Explanation

 Proteins are indeed large molecules that cannot pass through the pores of a dialysis membrane due to their size,

Allowing dialysis to be used for purification or buffer exchange by separating them from smaller molecules and ions. 

Explanation

A gas behaves non-ideally at low temperature and high pressure. 

At low temperatures, molecules have less kinetic energy,

Meaning they move more slowly and are more likely to experience intermolecular forces, which causes them to deviate from ideal behavior. High pressure also contributes to non-ideal behavior because the molecules are closer together, leading to increased interactions. 

Explanation

Molting (also spelled moulting) is the process by which insects shed their exoskeleton to grow.

This process:

Occurs only during the immature stages (larva or nymph).

Stops once the insect becomes an adult (mature) — the adult stage does not molt.

Explanation

 In a vertebrate, a reflex action is induced by a sensory nerve. 

A sensory nerve detects the stimulus, which triggers the signal to the spinal cord, leading to the motor neuron response in a reflex action. 

Explanation

The hormone that stimulates the mammary glands to enlarge at puberty is estrogen. 

During puberty, rising levels of estrogen in girls trigger the development of breast tissue by promoting the growth of the ductal system and the accumulation of fat tissue. 

Explanation

An alkyl group is formed by removing a hydrogen atom from an alkane, and since the hydrogen atom is removed with one bonding electron, the resulting group has an unpaired electron, making it a radical. 

Explanation

 According to Gauss's Law, the net electric flux through a closed surface depends on the net charge enclosed.

If equal and opposite charges are present inside the surface, their total is zero, so the net electric flux is also zero.

Explanation

The kinetic energy is mathematically expressed as K. E=12mv2,

where m is the mass of the body and v is the velocity with which the body is moving

If velocity v is doubled, the kinetic energy becomes four times as kinetic energy is directly proportional to the square of velocity.

Explanation

Ripened ovary or fertilized ovary is called a fruit.

Post-fertilization changes in plants involve:

endosperm formation

embryo development

seed

fruit formation.

while

Ovules at maturity or ripened ovules are known as seeds.

The second male gamete fuses with the diploid secondary nucleus to form triploid endosperm which nourishes the developing embryo.

Explanation

A tonne (also called metric ton) is a non-SI unit of mass defined as 1 tonne= 1000 kg (= 106 g).

A tonne is a metric unit of mass equivalent to 1,000 kg or 2,204.6 lbs.

while

ton is an imperial unit of mass equivalent to 1,016.047 kg or 2,240 lbs.
