Life science review

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Glucose is essential for cellular respiration as it is the primary fuel that cells use to produce energy.

An organism is a living entity that can grow and reproduce, while a virus is a non-living entity that requires a host cell to replicate.

A parasite is an organism that lives on or in a host organism and benefits at the host's expense.

Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes and results in offspring that are genetically identical to the parent.

Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent nucleus.

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

The respiratory and circulatory systems are primarily involved in gas exchange, taking in oxygen and expelling carbon dioxide.

A mass extinction event leads to the rapid loss of a large number of species, disrupting ecosystems and altering the course of evolution.
