Correct Answer
C. An organism which is made of more than one cellExplanation
Multicellular refers to an organism that is composed of multiple cells. This means that the organism has different specialized cells that work together to carry out various life processes. Unlike unicellular organisms, which are made up of only one cell, multicellular organisms have a higher level of complexity and organization. The cells in multicellular organisms are specialized to perform specific functions, such as muscle cells for movement or nerve cells for communication. This organization allows multicellular organisms to have a higher level of complexity and perform more complex tasks.Rate this question:

- 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 is responsible for controlling the movement of materials in and out of the cell. It acts as a barrier, allowing certain substances to pass through while keeping others out. This selective permeability is crucial for maintaining homeostasis and regulating the internal environment of the cell. The cell membrane also plays a role in cell communication and recognition, as it contains various proteins and receptors that interact with other cells and molecules.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 have a hydrophilic (water-loving) head and hydrophobic (water-fearing) tails, which allows them to form a bilayer in cell membranes. This arrangement creates a selectively permeable barrier that controls the movement of substances into and out of the cell. Phospholipids also play a crucial role in the formation of vesicles, which transport materials within the cell. Therefore, the statement "Phospholipids is a type of molecule which regulates the transport of materials" is true.Rate this question:

- 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 is a cell that has a specific function to perform within an organism. Unlike other cells, which may have more general functions, specialized cells are uniquely adapted to carry out specific tasks. These cells are often found in multicellular organisms and work together to form tissues, organs, and organ systems. Examples of specialized cells include red blood cells, which are specialized for carrying oxygen, and nerve cells, which are specialized for transmitting electrical signals.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 by which particles are moved through a protein, such as a membrane protein, against their concentration gradient. This movement requires energy, usually in the form of ATP (adenosine triphosphate), to be expended in order to drive the transport process. Unlike passive transport, which does not require energy and occurs along the concentration gradient, active transport allows particles to be transported from an area of lower concentration to an area of higher concentration. This process is essential for various cellular functions, such as nutrient uptake and waste removal.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 requiring any energy. This process occurs along a concentration gradient, where particles move from an area of higher concentration to an area of lower concentration. Unlike active transport, which requires energy, passive transport relies on the natural movement of particles to achieve equilibrium. This can happen through various mechanisms such as diffusion, osmosis, or facilitated diffusion, where proteins act as channels or carriers to facilitate the movement of particles across the cell membrane.Rate this question:

a Organ is a group of tissues which work together to perform a specific function?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
An organ is indeed a group of tissues that work together to perform a specific function. Tissues are groups of cells that have a similar structure and function, and when different types of tissues come together, they form an organ. Each organ has a specific role in the body and contributes to the overall functioning of the organism. Therefore, the statement that an organ is a group of tissues working together to perform a specific function is correct.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 tendency for them to spread out and achieve a more uniform distribution. This movement continues until equilibrium is reached, where the concentration of particles is the same throughout the system. Diffusion is a fundamental process in various biological, chemical, and physical systems, and it plays a crucial role in processes such as gas exchange in the lungs and the movement of nutrients across cell membranes.Rate this question:
