EMRS PGT Biology Mock Test - 3 - EMRS MCQ

The focal length of a plane mirror is infinity. A plane mirror can be considered as a spherical mirror of infinite radius of curvature. Focal length is half of the radius of curvature and hence it is infinity.

This equation explains the behaviour of real gases with great accuracy and also the deviations of gas laws from ideal behaviour. The equation was proposed in the year 1873. It was a first step towards taking into account interaction forces which are acting between real gases molecules.

Saturated carbon compounds can form Straight and Branched types of chain structures.

• Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms.
• Each carbon atom is bonded to as many hydrogen atoms as possible.

• The Plasma cells of connective tissue secrete antibiotics.

Every one degree shift of longitude corresponds to 4 minute time difference.

So a time difference of 1 hour (60 minute) will have:

1 degree = 4 minutes

So, 60/4 = 15 and 15 × 1° = 15°

Now for 2 hours (120 min)

1 degree = 4 minutes

120/4 = 30 and 30 × 1° = 30°

So a time lag of 2 hours corresponds to 30 degrees of longitudinal change.

This follows from a simple fact that 360∘ ⇒ 24 hour.

Which is same as 360° ⇒ 1440 min. So 1° ⇒ 1440360 = 4 minutes.

Given statement: P > S ≥ M = L < J = N

I. L < N → True (as L < J = N)

II. P > M → True (as P > S ≥ M)

III. S = L → False (as S ≥ M = L gives either S = L or S > L)

Hence, both conclusions I and II are true.

Since all the harmoniums are instruments and all instruments are flutes, then flutes include instruments and harmoniums. And instruments include harmoniums.
(i) All flutes cannot be instruments, because instruments are flutes, but flutes can contain something else as well.
(ii) All the harmoniums are flutes because harmoniums are instruments and instruments are flutes.

Rahul’s position 14th from front
John’s Position 17th from last 
Alisha is between them


People between them 48 – (14+17) = 17
Where the midmost is Alisha 
So she has 8 people on either of her side.

So Option A is correct

(7 x 3) + 8 = 29

(4 x 3) + 7 = 19

(5 x ?) + 6 = 31

? = 5.

(12)² - (8)² = 80

and (16)² - (7)² = 207

Therefore (25)² - (21)² = 184.

As 'smoke' leads to 'pollution' in the same way ''War'' leads to 'destruction'.

C is the correct option.In the given coded word each constant is substituted by preceding constant and each vowel is also substituted by preceding vowel. Hence, SCHOOL will be codes as RBGIIK.

The primary purpose of software is to turn data into Information. ... Information is usually the processed outcome of data. When data is processed into information, it becomes interpretable and gains significance.

Correlational Method
The psychologist in this scenario is using the correlational method to study the individuals and compare the jobs they were employed in. The correlational method is a research technique used to examine the relationship between two or more variables.

1. Correlational Method: The correlational method involves studying the relationship or association between two variables without manipulating them. It aims to determine whether a relationship exists between variables and the strength and direction of that relationship.
2. Studying Individuals: In this case, the psychologist is studying individuals, which means they are examining the characteristics, behaviors, or other factors related to each person. The focus is on understanding the relationship between the individuals' job choices and their other characteristics or behaviors.
3. Comparison of Jobs: The psychologist is specifically comparing the jobs in which the individuals are employed. They might be interested in understanding how different factors, such as personality traits, education level, or socioeconomic status, influence the types of jobs people choose.
4. Variable Comparison: The psychologist will collect data on the individuals' job titles, industries, or other relevant information related to their employment. This data will be used to compare the job variables across the individuals in the study.
5. Quantitative Analysis: To determine the relationship between the variables, the psychologist will analyze the data using statistical techniques. They may use techniques like correlation analysis to measure the strength and direction of the relationship between variables.
6. Interpretation of Results: Based on the analysis, the psychologist will interpret the results and draw conclusions about the relationship between the individuals and the jobs they are employed in. They may find positive correlations, negative correlations, or no significant relationship between the variables.

• Emotional Needs of a Child:
  Appreciation, love, and affection are essential components of a child's emotional needs. These needs fall under the category of emotional well-being and play a crucial role in the child's overall development and happiness.
• Importance of Emotional Needs:
  Meeting a child's emotional needs is vital for their healthy growth and development. Emotional well-being helps in building a strong foundation for a child's self-esteem, resilience, and ability to cope with challenges. When a child feels loved, appreciated, and receives affection, they are more likely to develop a positive self-image and have healthier relationships with others.
• Appreciation:
  Appreciation refers to recognizing and valuing a child's efforts, achievements, and qualities. Expressing genuine appreciation helps a child feel acknowledged and valued. It boosts their self-confidence and motivates them to continue their efforts, whether it is in academics, sports, or any other area of their life.
• Love:
  Love is an essential emotional need for a child. It involves showing care, warmth, and affection towards the child. Expressing love through hugs, kisses, kind words, and spending quality time together helps the child feel secure, nurtured, and valued. Love provides a sense of belonging and creates a safe emotional environment for the child to grow and explore their own emotions.
• Affection:
  Affection is the physical expression of love and care towards a child. It includes physical touch, such as hugs, cuddles, and gentle gestures. Affectionate touch releases hormones like oxytocin, which promotes feelings of bonding, trust, and emotional well-being in a child. Regular affectionate interactions with parents or caregivers contribute to the child's emotional development and help them feel loved and secure.

The morphine/morphia is a white crystalline, bitter narcotic and principal alkaloids of Opium (Papaver somniferum).

Morphine is a benzylisoquinoline alkaloid with two additional ring closures. It has:

A rigid pentacyclic structure consisting of a benzene ring (A), two partially unsaturated cyclohexane rings (B and C), a piperidine ring (D) and a tetrahydrofuran ring (E). Rings A, B and C are the phenanthrene ring system. This ring system has little conformational flexibility.

Two hydroxyl functional groups: a C3-phenolic OH (pKa 9.9) and a C6-allylic OH,

An ether linkage between C4 and C5,

Unsaturation between C7 and C8,

A basic, tertiary amine function at position 17,

5 centers of chirality (C5, C6, C9, C13 and C14) with morphine exhibiting a high degree of stereoselectivity of analgesic action.

Morphine meconate is a major form of the alkaloid in the poppy, as is morphine pectinate, nitrate, sulphate, and some others. Like codeine, dihydrocodeine and other (especially older) opiates, morphine has been used as the salicylate salt by some suppliers and can be easily compounded, imparting the therapeutic advantage of both the opioid and the NSAID; multiple barbiturate salts of morphine were also used in the past, as was/is morphine valerate, the salt of the acid being the active principle of valerian. 

Shock is to surprise someone in an unexpected or unwanted way. It represents chaos whereas calm means to stay composed and stay cool.

Here’s the solution with a detailed explanation:

Sentence: Each one of the government hospitals are full at this point of time.

Error Identification:

• The phrase "Each one of the government hospitals" uses "each" as a singular subject. Therefore, the verb that follows should also be singular.

Correct Version:

• It should be: "Each one of the government hospitals is full at this point of time."

Explanation:

• "Each one" indicates that we are talking about individual items (in this case, hospitals), so it requires a singular verb ("is" instead of "are").

Final Answer:

• The error is in part 2.

The correct option is 2.
The sentence talks about a rich man killing himself and his own children. From the phrase, ‘his own children’, we can derive that the ‘him’ in the sentence refers to the rich man. The phrase is wrong as it should be ‘himself’ instead of ‘him’.
