Explanation

Acids are known to cause corrosive effects on skin, including burns, ulcers, and damage to skin tissue.

Examples of corrosive acids include sulfuric acid (H2SO4), hydrochloric acid (HCl), and nitric acid (HNO3).

Explanation

Hallucinogens are drugs that alter perception, thought, and mood, often causing:

• Blurred vision
• Hallucinations (seeing or hearing things that aren't there, like unseen faces)
• Altered mood, including euphoria

Explanation

Competition is the interaction between organisms of a community that occupy the same habitat and seek the same resources, such as food, water, light, and space.

This "cold war" leads to a struggle for existence, where individuals with favorable traits are more likely to survive and reproduce.

Explanation

The biosphere is the global sum of all ecosystems on Earth, encompassing everything from the tiniest microbe to the mightiest tree.

It's the zone of life on our planet, where all living things exist and interact.

The biosphere includes land, oceans, atmosphere, and even the depths of the Earth's crust.

Explanation

In an optical fiber, the core is made of a material with a relatively high refractive index, typically glass or plastic with a high refractive index.

This allows the light to be confined and transmitted through the fiber via total internal reflection.

The cladding surrounding the core has a lower refractive index, which helps to keep the light within the core.

Explanation

The ozone layer is a region within the stratosphere, extending from about 15 to 30 km (9 to 19 miles) above the Earth's surface.

It contains a high concentration of ozone (O3), a molecule made up of three oxygen atoms. 

The ozone layer plays a crucial role in protecting the Earth from harmful ultraviolet (UV) radiation from the sun, particularly UV-C and UV-B rays.

Explanation

• An ecosystem is a specific area where living organisms (the community) interact with each other and their non-living environment (such as water, air, soil, sunlight, and temperature).
• It's a self-contained system where living and non-living components work together to create a functional unit.

Explanation

Suckers are shoots that arise from buds on the base of a parent plant, often at the soil line or just below.

They are a type of vegetative propagation, allowing the plant to produce new stems and roots.

Suckers can grow into new individuals, eventually forming a clump or colony.

Explanation

The cerebellum is responsible for:

• Coordinating movements
• Maintaining posture and balance
• Regulating muscle tone
• Learning new motor skills
• Precision and accuracy in movements

Explanation

If the direction of the magnetic field is reversed, the direction of the force exerted on a charged particle or a current-carrying wire will also be reversed.

This is because the force due to a magnetic field depends on the direction of the field.

The direction of the current or velocity, and the charge of the particle (if applicable).
