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

• When the rectangular piece of wood is kept in position A.
• Its entire weight is concentrated on a smaller area, resulting in maximum pressure on the table.

Explanation

• Cell division is the process by which a cell splits into two daughter cells, resulting in the multiplication of new cells.
• This process is essential for growth, development, and tissue repair in living organisms.

Explanation

• The Peripheral Nervous System (PNS) consists of nerves that connect the Central Nervous System (CNS) to the rest of the body.
• It enabling communication and transmission of signals.

Explanation

The Brain is the "boss" of the human body, serving as the control center for all bodily functions, including:

• Movement
• Sensation
• Perception
• Emotions
• Thoughts
• Regulation of various bodily systems

Explanation

• The iris is the colored part of the eye that controls the amount of light entering the eye, much like a diaphragm in a camera.
• It adjusts its aperture (pupil) to regulate the amount of light that reaches the retina.

Explanation

• The formation of hydrogen and oxygen from water, which is an example of a decomposition reaction: 2H2O → 2H2 + O2
• In this reaction, water (H2O) decomposes into hydrogen (H2) and oxygen (O2).

Explanation

• Uracil (U) is not a base found in DNA.
• Instead, it is found in RNA (ribonucleic acid), where it replaces Thymine (T).

The four organic bases found in DNA are:

1. Adenine (A)
2. Cytosine (C)
3. Thymine (T)
4. Guanine (G)
