What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions, such as temperature and blood glucose levels.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for assembling amino acids into proteins.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, essential for growth and repair in multicellular organisms.

Front

What happens during prophase in mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What is the significance of the triplet code in DNA?

Back

The triplet code in DNA consists of three nucleotide bases that correspond to a specific amino acid, determining the sequence of amino acids in a protein.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen and produces less energy.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment in plants that absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen.
