Explanation

• The artificial kidney machine is called Hemodialysis.
• It filters waste products and excess fluids from the blood when the kidneys are unable to perform this function adequately.

Explanation

• When food is mixed with saliva and chewed, it is broken down into a soft, flexible, semi-solid mass called a bolus.
• This bolus is then swallowed, and it passes through the esophagus into the stomach.

Explanation

• C6H12O6 + 6O2 → 6CO2 + 6H2O
• This is the correct equation for cellular respiration in plants, where glucose (C6H12O6) is broken down to produce carbon dioxide (CO2) and water (H2O), releasing energy in the process.

Explanation

• The large vacuole is a membrane-bound organelle found in plant cells that stores water, salts, sugars, and other substances.
• It plays a crucial role in maintaining cell turgor pressure, supporting cell growth, and storing nutrients and waste products.

Explanation

Monocot plants are characterized by:

• Leaves with parallel venation
• Seeds with one cotyledon
• Flowers with three or a multiple of three floral leaves

Having flowers with four or a multiple of four floral leaves is actually a characteristic of dicot plants, not monocots.

Explanation

Most neurons in the central nervous system (CNS) are multipolar, meaning they have multiple dendrites and a single axon.

Explanation

• The environment refers to the natural world that surrounds us, including all living and non-living things.
• Such as plants, animals, water, air, soil, and sunlight.

Explanation

Sodium plays a crucial role in regulating the distribution of water in the body, as it helps control the amount of fluid in cells, tissues, and organs. It does this by:

• Regulating fluid balance and blood pressure
• Maintaining proper osmotic balance
• Facilitating the transport of water and nutrients into cells

Sodium helps distribute water throughout the body, which is essential for various bodily functions, such as:

• Maintaining healthy blood pressure
• Supporting nerve and muscle function
• Regulating body temperature
• Facilitating waste removal

Explanation

Iron deficiency can lead to Anaemia, a condition characterized by:

• Low red blood cell count
• Pale skin
• Fatigue
• Shortness of breath
• Dizziness

Explanation

• Protein is referred to as "body building" food.
• Because it provides the necessary building blocks for growth, maintenance, and repair of tissues in the body.
• It is essential for building and repairing muscles, bones, skin, hair, and nails, as well as producing enzymes and hormones.
