NVS Lab Attendant Mock Test - 10 - Question 4

Which atmospheric layer contains Ions and helps in wireless communication?

Detailed Solution for NVS Lab Attendant Mock Test - 10 - Question 4

The correct answer is Thermosphere.

Key Points

The atmosphere consists of different layers with varying densities and temperatures. The column of the atmosphere is divided into five different layers depending upon the temperature condition.
They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The troposphere

  • It is the lowest part of the Earth's atmosphere in which all tropical changes take place. It contains about 75% of the total air in the atmosphere.
  • This layer contains dust particles and water vapor.
  • All changes in climate and weather take place in this layer.
  • This is the most important layer for all biological activity.
  • The zone separating the troposphere from the stratosphere is known as the tropopause.
  • The temperature here is nearly constant, and hence, it is called tropopause.

The stratosphere

  • It is found above the tropopause and extends up to a height of 50 km.
  • One important feature of the stratosphere is that it contains the ozone layer.
  • This layer absorbs ultraviolet radiation and shields life on the earth from an intense, harmful form of energy.
  • The stratopause caps the top of the stratosphere.

The mesosphere

  • It lies above the stratosphere, which extends up to a height of 80 km.
  • In this layer, once again, the temperature starts decreasing with the increase in altitude and reaches up to minus 100°C at a height of 80 km.
  • The upper limit of the mesosphere is known as mesopause.

The thermosphere 

  • It is located between 80 and 400 km above the mesopause.
  • It contains electrically charged particles known as ions, and hence, it is also known as the ionosphere.
  • Radio waves transmitted from the earth are reflected back to the earth by this layer.
  • It contains Ions and helps in wireless communication
  • The temperature here starts increasing with height.

The exosphere

  • It is the uppermost layer of the atmosphere.
  • This is the highest layer but very little is known about it.
  • Whatever contents are there, these are extremely rarefied in this layer, and it gradually merges with outer space.

NVS Lab Attendant Mock Test - 10 - Question 15

Directions: In the following question, a sentence is given with a blank. You have to fill the blank with one of the words given as options in order to make the sentence contextually and grammatically correct.

The recent protests in China happened for a variety of reasons _______________ from unfavourable working conditions to bank failures.

Detailed Solution for NVS Lab Attendant Mock Test - 10 - Question 15

Let us first learn the meanings of the given words:

Span (verb): extend across.

Extend (verb): cause to cover a wider area or make larger.

Vary (verb): differ in size, amount, degree, or nature from something else of the same general class.

Range (verb): extend between specified limits.

The idea here is to express that there was a huge range of reasons why the protests in China had started. Grammatically only a verb in ‘-ing’ form will fit the blank, this eliminates ‘span’, ‘extended’ and ‘vary’. Now, between ‘scoping’ and ‘ranging’, ‘ranging’ is a better option to be placed before ‘from’.

Hence, option d is correct.

  • Rising maximum and minimum temperatures.
  • Rising sea levels 
  • Higher ocean temperatures 
  • An increase in heavy precipitation (heavy rain and hail)
  • Shrinking glaciers
  • Thawing permafrost

The indirect consequences of climate change, which directly affect us humans and our environment, include: 

  • An increase in hunger and water crises, especially in developing countries.
  • Health risks through rising air temperatures and heatwaves. 
  • Economic implications of dealing with secondary damage related to climate change 
  • Increasing spread of pests and pathogens
  • Loss of biodiversity due to limited adaptability and adaptability speed of flora and fauna  
  • Ocean acidification due to increased HCO3 concentrations in the water as a consequence of increased CO2 concentrations.

NVS Lab Attendant Mock Test - 10 - Question 28

The cause of Astigmatism is

Detailed Solution for NVS Lab Attendant Mock Test - 10 - Question 28
What Causes Astigmatism?
Astigmatism is a common vision problem that occurs when the cornea or lens of the eye is irregularly shaped. This irregular shape prevents light from focusing properly on the retina, resulting in blurred or distorted vision. The exact cause of astigmatism is not fully understood, but there are several factors that may contribute to its development.
Causes of Astigmatism:
1. Varying Curvature in Horizontal Lines:
- One possible cause of astigmatism is an uneven curvature of the cornea or lens in the horizontal meridian.
- This means that the cornea or lens is steeper in one direction (horizontal) than in the other (vertical), causing light to focus differently in each direction.
- This can result in blurred vision at both near and far distances.
2. Varying Curvature in Vertical Lines:
- Another possible cause of astigmatism is an uneven curvature of the cornea or lens in the vertical meridian.
- This means that the cornea or lens is steeper in one direction (vertical) than in the other (horizontal), causing light to focus differently in each direction.
- Similar to horizontal astigmatism, this can result in blurred vision at both near and far distances.
3. Combination of Both:
- In some cases, astigmatism can be caused by a combination of varying curvatures in both the horizontal and vertical meridians.
- This means that the cornea or lens has irregularities in multiple directions, leading to distorted vision in various orientations.
4. Other Factors:
- Astigmatism can also be associated with other eye conditions, such as keratoconus (cone-shaped cornea) or corneal scars.
- In some cases, astigmatism may be present from birth (congenital) or develop later in life due to eye injury, surgery, or certain diseases.
Conclusion:
In conclusion, the cause of astigmatism is typically an irregular shape of the cornea or lens, resulting in varying curvature in horizontal, vertical, or both directions. It is important to consult an eye care professional for a comprehensive eye examination to determine the exact cause and severity of astigmatism, as well as to discuss appropriate treatment options.
NVS Lab Attendant Mock Test - 10 - Question 29

Detailed Solution for NVS Lab Attendant Mock Test - 10 - Question 29

A large force that acts in a very short duration of time is reffered to as impulsive force. This force which is large due to a high speed such as kick of a football may be disastrous as the momentum change is large and hence a goalkeeper holds his hand backwards in order to reduce the force exerted on his hands.

NVS Lab Attendant Mock Test - 10 - Question 30

When the foetus is growing inside the uterus it needs nutrients. Which part provides these nutrients?

Detailed Solution for NVS Lab Attendant Mock Test - 10 - Question 30
Placenta is the part that provides nutrients to the growing fetus inside the uterus.
Explanation:
The placenta is an organ that develops during pregnancy and is attached to the inner wall of the uterus. It acts as a connection between the mother and the fetus, providing essential nutrients and oxygen to support the growth and development of the fetus.
Key Points:
- The placenta is responsible for exchanging nutrients and waste products between the mother's blood and the fetus's blood.
- It allows the transfer of oxygen, glucose, amino acids, vitamins, and minerals from the mother's bloodstream to the fetus.
- The placenta also filters out waste products such as carbon dioxide and urea from the fetus's blood, which are then eliminated by the mother's body.
- It produces hormones that help maintain the pregnancy, such as human chorionic gonadotropin (hCG), progesterone, and estrogen.
- The placenta also acts as a protective barrier, preventing harmful substances from reaching the fetus.
- It continues to grow and develop throughout pregnancy, ensuring a constant supply of nutrients and oxygen to support the fetus's growth.
In conclusion, the placenta plays a crucial role in providing the necessary nutrients for the growing fetus inside the uterus.
