Front

What is facilitated diffusion?

Back

Facilitated diffusion is a passive transport process that involves the use of carrier proteins or channels to help move substances across a cell membrane without the use of ATP.

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, unicellular organisms that lack a membrane-bound nucleus and membrane-bound organelles.

Front

What determines a person's blood type?

Back

A person's blood type is determined by the presence or absence of specific antigens on the surface of red blood cells.

Front

What occurs during crossing over in meiosis?

Back

During crossing over in meiosis, there is an exchange of genetic material between homologous chromosomes, leading to genetic variation.

Front

What type of graph is most suitable for displaying parts of a whole?

Back

A pie chart is most suitable for displaying parts of a whole, as it visually represents the proportion of each part relative to the total.

Front

What is active transport?

Back

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

Front

What are the main differences between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

Front

What is the role of carrier proteins in facilitated diffusion?

Back

Carrier proteins assist in the transport of specific molecules across the cell membrane by changing shape to allow the molecule to pass.

Front

What is the significance of crossing over in genetics?

Back

Crossing over increases genetic diversity by allowing the exchange of genetic material between homologous chromosomes during meiosis.

Front

What are antigens?

Back

Antigens are molecules or structures that are recognized by the immune system, often found on the surface of cells, including red blood cells.
