Answers
1)
Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).
2)
Respiratory rate: The number of breaths per minute or, more formally, the number of movements indicative of inspiration and expiration per unit time. In practice, the respiratory rate is usually determined by counting the number of times the chest rises or falls per minute.
3)
The diaphragm separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.
4)
All living organisms respire. Cells need and use the energy that is formed through this process to assist with life processes in order for organisms to survive and reproduce. Oxygen and carbon dioxide are the main gases involved in aerobic respiration. ... These conditions are called gas exchange surfaces.
5)
Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria.
or
The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion. The folds in the inner membrane are called cristae.
6)
the end products of aerobic respiration are 38 atp of energy, carbon dioxide and water while of anaerobic respiration is ethanol and 2atp of energy. Aerobic respiration occurs when your cells produce energy in the presence of oxygen.
7)
Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
8)
Cellular respiration is the process of breaking sugar into a form that the cell can use as energy. This happens in all forms of life. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.
9)
Spiracles are external openings found in some animal species, such as insects, spiders and some species of fish and whales. The function of spiracles is linked to respiration, helping oxygen to reach internal respiratory organs, such as lungs in whales and tracheae in insects.
10)
Anaerobic respiration in muscles. Glucose is not completely broken down, so much less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
11)
When exhaled air is blown through Lime Water which is also known as calcium hydroxide, the carbon dioxide present in the exhaled air reacts with the Lime water and turns it into a milky solution, since the the CO2 reacts with Ca(OH)2 and forms CaCO3 or Calcium Carbonate, which is insoluble and white in colour.
12)
Hair in the nose is one of the body's first lines of defense against harmful environmental pathogens such as germs, fungus, and spores. Another purpose for nose hair is to provide additional humidity to the inhaled air. As the air passes through the nasal passages, the mucus and hair provide heat and moisture.

1----Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). ... The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
2----Yeast respires anaerobically and during this process, yeast converts glucose into alcohol. Therefore it is used to make alcohol bread, etc. Anaerobic respiration produces much less energy because the only partial breakdown of glucose occurs in anaerobic respiration in the absence of oxygen.
3---Anaerobic respiration in muscles. Glucose is not completely broken down, so much less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
1. It takes place only in the cells containing chlorophyll.
2. It takes place only in the presence of light.
3. Photosynthesis utilizes carbon dioxide and water.
4. The end products of photosynthesis are carbohydrates and oxygen.
5. During photosynthesis, the light energy is converted into chemical energy in the form of carbohydrate.
7. Hydrogen released during the photolysis of water is accepted by NADP which is reduced to NADPH2.
8. ATP synthesized is used in the dark reaction of photosynthesis.
9. The entire process of photosynthesis occurs in chloroplast.
10. Rate of photosynthesis is usually 20 times more than that of respiration.
Aerobic
Respiration
1 Oxygen is present when this form of respiration takes place.
2 Gases are exchanged in this form of respiration.
3 It can be found in the cytoplasm and the mitochondria.
4 Glucose breaks down into carbon-di-oxide and water.
5 All organisms such as mammals have this type of respiration.
1 Oxygen is absent when this form of respiration takes place.
2 Gases are not exchanged in this form of respiration.
3 It can be found only in the cytoplasm.
4 Glucose breaks down into ethyl alcohol, carbon dioxide, and energy
16) Earthworms have moist skin because it is necessary for oxygen to be absorbed and carbon dioxide to be given off. The worm's skin is protected by a thin cuticle and kept moist by a slimy mucus. This lets it absorb the oxygen it needs and expel carbon dioxide.
When the athlete runs in the race, his body needs more oxygen. His rate of breathing increases so that more oxygen can be supplied to the body. This is the reason, an athlete needs to breathe faster and deeper than usual; after finishing the race.
Because the nostrils are smaller than the mouth, air exhaled through the nose creates a back flow of air (and oxygen) into the lungs. And because we exhale more slowly through the nose than we do though the mouth, the lungs have more time to extract oxygen from the air we've already taken in.
Stretch and massage. Stretch the cramped muscle and gently rub it to help it relax. For a calf cramp, put your weight on your cramped leg and bend your knee slightly. ...
Apply heat or cold. Use a warm towel or heating pad on tense or tight muscles.
Lungs. Smoking can cause a variety of lung problems. ... Primarily, smoking damages the airways and air sacs (known as alveoli) in the lungs. Often, lung disease caused by smoking can take years to become noticeable, this means it is often not diagnosed until it is quite advanced.
