NVS Lab Attendant Mock Test - 2 - Question 2

Direction: Study the following information and answer the given questions carefully.
There are 8 persons, P, Q, R, S, T, U, V and W sitting around a rectangular table in such a way that four of them sit at four corners of the table while four sit in the middle of each of four sides. Persons who sit at the corners face outside the centre while those who sit in the middle of the side face inside.
Q sits second to the right of P. R sits third to the left of W. R faces inside. T sits third to the left of U. V sits second to the left of U. R is not an immediate neighbor of P.
Q. Four of the following five are alike in some manner hence belong to a group. Find the one that doesn’t belong to that group.

Detailed Solution for NVS Lab Attendant Mock Test - 2 - Question 2

From the final arrangement, we get, R doesn’t belong to that group as except for R, all the others are facing outside.
Hence, Option D is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

NVS Lab Attendant Mock Test - 2 - Question 17

Consider the following statements with respect to Ecological Pyramid:

1. The pyramid of biomass in a sea is generally inverted.

2. The pyramid of energy in any ecosystem can never be inverted.

Which of the statements given above is/are correct? 

Detailed Solution for NVS Lab Attendant Mock Test - 2 - Question 17

The correct answer is Both 1 and 2.

Key Points

  • In most ecosystems, all the pyramids, of the number, of energy, and biomass are upright, i.e. producers are more in number and biomass than the herbivores, and herbivores are more in number and biomass than the carnivores.
    • Also, energy at a lower trophic level is always more than at a higher level.
    • However, there are exceptions to this generalization
      • The pyramid of biomass in the sea is generally inverted because the biomass of fishes far exceeds that of phytoplankton.

  • Hence statement 1 is correct.
  • A pyramid of energy is always upright, can never be inverted, because when energy flows from a particular trophic level to the next trophic level, some energy is always lost as heat at each step.
    • Each bar in the energy pyramid indicates the amount of energy present at each trophic level in a given time or annually per unit area.

  • Hence statement 2 is correct.
NVS Lab Attendant Mock Test - 2 - Question 18

Name the disease which is likely to be caused due to ozone depletion

Detailed Solution for NVS Lab Attendant Mock Test - 2 - Question 18
Disease caused by ozone depletion:
- Skin cancer: Ozone depletion leads to an increase in ultraviolet (UV) radiation reaching the Earth's surface. UV radiation can damage the DNA in skin cells, leading to the development of skin cancer. Excessive exposure to UV radiation, especially UVA and UVB rays, increases the risk of developing skin cancer.
- Lung cancer: Although ozone depletion does not directly cause lung cancer, it indirectly contributes to the development of lung cancer. Ozone depletion can worsen air pollution, which is a major risk factor for lung cancer. Increased levels of air pollutants, such as particulate matter and toxic gases, can increase the risk of developing lung cancer.
- Respiratory disorders: Ozone depletion can also lead to respiratory disorders due to increased levels of air pollutants. Inhalation of pollutants such as nitrogen oxides, sulfur dioxide, and volatile organic compounds can cause respiratory irritation, inflammation, and damage to the respiratory system. This can lead to the development or exacerbation of respiratory disorders such as asthma, bronchitis, and chronic obstructive pulmonary disease (COPD).
- All of these: Considering the impacts of ozone depletion on skin cancer, lung cancer, and respiratory disorders, it can be concluded that all of these diseases are likely to be caused or exacerbated by ozone depletion.
In summary, ozone depletion can contribute to the development of skin cancer, lung cancer, and respiratory disorders due to increased UV radiation, worsened air pollution, and the inhalation of pollutants. It is important to take measures to protect ourselves from excessive UV radiation and address the causes of ozone depletion to minimize the health risks associated with it.
