Explanation

• The odd one out is Active transport.
• Active transport requires energy (ATP) to move substances against their concentration gradient.
• Whereas diffusion, facilitated diffusion and osmosis are passive processes.

Explanation

• The rough endoplasmic reticulum (RER) is responsible for synthesizing proteins, which are then transported to other parts of the cell or secreted outside.
• The RER has ribosomes attached to its surface, where protein synthesis occurs.

Explanation

Photosynthesis splits water molecules (H2O) into oxygen (O2) and hydrogen ions (H+), releasing oxygen as a byproduct.

This process is essential for life on Earth, as it provides the oxygen that supports aerobic respiration in most living organisms.

Explanation

• The period of rapid growth and development is called adolescence.
• This stage typically involves significant physical, emotional, and cognitive changes as individuals transition from childhood to adulthood.

Explanation

• Organic solvents are not a typical factor that affects enzyme activity.
• In fact, many enzymes are denatured or inactivated in the presence of organic solvents.
• As they can disrupt the enzyme's native structure and function.

Explanation

• In Anaphase-II of meiosis, the centromeres shorten and the paired chromatids (sister chromatids) are pulled away from one another, moving to opposite poles of the cell.
• This is the stage where the genetic material is finally separated, and each pole receives a complete set of chromosomes.

Explanation

Deforestation is the permanent removal of forests, usually as a result of human activities like logging, agriculture, urbanization, and mining.

It leads to the loss of habitats, biodiversity, and ecosystem services, as well as contributing to climate change.

Explanation

Biogeography is the study of the distribution of living organisms across different regions of the world.

Including the factors that influence their distribution.

Such as geography, climate, geology, and evolutionary history.

Explanation

Vitamin A is essential for the production of rhodopsin, the visual pigment in the retina that allows us to see in low light conditions.

Explanation

• Enzymes are biological molecules made up of proteins, which catalyze chemical reactions, speeding up metabolic processes in living organisms.
• Proteins provide the structure and active site for enzymes to bind substrates and facilitate chemical reactions.
