- A.
A cell which has a specific function to perform
- B.
The basic unit of all madder
- C.
An organism which is made of one cell
Correct Answer
C. An organism which is made of one cellExplanation
Unicellular refers to an organism that is made up of only one cell. Unlike multicellular organisms, which are composed of multiple cells with specialized functions, unicellular organisms are capable of performing all necessary functions within a single cell. This includes processes such as reproduction, metabolism, and responding to their environment. Examples of unicellular organisms include bacteria, protozoa, and certain types of algae.Rate this question:

what is Multicellular?
- A.
A group of tissues
- B.
Anything which can independently carry out life processes
- C.
An organism which is made of more than one cell
Correct Answer
C. An organism which is made of more than one cellExplanation
Multicellular refers to an organism that is made up of more than one cell. This means that the organism's body is composed of multiple cells that work together to perform various functions. Unlike unicellular organisms, which consist of only one cell, multicellular organisms have specialized cells that are organized into tissues, organs, and organ systems. This organization allows multicellular organisms to carry out complex life processes and perform specific functions efficiently.Rate this question:

Cell membrane is?
- A.
Flexible structure which surrounds a cell and controls the movement of materials in and out of the cell
- B.
Protein which requires energy
- C.
A cell group of cells
Correct Answer
A. Flexible structure which surrounds a cell and controls the movement of materials in and out of the cellExplanation
The cell membrane is a flexible structure that surrounds a cell and regulates the movement of substances in and out of the cell. It acts as a protective barrier, allowing certain molecules to pass through while preventing others from entering or leaving. This selective permeability is essential for maintaining the cell's internal environment and ensuring proper functioning.Rate this question:

Phospholipids is a type of molecule which regulates the transport of materials?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Phospholipids are indeed a type of molecule that regulates the transport of materials. They are a major component of cell membranes and play a crucial role in maintaining the integrity and functionality of cells. The structure of phospholipids allows them to form a lipid bilayer, which acts as a barrier and selectively controls the movement of substances in and out of the cell. This regulation of transport is essential for various cellular processes, such as nutrient uptake, waste removal, and cell signaling. Therefore, the statement is true.Rate this question:

Proteins are one type of biochemical which regulates the transport of materials?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Proteins are indeed one type of biochemical that play a crucial role in regulating the transport of materials within cells. They can act as transporters, channels, or carriers, facilitating the movement of ions, molecules, and other substances across cell membranes. Additionally, proteins are involved in intracellular transport processes, such as the movement of vesicles or organelles within the cell. Therefore, the statement that proteins regulate the transport of materials is true.Rate this question:

what is Specialized cell?
- A.
A group of organs
- B.
A group of cells
- C.
A cell which has a specific function to perform
Correct Answer
C. A cell which has a specific function to performExplanation
A specialized cell refers to a cell that has a specific function to perform. Unlike other cells, which are more general in nature, specialized cells are uniquely structured and equipped to carry out specific tasks within an organism. These cells have distinct features and characteristics that allow them to perform their designated functions efficiently. Specialized cells are found in various tissues and organs throughout the body, contributing to the overall functioning and organization of the organism.Rate this question:

Active transport is?
- A.
The movement of particles through a protein which requires energy
- B.
The movement of particles through a protein which does NOT require energy
- C.
Movement of water
Correct Answer
A. The movement of particles through a protein which requires energyExplanation
Active transport is the process of moving particles through a protein that requires energy. Unlike passive transport, which does not require energy, active transport uses energy to move particles against their concentration gradient. This process is essential for maintaining proper cellular function and enables the cell to control the movement of specific molecules in and out of the cell.Rate this question:

what is Passive transport?
- A.
Movement of water
- B.
The movement of particles through a protein which does NOT require energy
- C.
The movement of particles through a protein which requires energy
Correct Answer
B. The movement of particles through a protein which does NOT require energyExplanation
Passive transport refers to the movement of particles through a protein without the need for energy. This process occurs along a concentration gradient, where particles move from an area of higher concentration to an area of lower concentration. It is a spontaneous process that does not require the input of energy from the cell.Rate this question:

Correct Answer
A. TrueExplanation
An organ system is indeed a group of organs that collaborate and work together to carry out a particular function in the body. Each organ within the system has a specific role to play, and by working together, they ensure the proper functioning of the body. Examples of organ systems include the respiratory system, digestive system, and circulatory system, among others.Rate this question:

Organism is ?
- A.
Anything which can independently carry out life processes
- B.
Movement of particals through a protein
- C.
The diffusion of water
Correct Answer
A. Anything which can independently carry out life processesExplanation
An organism is defined as anything that can independently carry out life processes. This means that an organism is capable of performing essential functions such as growth, reproduction, metabolism, and response to stimuli without relying on another organism for survival. This definition encompasses a wide range of living entities, including plants, animals, and microorganisms. Organisms can vary greatly in size, complexity, and habitat, but they all share the ability to sustain life processes on their own.Rate this question:

diffusion is?
- A.
The movement of particles from an area of high concentration to low concentration
- B.
The diffusion of water
- C.
A clock
Correct Answer
A. The movement of particles from an area of high concentration to low concentrationExplanation
Diffusion is the process by which particles move from an area of high concentration to an area of low concentration. This occurs due to the random motion of particles and the desire for them to reach a state of equilibrium. As particles move from areas of high concentration to low concentration, they spread out and become evenly distributed. This is a fundamental process in various biological and physical systems, such as the exchange of gases in the lungs and the mixing of substances in a solution.Rate this question:

Semi-permeable is the characteristic of a material which allows only certain materials to pass through it?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because a semi-permeable material selectively allows only certain materials to pass through it while blocking others. This property is commonly observed in biological membranes, such as cell membranes, which regulate the passage of ions and molecules.Rate this question:

Permeable is the characteristic of a material which allows other substance to pass through it?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Permeable materials are those that allow other substances to pass through them. This means that they have small holes or spaces that allow the movement of gases or liquids. Therefore, the statement "Permeable is the characteristic of a material which allows other substances to pass through it" is true.Rate this question:
