Semester 1 Biology Final Review

Front

What are the processes involved in the carbon cycle?

Back

Photosynthesis, Respiration, Decomposition, Fossil fuel combustion.

Front

How do you calculate the change in population size?

Back

(Births + Immigration) - (Deaths + Emigration).

Front

What is a density dependent limiting factor?

Back

A factor that affects population size based on the population density, such as competition, disease, and predation.

Front

What do epithelial cells form together?

Back

A single tissue layer.

Front

Which macromolecule is the major component of cell membranes?

Back

Lipids.

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is respiration in biological terms?

Back

The process of breaking down glucose to release energy, typically involving oxygen.

Front

What role does decomposition play in the ecosystem?

Back

Decomposition breaks down dead organic matter, recycling nutrients back into the soil.

Front

What is the difference between immigration and emigration?

Back

Immigration is the arrival of individuals into a population, while emigration is the departure of individuals from a population.

Front

What is a macromolecule?

Back

A large molecule composed of thousands of atoms, such as proteins, lipids, carbohydrates, and nucleic acids.
