The main force causing water to flow from the roots to the leaves is:

Root pressure
Respiration
Capillaries
Transpiration

Correct Answer

A. Root pressure

Explanation

The main force causing water to flow from the roots to the leaves is root pressure. Root pressure is the result of osmotic pressure in the root cells, which pushes water up through the xylem vessels. This pressure is created when minerals and ions are actively pumped into the root cells, creating a higher solute concentration inside the roots compared to the surrounding soil. As a result, water moves into the root cells by osmosis, generating pressure that pushes water upwards. Root pressure is particularly important in small plants and during periods of low transpiration.

Which one of the following does not form part of the axial skeleton?

Skull
Clavicle
Sternum
Vertebrae

Correct Answer

A. Clavicle

Explanation

The clavicle does not form part of the axial skeleton. The axial skeleton consists of the skull, sternum, and vertebrae, which are all located along the central axis of the body. The clavicle, also known as the collarbone, is part of the appendicular skeleton, which includes the bones of the limbs and the girdles that connect them to the axial skeleton.

________ is a plant tissue that transport food from the leaves to the stem and root.

Correct Answer
phloem

Explanation
Phloem is a plant tissue that transports food from the leaves to the stem and root. It is responsible for conducting sugars, amino acids, and other organic compounds produced during photosynthesis to other parts of the plant. This transportation occurs through specialized cells called sieve tube elements, which are connected end-to-end to form long tubes. The movement of food in phloem is bidirectional, allowing nutrients to be distributed to areas of the plant where they are needed for growth and metabolism.

________ is a type of epithelial tissue that forms the lining of the inner surface of the mouth, oesophagus and blood vessels.

Correct Answer
squomous epithelium

Explanation
Squamous epithelium is a type of epithelial tissue that lines the inner surface of the mouth, esophagus, and blood vessels. This type of tissue is composed of flat, scale-like cells that are tightly packed together. Its main function is to provide protection and act as a barrier against mechanical and chemical damage. Squamous epithelium is well-suited for areas that experience friction and wear, such as the mouth and esophagus, as its structure allows for easy movement and flexibility. Additionally, its presence in blood vessels helps to facilitate smooth blood flow.

________ are neurons that transmit nerve impulses from the sensory organs to the central nervous system.

Correct Answer
sensory neurons

Explanation
Sensory neurons are responsible for transmitting nerve impulses from the sensory organs to the central nervous system. These specialized neurons play a crucial role in relaying sensory information such as touch, taste, smell, sight, and sound to the brain for processing. They allow us to perceive and interpret the external environment, enabling us to respond accordingly. Without sensory neurons, our ability to sense and interact with the world around us would be greatly impaired.

________ is a part of the medulla that occur in-between the vascular bundles of the dicotyledonous stem.

Correct Answer
cambium

Explanation
The given correct answer, cambium, is a part of the medulla that occurs in-between the vascular bundles of the dicotyledonous stem. The cambium is a thin layer of meristematic tissue that is responsible for secondary growth in plants. It produces new cells that differentiate into xylem and phloem, which are essential for the transport of water, nutrients, and sugars throughout the plant. The cambium is located between the primary xylem and phloem, and it plays a crucial role in increasing the girth of the stem over time.

________ is a skeleton formed by a coelom (fluid-filled space).

Correct Answer
hydroskeleton

Explanation
A hydroskeleton is a skeletal structure that is formed by a coelom, which is a fluid-filled space. This type of skeleton provides support and structure to certain organisms, such as jellyfish and worms, by using the pressure of the fluid to maintain their shape. The fluid-filled coelom allows for flexibility and movement in these organisms.

Attaches bone to bone:

Tendons
Ligaments
Both tendons and ligaments

Correct Answer

A. Tendons

Explanation

Tendons are fibrous connective tissues that attach muscle to bone. They play a crucial role in facilitating movement by transmitting the force generated by muscles to the bones, allowing for joint movement. Ligaments, on the other hand, connect bone to bone and provide stability to joints. While both tendons and ligaments are important for the overall function and structure of the musculoskeletal system, tendons specifically attach bone to bone, making them the correct answer in this case.

Stem cells:

Non-differentiated cells
Somatic cells
All of the above
None of the above

Correct Answer

A. All of the above

Explanation

The correct answer is "all of the above" because stem cells are non-differentiated cells that have the potential to develop into different types of cells in the body. They can be found in various sources, including somatic cells, which are non-reproductive cells in the body. Therefore, all the options provided - non-differentiated cells and somatic cells - accurately describe stem cells.

The skeletal system is made up of:

Appendicular
Axial
All of the above
None of the above

Correct Answer

A. All of the above

Explanation

The skeletal system is made up of two main parts: the appendicular skeleton and the axial skeleton. The appendicular skeleton includes the bones of the limbs, such as the arms and legs, as well as the shoulder and pelvic girdles. The axial skeleton includes the bones of the skull, spine, and ribcage. Therefore, the correct answer is "all of the above" because both the appendicular and axial skeletons are part of the skeletal system.

Goblet cells:

Tip of nose
Supportive connective tissue
All of the above
None of the above

Correct Answer

A. None of the above

Explanation

The correct answer is "none of the above" because goblet cells are a type of specialized columnar epithelial cells that are found in the respiratory and digestive tracts. They are responsible for producing and secreting mucus, which helps to protect and lubricate the lining of these organs. Goblet cells are not found in the tip of the nose or in supportive connective tissue.
