Explanation

DNA replication is the process by which a cell makes an exact duplicate of its DNA before cell division.

This process involves the unwinding of the double helix, the synthesis of a new complementary strand.

The formation of two identical daughter molecules.

Explanation

Rickets is a condition that affects children, causing softening and weakening of bones due to a deficiency of vitamin D, calcium, or phosphorus.

This leads to bowed legs, stunted growth, and other skeletal deformities.

Explanation

Transpiration is the process by which plants remove excess liquid water from their tissues and release it into the air as water vapor.

This process occurs mainly through the leaves and stems of plants and is an important part of the water cycle.

Explanation

Alpha (α) radiation consists of heavy, positively charged particles (alpha particles) that are emitted from the nucleus of an atom during certain types of radioactive decay.

Alpha particles are highly ionizing, meaning they can efficiently remove tightly bound electrons from atoms, resulting in the formation of ions.

Explanation

The Boolean expression for an OR gate is A + B, where A and B are the inputs.

This expression reads "A or B".

In Boolean algebra, the OR operation is represented by a plus sign (+) or a logical disjunction symbol (∨).

So, the expression A + B or A ∨ B represents the OR operation.

Explanation

Preservatives are used to prevent the growth of microorganisms, such as bacteria, yeast, and mold, in food.

They help to extend the shelf life of food products and prevent spoilage.

Preservatives can be found in meats, dairy products, baked goods, and beverages.

Explanation

Inheritance refers to the transmission of traits or characteristics from parents to offspring through the passing down of genetic information.

It's the process by which genetic traits are inherited.

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

Resistance is the property of a material or object that opposes the flow of electric charge (current) through it.

It is measured in ohms (Ω) and depends on the material, length, and cross-sectional area of the object.

Explanation

Ginger has rhizomes, which are horizontal underground stems that can give rise to new plants, allowing it to propagate vegetatively.
