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.

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or grey in colour, depending on their mineralogy.

Only II and III

Generally, covalently bonded molecules are poor conductors of electricity and have weak intermolecular force.

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.

Option ( a) is the right answer.

"South -east "

If south-east becomes North and north east becomes west, therefore,the whole figure moves 135 degree. Hence, West will bw south east. see, actual figure is rotating 135 degree anticlockwise. So, whenwest will be retated by same degree anticlockwise. It will hold the place of south east.

According to the question,
N > M
Y > M
N > X > Y
On arranging the above data, we get
&becaul; N > X > Y > M
So, N is the most intelligent among them.

So Option A is correct

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

According to the question,
B > D
A and C > E
∴ B > D > A and C > E
Clearly, shortest = E

So Option A is correct

(7 x 3) + 8 = 29

(4 x 3) + 7 = 19

(5 x ?) + 6 = 31

? = 5.

As fast mode of 'Walk' is 'Run' in the same way fast mode of 'Breeze' is 'Wind'.

Clinical Case Study
A clinical case study is one of the procedures used by clinicians to develop case studies. This approach involves a detailed and comprehensive examination of an individual or a group of individuals who are undergoing a specific medical or psychological condition. The primary objective of a clinical case study is to understand the unique characteristics, symptoms, and treatment outcomes of the particular case being examined.
Procedure of a Clinical Case Study:

1. Selection of the Case: The clinician chooses a specific case that is relevant to their field of study or practice. This could be an individual or a group of individuals who exhibit particular symptoms or have undergone a specific treatment.
2. Data Collection: The clinician gathers comprehensive data about the case through various methods such as interviews, observations, medical records, psychological assessments, and laboratory tests. This data helps in understanding the background, symptoms, history, and other relevant factors associated with the case.
3. Analysis and Interpretation: The collected data is carefully analyzed and interpreted by the clinician. This involves identifying patterns, making connections, and drawing conclusions based on the information gathered. The clinician may use their professional expertise and knowledge to interpret the data accurately.
4. Formulation of a Case Study: The clinician then organizes and presents the findings of the case study in a structured and systematic manner. This includes providing an overview of the case, describing the symptoms, presenting the analysis and interpretation of the data, and discussing the treatment outcomes.
5. Publication and Peer Review: In many cases, clinicians may choose to publish their case studies in medical or psychological journals. These case studies undergo a peer review process where other experts in the field evaluate the quality, validity, and relevance of the study before publication.
6. Contributing to Evidence-Based Practice: Clinical case studies contribute to the body of knowledge in the field of medicine or psychology. They provide valuable insights into the diagnosis, treatment, and management of various conditions, which can help clinicians make informed decisions in their practice. 

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. 

The correct answer is 'who'. 'Who' is nominative and is used to refer to the subject. 'Whom' is objective and is used to refer to the object. The word 'whose' is possessive and is used to show belonging or association. The word 'which' is used for inanimate objects.
and in the given sentence you can see we are referring to a man who was on the continent so we are talking about the subject 
suppose the sentence is
The student, who  had lost miserably.
so in this we are talking about the student and not "you"
Example- This is Mr. Lee, who is the greatest martial art teacher of this era. But  Mr. Lee, whom you thought so highly of, has lost the fight.

'Back to square one' means to come back to the point where something was initially started.  Option 3 is thus absolutely correct.
Example- After the failure of the machine prototype, the team was back to square one.
