• Passive immunity

• Active immunity

• Innate immunity

• Adaptive immunity

Answer explanation

The form of immunity provided by the immune response of the body upon detection of a pathogen is Active immunity.

What is the method of cell division used by prokaryotes involving replication of the circular DNA and plasmids followed by cytoplasmic division?

• Mitosis

• Meiosis

• Binary fission

• Budding

Answer explanation

Binary fission is the method of cell division used by prokaryotes involving replication of circular DNA and plasmids followed by cytoplasmic division.

What is a phospholipid bilayer studded with proteins that surrounds cells and separates them from their environment called?

• Cell wall

• Cell membrane

• Cell vacuole

• Cytoplasm

Answer explanation

The phospholipid bilayer studded with proteins that surrounds cells and separates them from their environment is called the cell membrane.

Florence and Oliver are studying how cells transport substances. What is a method of membrane transport where two substances are both transported across a membrane at the same time either in the same direction or opposite directions called?

• Active transport

• Passive transport

• Co-transport

• Diffusion

Answer explanation

Co-transport is the method of membrane transport where two substances are both transported across a membrane at the same time either in the same direction or opposite directions.

In a biology class, Florence and Alexander are observing cell division under a microscope. What is the division of the cytoplasm to produce two new cells called?

Answer explanation

The division of the cytoplasm to produce two new cells is called cytokinesis.

During a biology experiment, Anaya observed the passive movement of substances from a high concentration to a lower concentration through transport proteins without the use of energy. What is this process called?

• Active transport

• Facilitated diffusion

• Osmosis

• Endocytosis

Answer explanation

The passive movement of substances from a high concentration to a lower concentration through transport proteins without the use of energy is called facilitated diffusion.

What is the whip-like structure found on bacterial cells that is used for cell movement?

• Cilia

• Pseudopodia

• Flagella

• Microvilli

Answer explanation

The whip-like structure found on bacterial cells used for cell movement is called Flagella.

Which organelle is involved in the modification and packaging of proteins in eukaryotic cells?

• Ribosome

• Golgi apparatus

• Endoplasmic reticulum

• Lysosome

Answer explanation

The Golgi apparatus is involved in the modification and packaging of proteins in eukaryotic cells.

What type of T cell in the immune system stimulates cytotoxic T cells, B cells, and phagocytes?

• Suppressor T cell

• Helper T cell

• Memory T cell

• Cytotoxic T cell

Answer explanation

Helper T cells stimulate cytotoxic T cells, B cells, and phagocytes in the immune system, aiding in the immune response against pathogens.

• Chloroplast

• Mitochondrion

• Nucleus

• Ribosome

Answer explanation

The organelle in eukaryotic cells that is the site of aerobic respiration is the mitochondrion.
