Explanation

• Water enters the root hair through the process of osmosis.
• It is the movement of water molecules from a region of high concentration to a region of low concentration through a selectively permeable membrane.

Explanation

• Myocardial Infarction (MI) is the scientific term for a heart attack.
• It occurs when the blood flow to the heart is blocked, causing damage to the heart muscle.

Explanation

• The circulation of blood starts from the right side of the heart.
• Specifically from the right ventricle, which pumps blood into the pulmonary artery and sends it to the lungs to pick up oxygen.

Explanation

• Burning process is a chemical process.
• But it is not a physical process.

The characteristics of the burning process are:

• It is a chemical process.
• It takes place in all living cells.
• It release energy.
• Various enzymes are required.

Explanation

• Breathing (respiration) is a process that requires energy.
• But it does not release energy.

The characteristics of the breathing process are:

• It is a physical process.
• It occurs in the respiratory system.
• It requires energy.
• Enzymes are not involved.

Explanation

• Aerobic respiration is the process of cellular respiration that uses oxygen (O2) to generate energy from glucose.
• It is the primary method of energy production in humans and other animals, and it produces carbon dioxide and water as byproducts.

Explanation

• Anaerobic respiration is a process of cellular respiration that occurs in the absence of oxygen (O2).
• It is used by small microorganisms like fungi and bacteria, as well as muscle cells during intense exercise.
• Anaerobic respiration produces less energy than aerobic respiration and typically results in the production of lactic acid or ethanol and carbon dioxide.

Explanation

• During exhalation, the diaphragm relaxes and moves upwards.
• It decreasing the volume of the thoracic cavity and allowing air to leave the lungs.

Explanation

• When the rhythmic action of the digestive tract (peristalsis) speeds up.
• It can lead to diarrhea.

Explanation

• When the rhythmic action of the digestive tract (peristalsis) slows down, it can lead to constipation.
• Peristalsis is the coordinated muscle contraction and relaxation that moves food through the digestive system.
