in the accompanying graph show evidence of disease in the human body. D 38 - - E Body Temperature (°C) 377 А IDOT B
shepuryov [24]

Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. <em>A </em><em>disruption i</em><em>n </em><em>dynamic equilibrium </em><em>is indicated by the </em><em>temperature </em><em>change between point C and D.</em> Option C is correct.

<h3>What is homeostasis?</h3>

Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.

Homeostasis is critical to keep the correct internal functioning of the body.

Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a<u><em> </em></u><u><em>restricted range</em></u><u><em> </em></u>around a reference point, even though external conditions may be changing.

When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.

<h3>Graph interpretation</h3>

In the exposed graph we can see,

  • The restricted range of homeostasis at a constant temperature around 37ºC.

  • Six reference points (A-F) withing 12 hours.

  • Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.  

The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.

A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.

The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.
