SRMJEE Mock Test - 1 (Medical) - JEE MCQ

∴ 2/T = 2 or T = 1h

Focal length of the objective lens, f_o = 144 cm
Focal length of the eyepiece, f_e = 6.0 cm
The magnifying power of the telescope is given as:

= 24
The separation between the objective lens and the eyepiece is calculated as:
f_o + f_e 
= 144 + 6
= 150 cm
Hence, the magnifying power of the telescope is 24 and the separation between the objective lens and the eyepiece is 150 cm.

The resistance of a conductor is, 

Here, V = Al is the volume of the wire. As both the wires are made of copper, their densities are same.
Hence, mass of the wire is directly proportional to the volume.
Let l₁ & l₂ be the lengths of the two wires and m₁ & m₂ be their masses, respectively.

Given that, 

From equation (1)1, we can write,

The convection is process of heat transfer via medium but when glass surface is heated due to filament of bulb, it heated only due to radiation. It is because when glass bulb is manufactured, inside glass bulb, vacuum is maintained means there is no medium inside the bulb.

(f₁)_max = between 1kg and 2kg


=0.2 × 1 × 10 = 2N

Reduction of one mole of to Cr⁺³ involves the transfer of six moles of electrons.
Required charge = 6 F = 6 × 96500 C [ one F = 96500 C]

SBR (styrene-butadiene rubber) is a polymer of two different monomers, so it is a copolymer.

CO₂ (sp) ⇒ Bond Angle = 180°
H₂O (sp³) ⇒ Bond Angle = 104° 5'
SO₂ (sp²) ⇒ Bond Angle = 119.5°
CH₃⁺ (sp²) ⇒ Bond Angle = 120°

Copper is found in native as well as in combined state , Fe,AI,Mg are more reactive than copper.

Primary aromatic amines react with nitrous acid to yield arene diazonium salts.

The diazonium group can be replaced by fluorine by treating the diazonium salt with fluoroboric acid (HBF₄)(HBF₄) .
The precipitated diazonium fluoroborate is isolated, dried and heated until decomposition occurs to yield the aryl fluoride.
This reaction is known as Blaz-Schiemann reaction.

• A. Neutrophils are responsible for phagocytosis of foreign organisms.
• B. Basophils release histamine during inflammation.
• C. Eosinophils play a role in defense against parasitic infections.
• D. Lymphocytes are responsible for the production of antibodies.

Thus, the correct matching is Option 1: A - R, B - Q, C - P, D - S

During the first pregnancy, the maternal immune system is not yet sensitized to the Rh antigen, so the mother produces antibodies against Rh only after exposure to the foetal blood during delivery. This is why the first pregnancy is generally unaffected.

• Statement 1 is correct: The endodermis in dicot roots contains Casparian strips made of suberin.
• Statement 2 is correct: The pericycle is responsible for the initiation of lateral roots and vascular cambium during secondary growth.
• Statement 3 is incorrect: The xylem in dicot roots typically has an exarch arrangement (with the xylem located towards the outside) rather than a polyarch condition.
• Statement 4 is correct: The pith in dicot roots is typically small or inconspicuous.

Thus, the correct answer is Option 1: 1, 2, and 4.

Prions are infectious agents composed of abnormally folded proteins. Mad cow disease (also known as Bovine Spongiform Encephalopathy) is a prion disease, where the prions cause brain damage in cattle. The prion's primary feature is its ability to induce misfolding of normal proteins in the brain, leading to neurological damage.

Red tides are caused by the rapid growth of dinoflagellates, which can release toxins that are harmful to marine life, including fish, shellfish, and other marine animals. These toxins can cause massive die-offs and can even be toxic to humans who consume contaminated seafood. Thus, Option 2 is correct, as it highlights the harmful effects of red tides as harmful algal blooms.

Bulliform cells are large, empty, and colourless cells found in the leaves of grasses. These cells help in controlling leaf rolling under water stress.

During double fertilization in plants one sperm fises with the egg cell and the other sperm fuses with two polar nucles of the central cell to produce triploid primary endospersm cell (3n). Since the latter involves fusion of three haploid nudeus therefore it is called triple fiixion.

The lymphocytes which differentiate in the thym us are known as the T - lymphocytes. T-lymphocytes are responsible for the cellular immune response.

The Southern blot is used to detect and identify certain DNA sequences in a sample of bodily fluid. It uses single-stranded DNA to search out their complementary strands. When a Southern blot is performed on DNA, the first step is digestion of DNA with restriction enzymes. Restriction enzymes cut DNA at known sequences, and produces DNA fragments of a certain length. Once the DNA is cut into pieces, scientists conduct electrophoresis to separate them by size.

Statements (i) and (iii) are correct.
Medical Termination of Pregnancy (MTP) during first trimester is generally safe.
Intrauterine device like copper-T are effective contraceptives.

In ΔABC, right angled at B, we get
sin A = BC/AC

sin 45° = 15/AC
AC = ft

D is the midpoint of BC.

⇒ BD = CD
Now, we have to find a : b.
tan q =
In ΔABD,
tan 60° =

BD = … (1)
Similarly, in ΔCDE,
tan 30° = ( CD = BD)
BD = b ... (2)
Thus, from equations (1) and (2), we get:
= b
Hence, a : b : : 3 : 1

Let the ten's digit be x and units digit be y.
Then, (10x + y) – (10y + x) = 63 ⇔ 9 (x – y) = 63 ⇔ x – y =7|
We can only find the difference of x and y, not about number.
Thus, none of the numbers can be determined.

The preposition along is used before nouns like road, river, corridor, line.
To talk about periods or activities, we prefer through. 
By this standard, the given sentence is wrong.
So, it should be replaced by 'All through the journey he remained with me.'
Thus, option C is the correct answer.

Believe - Accept that (something) is true.
Reveal - Make (previously unknown or secret information) known to others.
Disbelieve - Be unable to believe.
Agree - Have same opinion about something
Deny -  State that one refuses to admit the truth.
Since, antonym means opposite.
So, from above given meanings, we can conclude that, disbelieve is the antonym of believe.
Thus, option B is the correct answer.
