Explanation

The Hindbrain is divided into three main parts:

• Medulla Oblongata (controls breathing, heart rate, and blood pressure)
• Pons (involved in controlling sleep and arousal)
• Cerebellum (coordinates movement, balance, and learning)

Explanation

• The alimentary canal, also known as the gastrointestinal (GI) tract, is a continuous tube that extends from the mouth to the anus.
• It includes all the organs of the digestive system.

Explanation

• Small Vacuole because plant cells typically have a large central vacuole, not small vacuoles.

The components of a plant cell:

• Cell wall
• Cell membrane
• Cytoplasm
• Large vacuole
• Nucleus
• Chromosomes
• Chloroplast

Explanation

• Diffusion is the random movement of particles from a region of higher concentration to a region of lower concentration, resulting in uniform distribution.
• In this case, the ink particles spread out and mix with the water particles, causing the color to disperse throughout the glass.

Explanation

• Cholera is a waterborne disease caused by the bacterium Vibrio cholerae, which is typically found in contaminated water sources.
• If a child has cholera, it indicates that they have ingested contaminated water.
• It addressing water pollution is crucial to prevent further spread of the disease.

Water pollution can cause:

• Waterborne diseases (cholera, typhoid, diarrhea)
• Death of aquatic life (fishes, animals, plants)
• Health problems (immune depression, reproductive failure, acute poisoning)

Explanation

• Hypogeal germination occurs in monocotyledonous seeds (Monocot Seed).
• Where the cotyledon remains underground and the plumule emerges above the soil surface.
• Examples of monocot seeds include maize, wheat, rice, and grasses.

Explanation

• Plants are multicellular, composed of many cells that work together to form roots, stems, leaves, and other structures.
• They have modified cell wall and nucleus.
• They have chlorophyll.
• Algae are unicellular with proper cell wall and nucleus.
• It contain chlorophyll.
• It causes diseases: Cutleria, Ulva and Volvox.

Explanation

In the event of a nuchal cord, cutting the cord between clamps may be necessary

if the cord is tightly wrapped around the baby's neck

And is causing significant compression or compromising the baby's well-being.

This intervention helps to ensure the safe delivery of the baby. 

Explanation

Cyanosis in the tetralogy of Fallot is primarily due to the combination of the four defects, with pulmonary stenosis playing a crucial role.

Pulmonary stenosis restricts blood flow to:

• the lungs
• increasing pressure in the right ventricle 
• leading to a right-to-left shunt through the ventricular septal defect

This shunt allows deoxygenated blood to enter the systemic circulation, causing cyanosis.

Explanation

Magnesium deficiency can contribute to or exacerbate all of the following health issues:

• Painful joints: Magnesium helps regulate inflammation and muscle function, and deficiency can lead to joint pain and stiffness.
• Osteoporosis: Magnesium is essential for bone mineralization and density; deficiency can increase the risk of osteoporosis and fractures.
• Memory loss: Magnesium plays a role in neuronal function and synaptic plasticity; deficiency has been linked to cognitive impairment and memory loss.
• Diabetes: Magnesium helps regulate insulin sensitivity and glucose metabolism; deficiency can increase the risk of developing type 2 diabetes.

Additionally, magnesium deficiency can also lead to other health issues, such as:

• Muscle cramps and weakness
• Fatigue and lethargy
• Cardiovascular problems, including high blood pressure and arrhythmias
• Weakened immune system
• Neurological symptoms, such as anxiety, depression, and seizures
