Front

What is natural selection?

Back

Natural selection is the process by which organisms that are best adapted to their environment survive and reproduce, leading to an increase in the frequency of their genes in the population.

Front

How does natural selection improve a population?

Back

The individual organisms that are best adapted to the current environment survive, and their gene types increase in the population.

Front

Which species’ DNA is most similar to the DNA of the toothed whale?

Back

The DNA of the Baleen Whale is most similar to that of the toothed whale.

Front

How many alleles does an offspring receive from EACH parent for a specific trait?

Back

An offspring receives one allele from each parent for a specific trait.

Front

What is active transport in cells?

Back

Active transport is the movement of materials into or out of a cell that requires energy.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the need for energy, typically along a concentration gradient.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What are the components of a nucleotide?

Back

A nucleotide is composed of a phosphate group, a sugar, and a nitrogenous base.

Front

What is the role of alleles in genetics?

Back

Alleles are different versions of a gene that determine specific traits in an organism.
