The correct dosage of adult over-the-counter medicine a child can receive is given by a formula by Clark. The child's weight, in pounds, is divided by $150$, and the result is multi pounds lied by the adult dose of the medicine. A mother need to give her daughter acetaminophen, which has an adult dose of $ 1000$ milligrams. She does not know her daughter's exact weight, but she knows the weight is  and between $75 $ and $90 $pounds. Find the range of correct dosage, d, in milligrams of acetaminophen the daughter could receive.

  1. $50$
  2. $500$
  3. $1000$
  4. $1600$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Clark's formula is (weight/150) * adult dose. For 75 lbs: (75/150) * 1000 = 500 mg. For 90 lbs: (90/150) * 1000 = 600 mg. The range is 500 to 600 mg, making 500 the only viable option provided.

DDT concentration in the human body is?

  1. 0.3-0.7 ppm

  2. 1.3-3.1 ppm

  3. 13-31 ppm

  4. 30-70 ppm.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless and almost odorless crystalline chemical compound, an organochlorine, originally developed as an insecticide. Now the human body resides about high levels of DDT which is highly toxic to their health.
So the correct option is '13-31ppm'.

The approx. percentage of water in human body is:

  1. 80 %

  2. 65 %

  3. 70 %

  4. 40 %
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The approx. percentage of water human body is $70\%$. The average adult human body is $50-65\%$ water, averaging around $57-60\%$. The percentage of water in infants is much higher, typically around $75-78\%$ water, dropping to $65\%$ by one year of age. Body composition varies according to gender and fitness level because fatty tissue contains less water than lean tissue.

Carefully read the following information to answer the question -


An egg farmer is experimenting with different feed rations with the aim of increasing his production whilst reducing the cost of the feed per egg produced. The data from the two feeding experiments are given below.

Experiment 1

Protein concentration in feed (%) 10 11 12 13 14 15 16
Total vitamin level (mg/kg) 100 100 100 100 100 100 100
Cost of feed ration per 100 hens per day 6.00 7.00 7.50 8.00 8.50 8.75 9.00
Number of eggs per 100 hens per day 70 70 75 80 85 80 80

Experiment 2

Protein concentration in feed (%) 14 14 14 14 14 14 14
Total vitamin level (mg/kg) 50 75 100 125 150 175 200
cost of feed ration per 100 hens per day 8.00 8.25 8.50 8.75 9.00 9.25 9.50
Number of eggs per 100 hens per day 70 80 85 90 95 95 95


Which feed composition gives the least cost per egg produced?

  1. Protein concentration (%) - 16; Total vitamin level (mg/kg) - 100

  2. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 50

  3. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 100

  4. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In Experiment 1-At protein concentration 16% vitamin level 100, the cost of feed is 9.00 and the number of egg produced is 80 per 100 hens

In experiment 2 - At protein concentration 14%, vitamin level 150, the cost of feed is 9.00 and the number of eggs produced is 95, an increase of 15 per 100 hens.
So, the correct answer is 'Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150'

What are the independent variables in each of the two experiments?

  1. Experiment 1 - Maximum daily egg production; Experiment 2 - Maximum daily egg production

  2. Experiment 1 - Protein concentration in the feed; Experiment 2 - Total vitamin level in the feed

  3. Experiment 1 - Total vitamin level in the feed; Experiment 2 - Protein concentration in feed

  4. Experiment 1 - Cost of feed ration per egg produced; Experiment 2 -Cost of feed ration per egg produced
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In experiment 1 the protein concentration is controlled or changed. So as to check the effect on cost of feed ration and number of eggs produced. Therefore it an independent variable

In experiment 2 total vitamin level in the feed is controlled or changed. So as to check the effect on cost of feed ration and number of egg produced. Therefore it is an independent variable.
So, the correct answer is 'Experiment 1 - Protein concentration in the feed; Experiment 2 - Total vitamin level in the feed'

The normal range of urinary output per day in human adults is

  1. 50 ml

  2. 10 ml

  3. 400-2000 ml

  4. 200 ml
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The waste products from the blood are removed by the kidneys in the form of urine. This is done by filtering of the blood. In human adults, the normal range of urinary output is between 400 to 2000 ml daily. The amount of urine produced by the body depends on the health of the person.

Multiple choice evs - i excretion in living organisms other systems in the body excretory system in human human excretory organs

Average quantity of urea excreted daily humans per day is

  1. 10 - 15 g

  2. 25 - 30 g

  3. 40 - 50 g

  4. 100 - 500 mg
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The composition of urine in humans is 95% water, 2.5 % urea and 2.5% other waste. As urea is the major excretory waste humans are considered ureotelic., On an average, 25-30 g of urea is excreted out per day.

So, the correct answer is '25-30 g'.

  4. 2200
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Planning Commission of India historically defined the rural poverty line based on a minimum nutritional requirement of 2400 calories per person per day. This higher threshold for rural areas accounts for the more physically demanding nature of agricultural labor.
