Read the following statements :A) Mammalian lungs are solid and spongyB) In embryo state breathing rate and residual air are absentC) Residual volume is expelled only by force full expirationD) Partial pressure of oxygen in expired air is more than in inspired airHow many statements are correct ?1. 3 2. 43. 24. 1

Answer»

I think that option 4 is correct

because mammalian lungs are not solid(they contain air sacs = alveoli) but they are spongy,

statement 2 is correct for that you have to read sub-topic circulation in foetus of std 12 combining with concepts of respiration and circulation of std 11

statement 3 is wrong as residual volume is never expelled out of body,we can expell on expiratory reserve volume through forceful respiration as if we expire RV then there will be vacuum created in lungs and they will collapse

statement 4 is also wrong

Why are fossils considered important in the study of evolution? Explain two ways by which age of fossils can be estimated.

Answer»

Scientists combine several well-tested techniques to find out the ages of fossils. The most important are Relative Dating, in which fossils and layers of rock are placed in order from older to younger, and Radiometric Dating, which allows the actual ages of certain types of rock to be calculated.

Main topics covered in this part of CBSE Class 9 Science, Why Do We Fall Ill: Chapter Notes, are:

  • Health
  • Disease and its Types
  • Causes of disease
  • Antibiotics
  • Principle of Treatment
  • Principles of Prevention

Key notes for Chapter - Why Do We Fall Ill, are:

Health

Health is a state of complete physical, mental and social wellbeing.

Disease

Any disturbance in the structure or function of any organ or part of body.

It may be caused due to the attack of pathogens (virus, bacteria), lack of nutritious diet/balanced diet and lack of public health services.

Types of Disease

Diseases are basically of two types. They are:

(i) Acute Disease

The disease which lasts for only a short period of time is called Acute Disease.

For example: Influenza (Flu) , Common cold, etc.

(ii) Chronic Disease: The disease which lasts for long period of time is called Chronic Disease

For example: TB, Cancer, etc.

Difference between Acute Disease & Chronic Disease

S. No.

Acute Disease

Chronic Disease

 

1.

They are short duration disease

They are long lasting disease

2.

Patient recovers completely after the cure

Patient does not recover completely

3.

There is no loss of weight or feeling of tiredness afterward

There is often loss of weight of feeling of tiredness

4.

There is short duration loss of work and efficiency

There is a prolonged loss of work and efficiency

Causes of Diseases: 

Causes of diseases are explained below:

Immediate and Contributory Cause

  • Immediate cause: The organisms that enter our body and causes disease is called immediate cause. For example, virus, bacteria, protozoa etc.
  • Contributory cause: The secondary factors which led these organisms enter our body are called as contributory cause. For example, dirty water, contaminated food, improper ourishment, poor standard of living etc.

Infectious and Non-infectious Cause

Infectious causes: They include the agents like microbes or micro-organisms as the immediate causes which spread the disease from an infected person to a healthy person.

Non-infectious causes: The disease which does not spread by contact between infected and healthy person through air and water, is called non-infectious disease.

Infectious and Non-infectious Diseases

Infectious Diseases: The diseases which spread due to infection by micro-organisms are called infectious diseases.

When a disease causing organism enters our body it causes infection, it multiplies and grows in the body called host and micro-organisms multiplies in the host body.

For Example: Tuberculosis, tetanus, Common cold, AIDS, etc.

Non-infectious Diseases: The disease which does not spread by contact between infected and healthy person through air and water, is called non-infectious disease.

For example: Cancer, genetic abnormalities, high blood pressure, etc.

Means of Spreading Infectious Diseases:

S. No.

Type of Disease

Example

1.

Air born Diseases

Common cold, influenza, measles, tuberculosis.

2.

Water born diseases

Cholera, typhoid, hepatitis.

3.

Sexual Diseases

AIDS, Syphilis.

4.

Animal born Disease

Rabbis.

Antibiotics

These are the chemicals (medicine, drugs) that block biochemical pathways important for bacteria. They are used for diseases caused by bacteria.

Antibiotics do not work against viral infections as the viruses do not have their own biochemical mechanisms but depend upon that of the host.

Principles of treatment
1. To reduce the effects of the diseases

By taking medicines to bring down the effects of the disease like fever, pain, etc. and by taking complete rest to conserve the body’s energy.

2. To kill the cause of the disease

By taking suitable antibiotics and drugs which kills the disease causing microbes.

Principles of Prevention
1. General method:

They involve (a) Preventing exposure against microbes (b) By boosting the immune system

(a) Preventing exposure against microbes can be done in following ways:

For air-born microbes we can prevent exposure by avoiding overcrowded places. For water-borne microbes we can prevent exposure by not using contaminated water.

For vector-borne infections we can prevent exposure by providing clean environment.

(b) By boosting the immune system:

Our immune system plays an important role in fighting against the microbes that enter our body. strengthening the immune system can help in preventing many diseases. 

So, proper nourishment or healthy diet that includes all the necessary nutrients as well as vitamins and minerals is necessary for better functioning of our immune system.

2. Specific method
It involves the prevention method directed against a particular disease.

It is done by immunisation which is the process of introducing a weakened pathogen inside the body of the host to make his/her immune system to produce antibodies against that particular disease so that the next time even if the disease will strike the host’s body with full vigor, the body will be able to protect itself with the help of these antibodies.

State the role of pancreatic juice in digestion of proteins.

Answer»

Pancreatic juice contains a variety of inactive enzymes such as trypsinogen, chymotrypsinogen, and carboxypeptidases which help in the digestion of proteins and the partially hydrolysed proteins, like proteoses and peptones, into dipeptides.
