Explanation

The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter

. Sometimes an earthquake has foreshocks.

Explanation

The central atom of hemoglobin is iron, which binds to oxygen in the blood.

Hemoglobin is a protein in red blood cells responsible for transporting oxygen from the lungs to the rest of the body.

Explanation

When cyclohexane is oxidized with nitric acid (HNO₃), it typically yields adipic acid.

Adipic acid is a dicarboxylic acid with the formula C₆H₁₀O₄, and it is commonly used in the production of nylon. 

Explanation

Ferromagnetic materials are those that can be magnetized and retain their magnetization even after the external magnetic field is removed.

These materials have a high magnetic permeability and strong interactions between magnetic moments, which align in the same direction.

Explanation

This is done through an electrophilic attack on the aromatic ring with the help of a carbonation.

The Friedel-Crafts alkylation reaction is a method of generating alkylbenzenes by using alkyl halides as reactants.

The Friedel-Crafts alkylation reaction of benzene is illustrated below.

Explanation

Inflorescence: raceme-like. Flower: calyx 2--3 mm; corolla 10 mm wide,

white, lobes deep; anthers 1.4--2.2 mm; style 3--5 mm. Fruit: 6--8 mm, black. Seed: 1.5--2.5 mm.

Explanation

Neural cells originate from the ectoderm layer of the embryo during early development.

As these cells differentiate, they give rise to various types of cells within the nervous system, including neurons (nerve cells) and glial cells (supporting cells). 

Explanation

Carbon dioxide (CO₂) is the gas commonly used in carbonated beverages.

It dissolves in the liquid under pressure, creating the fizzy bubbles that are characteristic of drinks like:

• soda
• sparkling water
• beer
