Explanation

Systematic errors are caused by faulty or improper functioning of instruments, or by a flaw in the experimental design.

These errors are consistent and repeatable, and can be identified and corrected.

Explanation

• The general formula for alkanes is CnH2n+2, where n is the number of carbon atoms in the molecule.
• This formula represents the saturated hydrocarbons, also known as paraffins.

Key Points:

• CnH2n is the general formula for alkenes
• CnH2n+1 is the general formula for alcohols

Explanation

The cerebellum is responsible for:

• Coordinating movements
• Maintaining posture and balance
• Regulating muscle tone
• Learning new motor skills
• Precision and accuracy in movements

Explanation

Homeostasis is the set of metabolic reactions that maintain the internal environment of an organism, regulating factors.

Such as temperature, pH, blood sugar levels, and blood pressure.

Explanation

A NOT gate, also known as an inverter.

It is a digital logic gate that negates the input signal.

If the input is "1", the output will be "0".

If the input is "0", the output will be "1".

The truth table for a NOT gate is:

Input | Output

-----|------

0 | 1

1 | 0

Explanation

The respiratory surface, where gas exchange occurs, is the alveoli.

Alveoli are tiny sacs located at the end of the bronchioles, deep in the lungs.

They provide a large surface area for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.

Explanation

Explanation

Glucose (C6H12O6) is a type of carbohydrate, specifically a simple sugar or monosaccharide.

It is a vital source of energy for many living organisms, including humans.

Glucose is a primary component of many carbohydrates, such as starch, cellulose, and glycogen.

Explanation

The approximate value of the speed of sound in air at 0°C is 332 m/s.

This value is based on standard atmospheric conditions

They vary slightly with changes in temperature and pressure.

Explanation

Lactose, also known as milk sugar.

It is a disaccharide composed of galactose and glucose molecules.

It is found in milk and other dairy products.
