Explanation

Isotopes of an element have the same number of protons.

Explanation

Bees must collect nectar from approximately 20 MILLION flowers to make 1 pound of honeycomb.

Explanation

Changes in pH can cause enzymes to denature, losing their native structure and activity.

This is because enzymes are highly specific to their optimal pH range.

Changes in pH can disrupt the delicate balance of charges and hydrogen bonds that maintain the enzyme's active structure.

Explanation

As temperature increases, the rate of reaction initially increases due to the increased kinetic energy of the molecules.

It allowing them to overcome the activation energy barrier and react more quickly.

Explanation

Endangered species are animals, plants, or fungi that are at risk of becoming extinct in the near future.

They are threatened by various factors, such as habitat loss, pollution, climate change, overhunting, and human activities.

Explanation

Scientific names of organisms, also known as binomial nomenclature, should be printed in italics.

This is a universal convention in scientific writing to distinguish the scientific name from the rest of the text.

Explanation

• A magnifying glass, also known as a convex lens.
• It forms an enlarged virtual image that is upright.

The image formed by a magnifying glass:

• Image type: Virtual

Explanation

A peptide is a molecule composed of two or more amino acids linked together through amide bonds.

It is a polyamide, meaning it is a polymer of amino acids.

Peptides are smaller than proteins, which are long chains of amino acids.

Explanation

The Human Genome Project (HGP) was a global research effort that successfully mapped the entire human genome, identifying all its genes and their sequences.

The project was completed in 2003.

It's findings have revolutionized our understanding of human biology, disease, and treatment.

Explanation

The frontal lobe, particularly the prefrontal cortex.

It is responsible for higher-order cognitive functions such as:

• Reasoning
• Problem-solving
• Decision-making
• Logical thinking
• Planning
