Thermal Homeostasis and Adaptations

Front

What is thermal homeostasis?

Back

Thermal homeostasis is the process by which an organism maintains its internal body temperature within a certain range, despite external temperature changes.

Front

What are adaptations in the context of thermal homeostasis?

Back

Adaptations are traits or characteristics that enhance an organism's ability to survive and reproduce in its environment, particularly in relation to temperature regulation.

How do ectothermic animals regulate their body temperature?

Back

Ectothermic animals, or 'cold-blooded' animals, rely on external environmental conditions to regulate their body temperature, often basking in the sun or seeking shade.

Front

What is the role of genes in cell differentiation?

Back

Genes provide the instructions for cells to develop into specialized types, allowing them to perform specific functions within an organism.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein or set of proteins.

Front

How many chromosomes do fruit flies have in their somatic cells?

Back

Fruit flies have 8 chromosomes in their somatic cells.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of gametes (sperm and eggs).

Front

What is the significance of genetic mutations in adaptation?

Back

Genetic mutations can lead to variations that may provide advantages in survival and reproduction, allowing species to adapt to changing environments.

Front

What is the difference between ectothermic and endothermic animals?

Back

Ectothermic animals rely on external heat sources to regulate their body temperature, while endothermic animals generate heat internally to maintain a stable body temperature.

Front

What is the function of proteins in living organisms?

Back

Proteins perform a wide range of functions, including acting as enzymes, structural components, and signaling molecules.
