Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special proteins, without the use of energy.

Front

What type of cells does meiosis produce?

Back

Meiosis produces haploid cells, which have half the number of chromosomes compared to diploid cells.

Front

What is the diploid number of chromosomes in a dog?

Back

The diploid number of chromosomes in a dog is 78.

Front

What does exponential growth in a population graph indicate?

Back

Exponential growth indicates that a population is increasing rapidly without any limiting factors.

Front

What is carrying capacity in an ecosystem?

Back

Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely without being degraded.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells contain one set of chromosomes (n), while diploid cells contain two sets of chromosomes (2n).

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first and then levels off as it reaches the carrying capacity.

Front

What is emigration in population dynamics?

Back

Emigration is the movement of individuals out of a population, which can decrease the population size.
