Explanation

In the ball and bowl system, the mean position (also known as the equilibrium position) is at the center of the bowl.

This is the position where the ball comes to rest when it is not disturbed.

Explanation

Amino acids are the building blocks of proteins, which are long chains of amino acids linked together by peptide bonds.

There are 20 different amino acids that the human body uses to build proteins.

They are essential for various cellular processes, including structure, function, and regulation.

Explanation

Glucose (C6H12O6) is a type of carbohydrate, specifically a simple sugar or monosaccharide.

It is a vital source of energy for many living organisms, including humans.

Glucose is a primary component of many carbohydrates, such as starch, cellulose, and glycogen.

Explanation

Homozygous refers to the state where an individual inherits two identical copies of a gene (one from each parent) that code for the same trait or characteristic.

Explanation

The larynx (voice box) is located on top of the trachea (windpipe), which is a tube that leads to the lungs.

The larynx sits at the junction of the pharynx (throat) and the trachea, and it plays a crucial role in speech and breathing.

Explanation

Rockets are used to put satellites into orbit around the Earth.

Rockets provide the necessary thrust and velocity to overcome the Earth's gravitational pull and reach the desired altitude and orbit.

Explanation

• Optimum pH is the point where an enzyme is most active.
• It is the pH at which the enzyme catalyzes the reaction at its maximum rate. 
• Different enzymes have different optimum pH values, depending on their structure and function.

Explanation

• In metaphase, the chromosomes (now consisting of two sister chromatids each) align themselves at the center of the cell, attached to the microtubules of the mitotic spindle.
• This forms the metaphase plate, where each chromosome is positioned at the equator of the cell, ready for separation.

Explanation

Biodiversity is impacted by various human activities, including:

• Pollution: Chemical pollutants can alter ecosystems, affecting species development, growth, and survival.
• Deforestation: Habitat destruction and fragmentation lead to population decline, isolation, and extinction.
• Overhunting: Overexploitation of species for food, trophies, or other purposes can deplete populations and drive extinctions.

Explanation

The physical weight of our body is determined by the pull of gravity on it
