Explanation

• Sound travels fastest in diamond,
• With a speed of approximately 12,000 meters per second (m/s).
• Because sound travels fastest in stiff, dense materials

Additional information 
The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s

Explanation

Explanation

• Self-Pollination is the transfer of mature pollen grains from the anther of one flower to the stigma of the same flower or another flower of the same plant.
• This means that the pollen is transferred within the same plant, allowing for fertilization to occur without the involvement of another plant.

Explanation

• The male reproductive part of a flower is called the Stamen.

It consists of two parts:

1. Anther (produces pollen grains)
2. Filament (supports the anther)

Explanation

• In a parallel circuit, each branch has its own path for current to flow.
• If one branch is interrupted, the other branches will continue to operate normally.

Explanation

• Insects like bees, butterflies, moths, and beetles are important pollinators of plants in gardens.
• They visit flowers to collect nectar and pollen, and in the process, transfer pollen from one flower to another, allowing for fertilization to occur.

Explanation

• In plants, water and minerals are transported from the roots to the leaves through the xylem.
• A type of vascular tissue.

Explanation

• The female reproductive part of a flower is called the Pistil.

It consists of three parts:

1. Stigma (receives pollen grains)
2. Style (connects stigma to ovary)
3. Ovary (contains ovules/eggs)

The pistil is also sometimes referred to as the carpel, which is a modified leaf that forms the female reproductive organ.

Explanation

The K orbit, also known as the first electron shell.

• It can hold a maximum of 2 electrons.

The L orbit, also known as the second electron shell.

• It can hold a maximum of 8 electrons.

The M orbit, also known as the third electron shell.

• It can hold a maximum of 18 electrons.

Explanation

• Carbon dating is used to estimate the age of fossils.
• Those that are less than 60,000 years old.
• It is composed of organic materials like wood or leather.
