Explanation

The autonomic nervous system (ANS), also known as the visceral nervous system.

It regulates involuntary vital functions essential for survival, such as:

• Heart rate
• Blood pressure
• Respiration
• Digestion
• Body temperature
• Pupil dilation and constriction

Explanation

• The sequence of physiological changes by which a cell commits suicide is called apoptosis.
• This is a controlled, programmed cell death process that is crucial for maintaining healthy tissue function and development.

Explanation

Neuroblastoma is one of the common childhood tumors.

It's a type of cancer that arises from immature nerve cells

Typically affects young children, usually before the age of 5.

Explanation

 Damage to the cerebellum as a result of injury most likely causes poor coordination of movements. 

The cerebellum is primarily responsible for coordinating muscle movements, balance, and fine motor control.

So, damage to this area would lead to clumsiness, an unsteady gait, and difficulty with precise movements. 

Explanation

Explanation

Peristalsis is a wave of rhythmic movements of muscle contraction and relaxation that helps move substances through a tubular structure, like the digestive tract.

It's a vital process that facilitates the transport of food, water, and waste products through the digestive system.

Explanation

Enzymes lower the activation energy, allowing the reaction to proceed faster and more efficiently.

This enables the reaction to occur with less energy input, making it more feasible and rapid.

Explanation

Electron microscopes produce higher-resolution images due to the shorter wavelength of electrons compared to visible light.

This enables them to reveal smaller details and structures that are not visible with light microscopes.

Explanation

The magnification of a light microscope is formed by a combination of the eyepiece and objective lens.

The objective lens collects and magnifies light from the sample.

It is then further magnified by the eyepiece, producing the final magnification.

Explanation

A ratio is a comparison of two values, often expressed as a fraction or a decimal.

It shows the relative size or quantity of one value in relation to another.

For example: A ratio of 3:4 (or 3/4) compares two values, 3 and 4.
