Explanation

Enzymes act as biological catalysts, speeding up chemical reactions in the body without being consumed in the process.

They are essential for various physiological processes, including digestion and metabolism.

Explanation

Controlling diabetes often involves:

• reducing carbohydrate intake to manage blood sugar levels 
• increasing intake of healthy fats to provide sustained energy and support overall health.

This approach stabilizes blood glucose levels while promoting a balanced and nutritious diet.

Explanation

Explanation

Ribosomes are tiny organelles found in both prokaryotic and eukaryotic cells.

They are responsible for synthesizing proteins by linking amino acids according to genetic instructions.

Explanation

The ovary is the female reproductive part of a flower that holds and protects ovules (which develop into seeds after fertilization).

It is part of the pistil (gynoecium) and matures into a fruit after pollination.

Explanation

An allele that masks the expression of another allele is called a dominant allele.

Organisms in different genera generally cannot produce fertile offspring.

Explanation

Meiosis is a type of cell division that reduces the chromosome number by half and is essential for the formation of germ cells (sperm and egg).

It ensures genetic diversity.

It is fundamental to sexual reproduction.

Explanation

Friendly bacteria in our large intestine produce Vitamin K, which helps in blood clotting.

These bacteria mainly synthesize Vitamin K2, important for bone and heart health.

Explanation

Echinoderms (such as starfish, sea urchins, and sea cucumbers) are invertebrates because they lack a backbone.

They have a unique water vascular system and radial symmetry.
