Explanation

• Dispersion is the optical phenomenon where white light is split into its constituent colors, also known as a spectrum.
• This occurs when light passes through a medium with a refractive index that varies with wavelength, such as a prism.

The process of dispersion involves two stages:

1. Refraction (bending of light)
2. Separation of colors (splitting into distinct colors)

The seven distinct colors that make up the visible spectrum, in order, are:

1. Red
2. Orange
3. Yellow
4. Green
5. Blue
6. Indigo
7. Violet

Explanation

Water is neutral and does not have a taste.

The taste buds on our tongues can detect five basic tastes: sweet, sour, salty, bitter, and umami (savory).

Water does not contain any molecules that stimulate these taste buds, making it tasteless.

Explanation

Biotechnology in industry refers to the use of biological systems, living organisms, or derivatives thereof, to develop new products and processes on a large scale.

This includes the production of alcohol, antibiotics, vaccines, biofuels, and other commodities.

Explanation

Air pollution refers to the presence of harmful substances in the air, including solid waste and excess gases, which can harm human health and the environment.

Examples include particulate matter, carbon monoxide, and volatile organic compounds, which can lead to respiratory problems and other health issues.

Explanation

The female gametophyte of angiospermic plants is the embryo sac.

It ilso known as the megagametophyte.

It is the haploid (containing one set of chromosomes) structure within the ovule that contains the egg cell and is responsible for fertilization.

Explanation

Homeostasis is the set of metabolic reactions that maintain the internal environment of an organism, regulating factors.

Such as temperature, pH, blood sugar levels, and blood pressure.

Explanation

The gravitational force between two objects is independent of the medium between them.

Gravity acts through a vacuum just as it does through a medium like air, water, or solid objects.

The presence or absence of a medium does not affect the gravitational force between the objects.

Explanation

The weight of a body is the force exerted on it by gravity.

It depends on the gravitational pull of the planet or moon it is on.

Since the gravitational pull varies from place to place (it is stronger near the surface of the Earth than on a mountain, and weaker on the Moon than on the Earth), the weight of a body also varies.

Explanation

• The light-dependent reactions (also known as the Hill reaction) occur in the thylakoid membranes of the chloroplast.
• Thylakoids are specialized membranous structures found in chloroplasts, where light energy is absorbed and converted into ATP and NADPH.

Explanation

 The full form of RDX is Royal Demolition Explosive.

It was first reported in 1898 by Georg Friedrich Henning

who obtained a German patent for its manufacturing by nitrolysis or hexamine.

It is also known as cyclonite or hexogen.

The chemical name for RDX is 1,3,5-trinitro-1,3,5-triazine.
