Explanation

 Pyramidal molecular structure is typically found in molecules like ammonia (NH₃), where there is a central atom with lone pairs and three bonded atoms.

Explanation

Sickle cell anemia is caused by a mutation in the gene that codes for the beta-globin chain of hemoglobin,

where valine is substituted for glutamic acid at the sixth position, causing the red blood cells to assume a sickle shape.

Explanation

The presence of a dielectric material between the plates of a capacitor reduces the electric field by a factor called the dielectric constant 𝐾

The electric field E in a capacitor with a dielectric is related to the field E0 without the dielectric by:

E= E0/K

​When the dielectric material is removed, the dielectric constant K becomes 1 (for vacuum or air), and the electric field reverts to its original strength, increasing by a factor of 𝐾

Thus, when the dielectric is removed, the electric field increases.

Explanation

The temperature within 10 km of the Earth's core is approximately 4000 Kelvin (K).

At such depths, the temperature is incredibly high due to the immense pressure and heat generated by the Earth's core.

Explanation

The hydrolysis of fats is brought about by lipase enzymes.

Lipases are a class of enzymes that catalyze the hydrolysis of fats into fatty acids and glycerol.

Explanation

Science is the systematic study of the nature and behavior of the material and physical universe, based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms.

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

Electricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber.
