Explanation

• The technique of growing plants with their roots suspended in the air is called aeroponics.
• Aeroponics is a type of hydroponics, as water is employed in aeroponics to deliver nutrients to the plants, and is also known as "air culture".
• The roots are suspended in the air and sprayed with nutrient solutions.

Explanation

• Folic acid is the most essential nutrient for a woman during her initial stages of pregnancy to prevent birth defects.
• It plays a crucial role in preventing neural tube defects in the developing fetus.

Explanation

The pea plant (Pisum sativum) has 7 pairs of homologous chromosomes, i.e., 14 chromosomes in total.

This was the organism used by Gregor Mendel in his foundational genetics experiments.

Explanation

The foot has:

• 7 tarsal bones
• 5 metatarsal bones
• 14 phalanges (toe bones)

The hand has:

• 8 carpal bones
• 5 metacarpal bones
• 14 phalanges (finger bones)

Explanation

"salt" (high sodium intake) is considered a significant contributor to renal failure

High blood pressure link:

Excessive salt intake can contribute to high blood pressure, which puts stress on the kidneys and can lead to kidney damage. 

Proteinuria:

High salt intake can increase the amount of protein leaked into the urine (proteinuria), a sign of kidney dysfunction. 

Progression of kidney disease:

For people with existing kidney disease, a high salt diet can worsen their condition and accelerate the progression to renal failure. 

Explanation

The pituitary gland is located at the base of the brain.

It is below the hypothalamus.

It sits in a hollowed-out area of the sphenoid bone called the sella turcica.

Explanation

Plants absorb sunlight to produce oxygen (O2) and glucose (C6H12O6) through photosynthesis.

This process occurs in chloroplasts, where light energy is converted into chemical energy.

Explanation

Darwin himself bred pigeons.

He used selective breeding of pigeons to study and demonstrate the principles of natural selection and variation in species.

Explanation

• The pons is a bridge-like structure that links different parts of the brain.
• It connecting the midbrain to the medulla oblongata.

Explanation

The Central Nervous System (CNS), which includes the brain and spinal cord, controls all the vital functions necessary for living, including:

• Breathing
• Maintaining body temperature
• Thinking
• Feelings
• Heartbeat
