Explanation

HbA1c reflects long-term blood glucose levels.

Biguanides, such as Metformin, are commonly used to treat type 2 diabetes to help decrease HbA1c.

HbA1c lowering effect

1. Metformin: Typically reduces HbA1c by 1-2% (11-22 mmol/mol).

2. Sulfonylureas: May reduce HbA1c by 0.5-1.5% (5.5-16.5 mmol/mol).

3. Acarbose: Typically reduces HbA1c by 0.5-1% (5.5-11 mmol/mol).

Explanation

A place that does not have safe oxygen levels is typically referred to as a "Confined Space."

Where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen)

There are two types of confined spaces

• Permit
• Not-Permit

Explanation

• Mitosis is a process of cell division that results in the production of two daughter cells, each with the same number of chromosomes as the parent cell.
• This process is essential for growth, repair, and asexual reproduction in living organisms.

Explanation

• The Forebrain is the largest part of the brain and comprises two hemispheres: the left hemisphere and the right hemisphere. 
• The forebrain includes the cerebrum, which is responsible for processing sensory information, controlling movement, and managing higher-level cognitive functions such as thought, emotion, and memory.

Explanation

The brain is divided into three primary parts:

• Forebrain (includes the cerebrum, thalamus, and hypothalamus)
• Midbrain (connects the forebrain to the hindbrain, and regulates auditory and visual processing)
• Hindbrain (includes the cerebellum, pons, and medulla oblongata, and regulates movement, balance, and basic bodily functions)

Explanation

Tundra is a region with a very cold climate, found in the Arctic and Antarctic regions, characterized by:

• Low temperatures
• Short growing season
• Limited vegetation (mainly low-growing shrubs, grasses, and mosses)
• Permafrost (frozen soil)

Explanation

• The oesophagus (also known as the esophagus) is a muscular tube that acts as a pathway to transport food from the pharynx (throat) to the stomach.
• It uses peristalsis (wave-like muscle contractions) to move the food bolus into the stomach.

Explanation

• Omnivores play a crucial role in ecosystems as they help to regulate populations of both plants and animals.
• They can adapt to different food sources depending on availability.
• Examples: humans, bears, and pigs.
