Define the terms "Aldonic Acid", "uronic Acid", and "Aldaric Acid"
sesenic [268]

Explanation:

Aldonic Acid:

Aldonic acids are suger acids.

General formula of aldonic acid = HOOC-(CHOH)_n-CH_2OH

Aldonic acids are obtained by the oxidation of aldehydic group of suger.

So, aldonic acids have hydroxyl group at one terminal and carboxylic group at another terminal.

Gluconic acid is an example of aldonic acid.

Uronic Acid:

It is also a type of suger acid having carbonyl functional group at one terminal and carboxylic group at other terminal.

It is obtained by oxidation of hydroxyl group of the sugar.

Aldaric Acid:

Aldaric acid is also a type of sugar acid having carboxylic acid functional group at both the ends.

Both the hydroxyl group and aldehydic group are oxidized to form class of compound, called aldaric acid.

Answer is below with the steps in order

Explanation:

4) Blood picks up carbon dioxide from the body

7) Heart pumps carbon dioxide rich blood to the lungs

8) Inhale

9) Nose traps germs in air

10) Air moves down the trachea

3) Air moves through bronchi into the bronchioles

6) Alveoli receive oxygen pass to blood

9) Oxygen passes into the blood

11) Alveoli receives carbon dioxide from the blood

12) Oxygen-rcih blood flows to the heart

3) Carbon Dioxide moves from bonchioles to bronchi

13)Carbon dioxide flows up

1) Heart pumps oxygen-rich blood to the body

The last <em>four of five</em> steps could be switched up a little bit since it all happens synchronously, but this is the most accurate interpretation.
