Explanation

Paramagnetism is due to the presence of one or more unpaired electrons which are attracted by the magnetic field

Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets.

Explanation

Mass 1,  = 1000 kg

Mass 2,  = 1000 kg

Distance between the spheres, r = 0.5 meters

Gravitational force is the force of attraction between two bodies.

The force of gravitation is inversely proportional to the square of the distance between the bodies and directly proportional to the multiplication of masses of two bodies.

It is given as:

F= G (m1.m2/r^2)

F = 6.67 *n10^11 (1000 * 1000/ 0.5 * 0.5)

F = 2. 67 * 10^-4 N

Explanation

Lipids are an umbrella term for Triglycerides, Phospholipids and Sterol.

Explanation

Propranolol is a non-selective beta-blocker that blocks both beta-1 and beta-2 receptors.

Therapeutic uses:

Used to treat conditions like hypertension, angina pectoris, arrhythmias, migraines, and hyperthyroidism. 

Side effects:

Due to its non-selective nature, potential side effects can include bronchospasm in individuals with asthma, fatigue, and cold extremities. 

Explanation

A) Methane (CH₄) - Molecular weight = 16 g/mol
B) Ethane (C₂H₆) - Molecular weight = 30 g/mol
C) Propane (C₃H₈) - Molecular weight = 44 g/mol
D) Butane (C₄H₁₀) - Molecular weight = 58 g/mol

Correct Answer: D) Butane

Butane is the heaviest among the options listed, with a molecular weight of 58 g/mol.

Explanation

An indehiscent integument megasporangium in the form of ovule is found in spermatophytes.

The ovule then forms the seed after fertilization

Explanation

In sociology, a community is defined as a collection of people who adhere to a social structure within a society.

Sociology means انسانی معاشرے کی تحقیق و ترقی پر مبنی علم

Community means سماج, معاشرہ, فرقہ, برادری

Explanation

A well-accepted example of pleomorphism is Helicobacter pylori, which exists as both a helix-shaped form (classified as a curved rod) and a coccoid form.

H. pylori is a type of bacteria that infects your stomach the first part of your small intestine (the duodenum).

This can cause redness and soreness (inflammation)

Explanation

Parvoviruses are single-stranded DNA viruses that have a predilection for mitotically active host cells.

Parvoviruses that infect rats include (Kilham's) rat virus (RV), (Toolan's) H-1 virus, rat parvovirus (RPV), and rat minute virus (RMV).

Explanation

Uranium is the most widely used fuel by nuclear power plants for nuclear fission.

Nuclear power plants use a certain type of uranium—U-235—as fuel

because its atoms are easily split apart.
