Answer 1

Answer:

1. Oxidation is the loss of electrons. ... In terms of oxygen transfer, oxidation may be defined as the chemical process in which a substance gains oxygen or loses electrons and hydrogen.
2. The muscles that power your lungs are also part of the respiratory system.
3. Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
4. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.
5. the process of anaerobic respiration in yeast is: the glucose is broken down to form energy which is taken by the organism. Ethyl Alcohol or Alcohol, Carbon Dioxide and Water are also formed. Yeast are used to produce wine and beer as they produce Ethyl Alcohol which is used in wines and beers
6. Passive stretching and massage.
7. Active contraction of antagonist muscle group (e.g. contracting hamstring to stretch quadriceps)
8. Icing affected muscle group
9. Overwatering in potted plants is of the most concern, as they are in a captive habitat. Nutrients are washed away and mold or fungal issues may develop with overwatering. Under watering creates an inhospitable environment where plants can't intake nutrients and wither or die.
10. Stomatal apparatus is a pair of guard cells with or without surrounding subsidiary cells which function as a value to open or close a stomatal pore for gaseous exchange and transpiration.

Answer 2

1 - Oxidation is the loss of electrons or increase in oxidation state of an atom, ion or molecule in a Chemical reaction.

4 - Respiration is simply the act of breathing. The lungs are the major organs for respiration and gas exchange.

5 - Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
