  4. $30-33$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
  • The Normal range of breathing rate per minute in an average adult person at rest is 15-18.
  • So, the correct answer is '15-18'.

Multiple choice biology body fluids and circulation cardiac disorders cardiac regulation and disorders the blood system

What is correct regarding blood pressure?

  1. 105/50 mm Hg makes one very active

  2. 100/55 mm Hg is considered at ideal blood pressure

  3. 190/110 mm Hg may harm vital organs like brain and kidneys

  4. 130/90 mm Hg is considered as high and requires treatment
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Blood pressure 190/110 mm Hg indicates high blood pressure or hypertension. Normal systolic and diastolic blood pressure in body is 140 mm Hg and 90 mm Hg respectively. Pressure above 140 mm Hg and 90 mm Hg is high blood pressure which can cause damage to vital organs like brain and kidney. High blood pressure can cause damage to blood vessels in brain and kidney. This can lead to rupture of blood vessels and cause brain haemorrhage. In kidneys, high blood pressure can lead to inadequate supply of blood to kidney and thus, resulting in decreased filtration.
So, the correct answer is '190/110 mm Hg may harm vital organs like brain and kidneys'.

Multiple choice biology transportation in plants and circulation in animals heart beat cardiac cycle heart, blood vessels and cardiac cycle

An adult human with average health has systolic and diastolic pressures as

  1. 120 mm Hg and 80 mm Hg

  2. 50 mm Hg and 80 mm Hg

  3. 80 mm Hg and 80 mm Hg

  4. 70 m Hg and 120 mm Hg
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Blood pressure is the pressure against the walls of the blood vessels produced by the discharge of blood into them by contraction of the left ventricle.

Systolic pressure: The temporary rise in BP during the contraction of the heart is called systolic pressure.
Diastolic pressure: The temporary fall in BP during the relaxation of the heart is termed as diastolic pressure.
For a healthy resting adult person, the average systolic/ diastolic pressures are 120/80 mm Hg in arteries near the heart.
So, the correct answer is '120 mm Hg and 80 mm Hg'.

Multiple choice zoology soil pollution industrial chemicals and their harmful effects toxic wastes and their effects soil pollution-causes

The bioconcentration of DDT in the body fat of Indian people is

  1. 18-36 ppm

  2. 5-10 ppm

  3. 13-31 ppm

  4. 2-5 ppm
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Most of organochlorine pesticides are highly soluble in fat of animals. Further, these chemicals are resistant to be metabolized, so they start accumulating in the bodies of animals. 

In India due to prolonged use of DDT, 13-31 ppm of DDT can be detected in the body fat of people, which is highest in the world. Thus, the correct answer is option C.

The given table shows the result of intravenous injection of substances to determine the effect of each substance on normal body variables. An appropriate amount of time was allowed between injections and the substances did not interfere with one another. 

Variable Baseline values Values after injecting substance A Values after injecting substance B Values after injecting substance C Values after injecting substance D
Serum ${ Ca }^{ ++ }$ 2.3mmol/L 2.3mmol/L 2.3mmol/L 3.0mmol/L 2.3mmol/L
Serum ${ Na }^{ + }$ 135mmol/L 135mmol/L 135mmol/L 136mmol/L 135mmol/L
Serum glucose 5.6mmol/L 3.3mmol/L 5.6mmol/L 7.4mmol/L 5.6mmol/L

The normal release of substance D will be

  1. Soon after a meal.

  2. When blood pressure is low.

  3. Between meals.

  4. When there has been limited intake of dietary calcium.

  5. When dietary calcium is in excess.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

After intravenous injection of substance D, it is seen that there is no change in the baseline values of calcium, sodium and glucose level. When the blood pressure is low it will be released, so that the blood pressure is maintained by regulating sodium, calcium and glucose level.

So, the correct answer is option B.
