  1. NCD can be treated whereas CD cannot

  2. CD can spread to others whereas NCD cannot

  3. CD can be treated whereas NCD cannot

  4. NCD can spread to others whereas CD cannot

Show answer
Correct Option: B
Explanation:

Explanation: Communicable diseases are caused by pathogens passed from one human to another. Non-communicable disease (NCD) is a medical condition or disease that is non-infectious or non-transmissible.

The following are all methods to prevent the spread of communicable disease EXCEPT:

  1. Washing your hands before you eat

  2. Sneezing into the inside or your arm or into a tissue

  3. Going outside and getting some sun

  4. Avoid touching your face or mouth

Show answer
Correct Option: C
Explanation:

Communicable diseases are caused by pathogens passed from one human to another. Use soap, warm water and disposable paper towels. Wash your hands frequently and avoid direct contact.

Which one of the following is a communicable disease?

  1. Measles

  2. Cancer

  3. Heart stroke

  4. Allergy

Show answer
Correct Option: A
Explanation:
Communicable diseases are the ones that can spread from the infected person to a healthy person.
Measles is caused by a virus which is rubella virus. It is characterized by fever, inflammation of nasal mucous membrane, red watery eyes sensitive to light, flushed face followed by a typical rash. The incubation period is about 10 days. It is a communicable disease and can transfer from one individual to another.
Hence, the correct answer is 'Measles'

Which one of the following hormone has potential to prevent certain chronic disease like cancer and multiple sclerosis?

  1. Melatonin

  2. Testosterone

  3. Estrogen

  4. Dehydro-epiandro sterone

Show answer
Correct Option: D
Explanation:

Dehydroepiandrosterone (DHEA) is an important endogenous steroid hormone. It is the most abundant circulating steroid hormone in humans. DHEA is used to treat systemic lupus erythematosus (SLE), osteoporosis, multiple sclerosis (MS), low levels of steroid hormones (Addison disease), depression, schizophrenia, chronic fatigue syndrome (CFS), and to slow the progression of Parkinson disease. It is also used for preventing heart disease, breast cancer, diabetes, and metabolic syndrome. DHEA is used for weight loss, for decreasing the symptoms of menopause, and for boosting the immune system. It is naturally produced in the human body.

So, the correct answer is option D.

Energy currency/coin of cell is

zoology respiration and energy transfer active transport and passive transport types of plant transport atp

  1. ATP

  2. NAD

  3. ADP

  4. GDP

Show answer
Correct Option: A
Explanation:

ATP is adenosine triphosphate. It is formed of an adenine, a ribose and three phosphate radical attached to ribose. It is a storehouse of energy. It is found in all living cell. ATP is called energy currency as well as an energy carrier of the cell. ATP usually obtains energy during respiration. It provides energy for membrane transport, nerve conduction, cell movement, cell division etc. Breakage of one phosphate bond in the presence of ATP-ase and releases of 8.9Kcal per mole. Thus, the correct option is A.

Which of the following is energy rich compound formed in cellular respiration?

  1. ADP

  2. Glucose

  3. Water

  4. ATP

  5. Oxygen

Show answer
Correct Option: D
Explanation:

During cellular respiration, the energy formed in mitochondria is stored in the form of ATP which is also known as energy currency of the cell. It provides energy for all the life activities by its breakdown into ADP and Pi. ATP contains three phosphate group which has high energy bond. On the hydrolysis of ATP energy is released and ADP formed.

Which one of the following is known as energy currency of cell?

  1. Adenosine diphosphate

  2. Adenosine triphosphate

  3. Pyruvate

  4. Glucose

Show answer
Correct Option: B
Explanation:

Adenosine triphosphate (ATP) is known as the energy currency of the cell. There are three phosphate bonds which store a large amount of energy. When these bonds are broken down, the energy is released. The energy is used to carry out biochemical reactions in the cell.

Thus, the correct answer is option B. 

ATP was discovered by

zoology respiration in organisms active transport and passive transport types of plant transport atp

  1. Lipmann

  2. Lohmann

  3. Blackman

  4. Bowman

Show answer
Correct Option: B
Explanation:

ATP is known as energy currency of the cell and it is a nucleotide formed by the combination of adenine as a nitrogenous base, ribose sugar, and triphosphate. It is found in free cells which breaks to form energy by breaking its high energy phosphate bonds. Karl Lohmann was first to discover ATP. It is produced by the mitochondria in the cell.

So, the correct answer is option B.
