Multiple choice zoology our health introduction to health and disease health and its failure health and its significance

Which of the following factor affect human health? 
i. Infections 
ii. Silence mutation
iii. Life style 
iv. Genetic disorders 

  1. i, ii, iv

  2. i, ii

  3. i, iii, iv

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Infection is caused when a pathogen invades the tissue and proliferates. The pathogen rapidly destroys the cells of the host which adversely affect the immune system and cause infections.

Lifestyle choices affect cardiovascular, psychological, nutritional, skeletal and neurological health. For example, smoking and drinking alcohol in excess both lead to stroke, heart disease, and cancer. Eating a poor diet that is overly-processed and lacks nutritive quality leads to obesity, malnutrition, diabetes, heart disease and cancer. 
Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur, therefore does not affect human health.
A genetic disorder is caused by an altered or faulty gene or set of genes. These disorders can be found to affect any part of the body including the brain and the muscles. Therefore, out of the options, only 1, 3 and 4 affects human health. 
Therefore, the correct answer is option C.

Multiple choice biology food for health fats fats and their test different nutrients in food

Energy content of alcohol is $7.1kcal/gm$. it is more than carbohydrates and slightly less than fats. Intake of alcohol provides

  1. Enough energy to body for its working

  2. Releases heat energy

  3. Uses energy of body for dissipation of alcohol produced heat

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Alcohol metabolism releases energy as heat, but it also increases the body's metabolic rate and heat dissipation processes, which can lead to a net loss of body heat or energy imbalance.

Multiple choice biology biological molecules fats fats and their test food for health

How many calories does fat provide:

  1. 14 Kcal/g or 17 KJ/g

  2. 9 Kcal/g or 38 KJ/g

  3. 6 Kcal/g or 25 KJ/g

  4. 4 Kcal/g or 17 KJ/g.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Answer is option B i.e. "9 Kcal/g or 38 KJ/g"
A calorie is a unit of energy that measures how much energy food provides to the body. The body needs calories to function properly. Fats are nutrients in food that the body uses to build cell membranes, nerve tissue (like the brain), and hormones. A gram of fat has about 9 calories, while a gram of carbohydrate or protein has about 4 calories.

Multiple choice properties of enzyme enzyme properties enzymes biomolecules: chemical constituents of living cells biology

The action of lysozyme is

  1. Physiological

  2. Anatomical

  3. Morphological

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Lysozyme are also reffered as muramidase. They are glycoside hydrolases. They catalyzes hydorlysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetly-D-glucosamine residues in peptidoglycan thus they can dissolve bacterial cell wall. It is present  in a number of secretions, such as tears, saliva, human milk and mucus. So, its function is physiological.
Thus, the correct answer is option (A).

Multiple choice physics pressure in liquids and gases common consequences of the atmospheric pressure atmospheric pressure and its consequences important points about atmospheric pressure

A nurse measures the blood pressure of a seated patient to be $190$ mm of Hg.

  1. the blood pressure at the patient's feet is less than $190$ mm of Hg.
  2. the actual pressure is about $0.25$ times the atmospheric pressure.
  3. the blood pressure at the patient's neck is more than $190$ mm of Hg.
  4. the actual pressure is about $1.25$ times the atmospheric pressure.
