Answer 1

1. Roughages are the fibres of either carbohydrates or proteins. They keep a person healthy by keeping the intestine working and moving other food quickly through the alimentary canal.
2. answer is in the picture no.1
3. Potted plant,wide mouthed bottle,KOH,etc.
4. Epiglottis is a flap like structure which helps in letting the food to move through food pipe and air to move through wind pipe. Diaphragm is a muscular dome like structure that helps in inhalation and exhalation.
5. answer is in the attachment.
6. If respiratory track is not moist, air can't move easily. This moist nature also regulates surrounding temperature .
7. Peristalsis is the contraction and relaxation of oesophageal muscles which bring in a wave motion that propels the food bolus into stomach by action.

Answer 2

Answer:

1)Regulates Digestion

One of the main benefits of eating roughage is that it helps to regulate your digestion. Insoluble fiber provides bulk in your intestines and helps to keep food moving through your digestive tract

3)Image result for list of the materials required to perform the experiment that carbon dioxide is essential for photo synthesis

To show that carbon dioxide is necessary for photosynthesis. bell jars, vaseline, watch glass, potassium hydroxide, alcohol, spirit lamp and beaker. leaves are destarched

2)attached to the document

4)It prevents food from entering the wing pipe. Diaphragm adjusts it's shape (expand and contract) for inhalation and exhalation. Diaphragm is a muscular membrane present below the lungs. ... When we swallow water or food, the trachea gets covered by epiglottis, thus preventing the entry of food or water into lungs

5)In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yields glucose and oxygen in photosynthesis. ... Photosynthesis is an anabolic process, whereas cell respiration is a catabolic process. Let us know about more differences

6). 1) If the respiratory tract is not moist the dirt particles in the inhaled air will not be removed from air in the nasal cavities and reaches lungs and create problems to lungs. 2) The temperature of the inhaled air is brought close to that of the body for the smooth passage in the respiratory tract

7)the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements that push the contents of the canal forward.

8)This is because a plant produces oxygen during daytime with photosynthesis but as well as respire throught the day and night and in respiration it releases carbon dioxide and consumes oxygen, therefore it is a producer as well a consumer but it produces more oxygen than it itself consumes, so plants do not consume all ..

9)Prevention tips include: Increasing your fiber intake: Fiber-rich foods, such as fruits, vegetables and whole grains, all help improve gut function. If you have bowel sensitivity, you'll want to avoid high-fructose fruits, such as apples, pears and watermelon, which can cause gas.

10)Mitochondria are small organelles inside cells that are associated with discharging vitality from nourishment.it is known as cell breath. The mitochondria are frequently alluded from the powerhouses of the cell. it is known as powerhouse of cell. ... Mitochondria is the force place of the cell.         diagram attached to the document

11)1-The respiration which takes place through buccopharyngeal cavity,

  2-insects

  3-Respiration. Earthworms have no special respiratory organs. Gases are exchanged through the moist skin and capillaries, where the oxygen is picked up by the haemoglobin dissolved in the blood plasma and carbon dioxide is released. Water, as well as salts, can also be moved through the skin by active transport.

  4-Mandible

12)The mechanical breakdown takes place in which of large pieces of food is broken down into smaller one. While the chemical digestion takes places by the action of digestive enzymes. The gastric enzymes that is released from the stomach start digestion of protein. It start in the mouth when the food is chewed and ends in the small intestine.

13)the food habits which can be followed after reading the nutrition chapter is

1) having simple well balanced meals

2) eating them in Leisurely Manner

3) thoroughly masticating the food

4) avoiding violent exercise soon after eating food

5) drinking plenty of water and having regular bowel movements

14)In plants, the so-called "light" reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.

15)Put some germinating seeds in a conical flask. The conical flask is fitted to a delivery tube bent twice at right angles by means of cork. Suspend a small test tube containing 20% potassium hydroxide. ... The germinating seeds respires aerobically by utilizing the oxygen in the flask

16)The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata. ... This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata.

17) 1-Glycolysis

Glycolysis is the metabolic process that serves as the foundation for both aerobic and anaerobic cellular respiration.

2-Lactic acid is produced in your muscles and builds up during intense exercise. It can lead to painful, sore muscles.
