Answers
Answer:
1)Oxidation and Reduction with respect to Oxygen Transfer. Oxidation is the gain of oxygen. Reduction is the loss of oxygen.
2)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.
3)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. Each stoma is made of two bean-shaped cells called the guard cells.
4)The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.
5)Summary. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. ... In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.Jan
6)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.
7)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.
8)Remedies to treat muscle cramps?
Passive stretching and massage.
Active contraction of antagonist muscle group (e.g. contracting hamstring to stretch quadriceps)
Icing affected muscle group
