Explanation

Ammonia has a pH level of around 11-12, which is strongly alkaline (basic).

Explanation

The equation A+B → AB represents an addition reaction, where two substances (A and B) combine to form a new compound (AB).

Explanation

• The Second is the SI unit of time.
• It is defined as 9,192,631,770 periods of a caesium-133 atom's radiation.

Explanation

• The pressure exerted by a gas is a result of the countless collisions of gas molecules with the container walls, which transfer momentum.
• It force to the walls, causing pressure.
• This is a fundamental principle in kinetic molecular theory.

Explanation

The pH scale ranges from 1 to 14, with:

• 1-6 being acidic
• 7 being neutral (neither acidic nor basic)
• 8-14 being basic (alkaline)

Explanation

• Hydrogen and Oxygen combining to form water, which is an example of a synthesis reaction: 2H2 + O2 → 2H2O
• In this reaction, two substances (hydrogen and oxygen) combine to form a new compound (water).

Explanation

• During Metaphase, the chromosomes align at the center of the cell, attached to the spindle fibers formed by the centrioles (also known as microtubules).
• This is the stage where the chromosomes are connected to the spindle fibers, preparing for separation.

Explanation

The Forebrain, specifically the cerebrum, is responsible for controlling higher-level functions such as:

• Thinking
• Feelings
• Memory
• Hearing
• Seeing
• Speech
• Decision making

Explanation

The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.

Explanation

• The Midbrain is the smallest part of the brain, connecting the forebrain to the hindbrain.
• It plays a crucial role in auditory and visual processing, as well as body movement and coordination.
