The process that moves any material from high concentrations to low concentrations is called ____.
-
Diffusion
-
Active transport
-
Endocytosis
-
Osmosis
Correct Answer
A. DiffusionExplanation
Diffusion is the process that moves any material from high concentrations to low concentrations. It occurs due to the random movement of molecules or particles. In this process, substances move down their concentration gradient until equilibrium is reached. Diffusion is a passive process that does not require any energy input. Active transport, endocytosis, and osmosis are different processes that involve the movement of substances but they are not specifically related to the movement from high to low concentrations.Rate this question:

The process in which liquids from the surrounding area are taken into the cell is called ____.
-
Phagocytosis
-
Pinocytosis
-
Exocytosis
-
Passive transport
Correct Answer
A. PinocytosisExplanation
Pinocytosis is the process in which liquids from the surrounding area are taken into the cell. It involves the formation of small vesicles that engulf the extracellular fluid containing dissolved substances. This process is a form of endocytosis, where the cell membrane invaginates and forms a vesicle to bring the extracellular fluid into the cell. Unlike phagocytosis, which involves the engulfment of solid particles, pinocytosis specifically refers to the uptake of liquids. Exocytosis, on the other hand, is the process by which substances are released from the cell. Passive transport refers to the movement of substances across the cell membrane without the use of energy.Rate this question:

-
Formation of power
-
Chemical reactions
-
Ability to do work
-
Creation of heat
Correct Answer
A. Ability to do workExplanation
Energy can be defined as the ability to do work. Work refers to the transfer of energy from one object to another, or the transformation of energy from one form to another. Energy allows objects to exert a force and cause a displacement, thereby performing work. This definition encompasses various forms of energy, including mechanical, electrical, thermal, and potential energy. It highlights the fundamental concept that energy enables the accomplishment of tasks or the production of a change in the physical state of a system.Rate this question:

A solution that has a greater concentration than a cell, it would be a ____ solution.
-
Hypertonic
-
Hypotonic
-
Isotonic
-
Heterogeneous
Correct Answer
A. HypertonicExplanation
A solution that has a greater concentration than a cell is called a hypertonic solution. In a hypertonic solution, the concentration of solutes is higher outside the cell compared to the inside. As a result, water molecules tend to move out of the cell through osmosis, causing the cell to shrink or shrink.Rate this question:

What does this image represent?
-
Passive transport
-
Active transport
-
Pinocytosis
-
Phagocytosis
Correct Answer
A. Active transportExplanation
This image represents active transport because active transport is the movement of molecules across a cell membrane against the concentration gradient, requiring the use of energy. The image likely shows molecules being actively transported from an area of low concentration to an area of high concentration, which requires the expenditure of energy by the cell.Rate this question:

What process is shown in this picture? (The blue and purple blobs are transport proteins and the green pieces are solutes.)
-
Active transport
-
Facilitated diffusion
-
Osmosis
-
Pinocytosis
Correct Answer
A. Facilitated diffusionExplanation
The process shown in the picture is facilitated diffusion. This is indicated by the presence of transport proteins (blue and purple blobs) that aid in the movement of solutes (green pieces) across the cell membrane. Facilitated diffusion is a passive process that does not require energy and relies on the assistance of specific proteins to transport molecules across the membrane from an area of high concentration to an area of low concentration.Rate this question:

Which of these organisms has the largest surface area to volume ratio?
-
Bacterium
-
Butterfly
-
Bacteria
-
Elephant
Correct Answer
A. BacteriumExplanation
Bacterium has the largest surface area to volume ratio among the given options. This is because bacteria are unicellular organisms with a high surface area relative to their volume. Their small size allows for a larger surface area compared to their internal volume, which is important for efficient nutrient exchange and waste removal. In contrast, the butterfly, elephant, and bacteria are multicellular organisms with larger volumes and relatively smaller surface areas.Rate this question:

What happens to red blood cells if we place them in water?
-
They remain unchanged
-
They swell up and burst
-
They start shriveling as water is lost by osmosis
-
They get shrink
Correct Answer
A. They swell up and burstExplanation
When red blood cells are placed in water, they undergo a process called hemolysis. This occurs because water enters the cells through osmosis, causing them to swell up and eventually burst. The red blood cells have a higher concentration of solutes compared to the water, so water molecules move into the cells to equalize the concentration. As a result, the cells become swollen and eventually rupture, leading to the release of their contents.Rate this question:

The purpose of cholesterol in the cell membrane is ____________.
-
Maintain fluidity
-
Communicate with other cells
-
Help cells stick together
-
Make the bilayer hydrophobic
Correct Answer
A. Maintain fluidityExplanation
Cholesterol plays a crucial role in maintaining the fluidity of the cell membrane. It helps regulate the movement of molecules across the membrane by preventing it from becoming too rigid or too fluid. By inserting itself between the phospholipids in the bilayer, cholesterol acts as a buffer, reducing membrane permeability to small molecules while still allowing for the necessary flexibility for cell function. This ensures that the cell membrane maintains its integrity and functionality, allowing for proper cellular processes to occur.Rate this question:

What are the 2 types of cell transport? (Select the options)
-
Active
-
Passive
-
Diffusion
-
Infusion
Correct Answer(s)
A. Active
A. PassiveExplanation
The two types of cell transport are active and passive. Active transport requires the cell to expend energy in order to move molecules or ions across the cell membrane against their concentration gradient. Passive transport, on the other hand, does not require energy and occurs naturally, allowing molecules to move from an area of high concentration to an area of low concentration. Diffusion is an example of passive transport, while infusion is not a type of cell transport.Rate this question:
