TEMPERATURE: Although enzymes are also affected by the pH and the concentration of the enzyme and substrate in their environment, this specific example shows that enzymes are affected by temperature.

Place the steps of the respiration process in the correct order.
noname [10]

During respiration, 3) Air enters the nostrils. 1) Air passes from the trachea to the bronchi. 4) Air diffuses from the alveoli to the blood cells. 2) Oxygen enters the blood cells. 5) Blood transports oxygen to other cells.

<h3>What is respiration?</h3>

During respiration process occurs gas interchange between the body and the environment.

There are two types of respiration,

1) External respiration involves two different stages, inspiration - inhalation- and expiration -exhalation-.

• During inspiration, the diaphragm and intercostal muscles contractions enhance the size of the thoracic box and reduce internal pressure. As a result, air flows in and fills the lungs.

• During expiration, the diaphragm relaxes, and the volume of the thoracic box diminishes, increasing the internal pressure and making the lungs contract, which results in air expulsion.

2) Internal respiration, during which blood and cells interchange oxygen and carbon dioxide.

Steps:

1) External respiration - Inhalation

Air passes from the environment to the lungs through the nose or mouth.

Oxygenated air moves

• From the nose or mouth to the pharynx.

• From the pharynx to the larynx.

• From the larynx to the trachea.

• From the trachea to the bronchia.

• From bronchia to bronchiole.

• Finally, from the bronchiole to alveoli.

Gas interchange with blood occurs in alveoli.

2) Internal respiration - Systemic circulation

The oxygenated blood moves from the lungs to the heart and the rest of the body.

Gases interchange occurs during this step. Cells take oxygen and release carbon dioxide.

Deoxygenated blood moves from tissues to the heart and from the heart to the lungs, releasing carbon dioxide there.

3) External respiration - Exhalation

Carbon dioxide is released by expiration.

Correct order of steps

3) Air enters the nostrils.

1) Air passes from the trachea to the bronchi.

4) Air diffuses from the alveoli to the blood cells.

2) Oxygen enters the blood cells.

5) Blood transports oxygen to other cells.

Okay, just think Animals

Answer: When using fossils approximate age by comparing it to similar rocks and fossils of known ages, is called relative dating.

Using that method we can determine the age of rock layers. That’s our way of dating them.

Hope this helps! ^^

What do scientists have yet to solve
Brilliant_brown [7]
Global warming. Not reversing it, because that would most likely cause an ice age, but keeping it under control.
