Explanation

• Bile salts are produced by the liver and stored in the gallbladder.
• They are released into the duodenum (the first part of the small intestine) to facilitate fat digestion.

Explanation

• The energy released (14135 KJ) is equivalent to the energy released from the oxidation of glucose (C6H12O6), which is typically around 2820 KJ/mol.
• To find the number of moles of glucose consumed, you can divide the energy released (14135 KJ) by the energy released per mole of glucose (2820 KJ/mol):
• 14135 KJ ÷ 2820 KJ/mol = 5 mol

Explanation

Food chains are linear sequences showing the feeding relationships between organisms in an ecosystem.

They illustrate how energy and nutrients are passed from one organism to another, from producers (like plants) to consumers (like animals).

Explanation

During metaphase, homologous chromosomes (pairs of chromosomes that contain the same genes) arrange themselves on the equator of the spindle, also known as the metaphase plate.

This is a critical step in the cell division process, ensuring that each daughter cell receives a complete set of chromosomes.

Explanation

Chromosomes are thread-like structures that appear during cell division, specifically during the prophase stage of mitosis or meiosis.

They are made up of condensed chromatin and carry genetic information from one generation of cells to the next.

Explanation

Biodiversity refers to the degree of variation within or among species.

Including genetic, species, and ecosystem diversity, across different regions of the Earth.

Explanation

Bu Ali Sina (Avicenna), a renowned Persian physician and polymath, identified various diseases, including tuberculosis and meningitis.

In his seminal work "The Canon of Medicine".

Explanation

The first scientist who gave the concept of gravitation was Sir Isaac Newton.

He published his groundbreaking work, "Universal Law of Gravitation," in 1687.

It explained how gravity works and how it affects objects on Earth and in the universe.

Explanation

A tightrope walker carries a long pole to lower their center of gravity, making it easier to balance and maintain equilibrium.

By spreading their weight over a larger area (including the pole), they reduce the risk of toppling over.

Explanation

• A solution that contains a solid solute dissolved in a liquid solvent is called a solid-in-liquid solution or a solute-solvent solution.
• This is the most common type of solution, where a solid substance (the solute) is dissolved in a liquid substance (the solvent).
