Question 4.
(a) Give reasons :
(i) Composting is a useful method contributing in crop farming.
(ii) Abnormally a large number of WBCs in the blood are usually an indication of some infection in our body.
(iii) Eating places should be free from flies.
(iv) We cannot hold our breath forcibly for a longer time.
(v) Food tube is partially collapsed when not in use
Answer:
(i) Composting is the process of putting biodegradable wastes in a compost pit to decay, so that by the action of microbes, it gets converted into manure which can be used in agricultural lands to grow crops or plants. So, composting is a very useful method contributing in crop farming.
(ii) When any foreign particles like disease-causing microbes enter into our body, WBCs immediately squeeze out of walls of blood capillaries and reach the site of infection and fight against the germs. Thus, abnormally a large number of WBCs in the blood are usually an indication of some infection in our body.
(iii) Flies are main carriers of germs as they sit on excreta which cause various diseases like cholera, typhoid, dysentery etc. If food will remain uncovered, the flies carrying these disease-causing germs will sit on our food, thus contaminating it and when we consume this contaminated food, we may suffer from various diseases. So, eating places should be free from flies.
(iv) The breathing process is involuntary i.e., not under the control of our will. To some extent we can increase or decrease the rate of breathing but after that we can not hold our breathe forcibly. Our respiratory centre is located in medulla oblongata which is stimulated by carbon dioxide concentration in our body. If we hold our breathe, carbon dioxide gas cannot be released to outside, so its concentration increases which will stimulate our respiratory centre.
(v) Food wall or oesophagus is soft so when there is no peristalsis process, it gets collapsed.
(b) Study the diagram given below and answer the following questions :
(i) Define the process shown in the figure above.
(ii) In which part of the alimentary canal does this process occurs ?
(iii) Is any enzyme secreted by the structure shown in above figure ? If yes, name it.
(iv) Sometimes reverse of the process named by you in Q. (i) occurs. Name the process and state why it occurs ?
(v) Name a structure which prevents backflow of food from :
1. Stomach to oesophagus.
2. Duodenum to stomach.
Answer:
Peristalsis is a wave of constriction caused by circular muscles of gut which pushes the food down into stomach.
It occurs in all regions of gut mainly in oesophagus.
No, oesophagus does not secrete any enzyme.
Antiperistalsis occurs when stomach is disturbed or overloaded where reverse wave of muscular contraction occurs causing throwing of food contents out from the mouth.
1. Cardiac sphincter
2. Pyloric sphincter.
Question 5.
(a) Define the following terms :
(i) Digestion
(ii) Sunstroke
(iii) Cellular respiration
(iv) Spawning of mushroom
(v) Bioweapons
Answer:
(i) Digestion is a process of conversion of complex food substances into smaller, simpler, diffusible molecules so that they can be absorbed and assimilated by our body.
(ii) Sunstroke is a condition in which sweat production is unable to keep pace with its evaporation in very hot winds, resulting in rise of body temperature which sometimes may prove fatal.
(iii) The complex chemical reactions which occurs inside a cell to release energy from glucose is called cellular respiration.
(iv) Spawning is the process of introduction of mushroom seed consisting of mycelium of selected type of mushroom into compost from which mushrooms will grow.
(v) Bioweapons are harmful biological agent like bacteria, virus, fungi which can cause diseases and may take epidemic shape killing living organisms. Example—Anthrax bacteria is used as bioweapons.
