Explanation

The rate of evaporation can be increased by:

• Decreasing atmospheric pressure
• Increasing temperature
• Decreasing humidity
• Increasing the surface area of the liquid

Explanation

• Organic chemistry is the branch of chemistry that deals with hydrocarbons and their derivatives.
• They are compounds containing carbon and hydrogen atoms.
• It may also contain other elements like oxygen, nitrogen, and sulfur.

Explanation

Both 1.01 and 0.124 have three significant figures.

All non-zero digits and zeros between non-zero digits count as significant figures.

Explanation

• If the pH value is greater than 7, the solution is basic (also known as alkaline).
• This means that the concentration of hydroxide ions (OH-) is higher than the concentration of hydrogen ions (H+).

Key Points:

• pH < 7: Acidic
• pH = 7: Neutral
• pH > 7: Basic (or alkaline)

Explanation

Mitosis is a type of cell division that involves the replication of a cell's DNA and the division of the cell into two daughter cells. It is essential for:

• Growth: Mitosis allows an organism to grow and develop by increasing the number of cells.
• Repair: Mitosis helps replace damaged or dead cells with new ones.
• Asexual reproduction: Mitosis enables asexual reproduction, where an organism produces offspring that are genetically identical to the parent.

Explanation

Root hairs are thin, hair-like structures that extend from the roots of plants, increasing the surface area for absorption of water and nutrients from the soil. They play a crucial role in:

• Absorbing water and minerals
• Anchoring the plant in the soil
• Facilitating the uptake of nutrients
