Cellular drinking, which is the cells' ability to ingest from liquids, is also called ...
- A.
Phagocytosis
- B.
Pinocytosis
- C.
Osmosis
- D.
Active transport
Correct Answer
B. PinocytosisExplanation
Pinocytosis is the process by which cells take in fluids and dissolved substances by forming small vesicles. It is a form of endocytosis, where the cell membrane invaginates and engulfs the fluid, bringing it into the cell. This process allows cells to take in nutrients and other molecules from their environment. Phagocytosis, on the other hand, is the process of engulfing solid particles, while osmosis is the movement of water across a semi-permeable membrane, and active transport is the movement of molecules against their concentration gradient using energy.Rate this question:

Protein synthesis in the cell is handled by ...
- A.
Endoplasmic Reticulum
- B.
Lysosomes
- C.
Mitochondria
- D.
Ribosomes
Correct Answer
D. RibosomesExplanation
Ribosomes are responsible for protein synthesis in the cell. They are small structures found in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information stored in the DNA and use it to assemble amino acids into proteins. They play a crucial role in translating the genetic code and are essential for the production of proteins, which are vital for the cell's structure and function. Therefore, ribosomes are the correct answer for this question.Rate this question:

Chromatin fibres are also known as ...
- A.
Chromosomes
- B.
Centrosomes
- C.
Chromatids
- D.
Centrioles
Correct Answer
C. ChromatidsExplanation
Chromatids are the correct answer because chromatids are condensed forms of DNA that are connected at the centromere. During cell division, chromatids separate and become individual chromosomes. Chromatin fibres, on the other hand, are the uncondensed form of DNA that exist in the nucleus of a non-dividing cell. Centrosomes and centrioles are structures involved in cell division and play a role in organizing the spindle fibers during mitosis, but they are not directly related to chromatin fibres.Rate this question:
-
- 12.

- A.
Prophase
- B.
Metaphase
- C.
Anaphase

Anaphase - at this stage, centromere divides, identical chromosomes move apart breaking spindle structureRate this question:
-
- 13.
Lysosomes are the cell organelles which play a central role in cell division
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Lysosomes are small structures that remove unwanted particles through the use of enzymes. The organelles which play a central role in cell division are called Mitochondria; they extract nutrients/oxygen and create Adenosine Triphosphate (ATP) for energyRate this question:
-
- 14.
The nervous tissue cells cannot reproduce when damaged
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Nervous tissue cells, also known as neurons, are unable to reproduce when damaged. Unlike other cells in the body, neurons do not undergo cell division to replace damaged or lost cells. This is due to their unique structure and function in transmitting electrical signals. Once a neuron is damaged, it cannot be replaced, leading to permanent loss of function in that area. Therefore, the statement "The nervous tissue cells cannot reproduce when damaged" is true.Rate this question:
-

Carbon
- C.
Hydrogen
- D.
Phosphorus
- E.
Oxygen
- F.
Nitrogen
Correct Answer(s)
B. Carbon
C. Hydrogen
E. Oxygen
F. NitrogenExplanation
These four elements, carbon, hydrogen, oxygen, and nitrogen, are considered major elements in the body because they make up a significant portion of the body's composition. Carbon is the building block for organic molecules, while hydrogen and oxygen are essential for various biological processes, including energy production and maintaining cellular structure. Nitrogen is a crucial component of proteins and nucleic acids, which are essential for the growth and functioning of cells. Together, these elements play vital roles in the structure, function, and metabolism of the human body.Rate this question:
-

During mitosis, centrioles divide and go to sides of cells at Prophase
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
During mitosis, centrioles play a crucial role in organizing the spindle fibers that help separate the chromosomes. At the beginning of mitosis, during prophase, the centrioles duplicate and migrate to opposite ends of the cell. This ensures that each daughter cell will have a complete set of centrioles to aid in the formation of the spindle fibers and subsequent chromosome separation. Therefore, the statement "During mitosis, centrioles divide and go to sides of cells at Prophase" is true.Rate this question:

- F.
Fascia
Correct Answer(s)
A. Loose
C. Dense
F. FasciaExplanation
The correct answer is Loose, Dense, and Fascia. Connective tissue is categorized into different types based on their structure and function. Loose connective tissue is characterized by loosely arranged fibers and serves as a support for organs and blood vessels. Dense connective tissue has densely packed fibers and provides strength and support to various body parts. Fascia is a type of connective tissue that forms a protective sheath around muscles, bones, and organs. Epithelial and elastic tissues are not types of connective tissue, so they are not included in the answer.Rate this question:

False
Correct Answer
A. TrueExplanation
The fibrous membrane that protects the bone surface is known as the periosteum. This membrane covers the outer layer of the bone and contains blood vessels, nerves, and cells that are involved in bone growth and repair. It helps to nourish the bone and serves as an attachment point for ligaments and tendons.

Cancellous bone has larger Harvesian canals but fewer Lamellae than Compact bone
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Cancellous bone, also known as spongy or trabecular bone, is characterized by larger Haversian canals, which are channels that contain blood vessels and nerves. These canals are responsible for the transport of nutrients and waste products within the bone. On the other hand, compact bone, also known as cortical bone, has smaller Haversian canals. Additionally, cancellous bone has fewer lamellae, which are concentric layers of bone matrix, compared to compact bone. This is because cancellous bone has a more porous and less organized structure, providing a larger surface area for metabolic activities. Therefore, the statement that cancellous bone has larger Haversian canals but fewer lamellae than compact bone is true.Rate this question:
