Front

What is exponential growth in biology?

Back

Exponential growth refers to a population growth pattern where the number of individuals increases at a constant rate over time, leading to a rapid increase in population size.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature for enzyme activity is the temperature at which an enzyme functions most efficiently, often resulting in the highest reaction rate. For example, some enzymes work best at 30°C.

Front

What do prokaryotic and eukaryotic cells have in common?

Back

Both prokaryotic and eukaryotic cells contain DNA, which carries genetic information.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they are responsible for producing energy through cellular respiration.

Front

What is the probability of a child having freckles if both parents are heterozygous?

Back

If both parents are heterozygous for freckles (Ff), there is a 75% probability that their child will have freckles.

Front

Define logistic growth in population ecology.

Back

Logistic growth is a population growth model that describes how a population grows rapidly at first and then slows as it approaches the carrying capacity of its environment.

Front

What is the function of enzymes in biological reactions?

Back

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

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is the significance of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
