Multiple choice basics of management of water environmental science conservation of resources food production: soil and water management biology

______________ are used for converting saline or brackish water into pure distilled water.

  1. Photo voltaic cells

  2. Solar desalination systems

  3. Solar cookers

  4. Solar water-heating
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Solar desalination systems use solar energy to evaporate saline or brackish water, leaving salts behind and condensing the pure water vapor.

.......... is used in seeding clouds.

  1. Potassium iodide

  2. Calcium carbonate

  3. Sulphur dioxide

  4. Ammonium phosphate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • An artificial method of rain is called seeding cloud. It is a type of weather modification. 
  • This method aims at to change the amount of precipitation which falls from clouds. The method uses seeding of certain substances into the air that will serve as cloud condensation. 
  • In this, tiny particles like potassium iodide or dry ice are seeded (sprayed) in the atmosphere. 
  • The water present in the air is attracted and condenses near the sprayed particles. 
  • It further crystallises to form ice. Finally, it causes the rainfall. 
  • Thus, the correct answer is option A.

Which of the following tissue is not found in the skin of man ?

  1. Epithelial tissue

  2. Areolar tissue

  3. Dense fibrous connective tiisue
  4. Both $(1)$ and $(3)$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Epithelial tissues line the outer surface of organs and blood vessels throughout the body, as well as the inner surface of cavities in many internal organs. The human skin has up to seven layers of ectodermal tissues and guards the underlying muscles, Bones, etc.

The skin consist of $3$ layers of tissues, the epidermis an outer most layer the contains the primary protective structure, the stratum corneum, the dermis, a Fibrous layer that supports and strengthens the epidermis; and the subcutis.

Each myoglobin binds with ________________.

  1. One molecule of $O _2$
  2. $4$ molecule of $O _2$
  3. Two molecules of $O _2$
  4. $3$ molecules of $O _2$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Myoglobin is similar to hemoglobin in a way that both are oxygen-carrying protein but in a different location. It can bind to only one molecule of oxygen because it is a monomeric protein.

So the correct option is "One molecule of $O _2$".

Loss of water from body occurs by all of the following except

  1. Muscles

  2. Lungs

  3. Kinney

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

Water loss from the body occurs through lungs (respiration), kidneys (urine), and skin (sweat). Muscles are not a route for water excretion - they're tissues that store water, not eliminate it. The option C has a typo (Kinney instead of Kidney).

In transgenics, expression of transgene in target tissue is determined by ____________.

  1. Reporter

  2. Enhancer

  3. Transgene

  4. Promotor
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In transgenic organisms, the promoter is the DNA sequence that initiates the transcription of the transgene, thereby determining where and when the gene is expressed.

Which of the following option is not related with the other three options?

  1. Keratin

  2. Elastin

  3. Dextrin

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

Keratin is a family of fibrous structural proteins. It is the protein that protects epithelial cells from damage or stress that has potential to kill the cell.

Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting.
Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch or glycogen. 
Collagen is the main structural protein in the extracellular space in the various connective tissues in animals.
As Dextrin is a carbohydrate, whereas rest others are proteins, hence it is unrelated. Hence, option C is correct.

The muscle fatigue occurs due to accumulation of

  1. ${ CO } _{ 2 }$

  2. Lactic acid

  3. Creatine phosphate

  4. Myosin ATPase
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Aerobic respiration gives more energy but is a slow process. Anaerobic respiration like lactic acid fermentation is a fast process but releases less energy. In the case of rapid muscular contraction, the muscles perform lactic acid fermentation to provide for rapid energy intake. This process releases lactic acid which causes pain and muscle fatigue. So, the correct answer is option B.
