What causes the sound in a seashell?
- A.
Echo Effect
- B.
Micro-organisms Living In Shell
- C.
Sound Of Blood From Ear
- D.
Resonance Effect

D. Resonance EffectExplanation
The sound in a seashell is caused by the resonance effect. When sound waves enter the seashell, they bounce off the inner surface and create a resonance, causing the sound to amplify and become more audible. This phenomenon is similar to how sound resonates in a musical instrument, such as a guitar or a violin. The shape and structure of the seashell contribute to the resonance effect, allowing us to hear the sound when we hold it up to our ear.Rate this question:

February
- B.
March

Correct Answer
B. MarchExplanation
In the United States, spring begins in March. This is because the seasons in the Northern Hemisphere are determined by the tilt of the Earth's axis. In March, the Earth starts to tilt towards the sun, resulting in longer days and warmer temperatures. This transition from winter to spring is marked by the blooming of flowers, the return of migratory birds, and the melting of snow. Therefore, March is the correct answer for when spring begins in the United States.Rate this question:

- D.
Marble
Correct Answer
C. SandstoneExplanation
Sandstone is a sedimentary rock composed primarily of sand-sized grains. It is formed from the accumulation and cementation of individual sand particles, which are usually made up of quartz or feldspar minerals. The grains are compacted and bound together by a cementing material, such as silica, calcite, or iron oxide. Sandstone is commonly found in areas where there has been deposition of sand, such as beaches, riverbeds, and deserts. It is a durable rock that is often used as a building material and for decorative purposes.Rate this question:

Sporophyte

When a plant produces two kinds of sex cells, it is called gametophyte. The gametophyte is the sexual phase in the life cycle of a plant, where it produces male and female sex cells (gametes). This is different from sporophyte, which is the asexual phase where spores are produced. Chlorophyll is a pigment responsible for the green color in plants, and rhizoid is a structure that anchors a plant to the ground.Rate this question:

What is a plant with no internal system of tube-like structures called?
- A.
Accessory Pigment
- B.
Nonvascular Plant
- C.
Vascular Tissue
- D.
Vascular Plant
Correct Answer
B. Nonvascular PlantExplanation
A plant with no internal system of tube-like structures is called a nonvascular plant. Nonvascular plants, such as mosses and liverworts, lack specialized tissues for transporting water and nutrients. Instead, they rely on direct absorption from their surroundings. This adaptation limits their size and prevents them from growing very tall. Nonvascular plants are typically found in moist environments where they can easily absorb water and nutrients through their entire surface.Rate this question:

Humans have been around for what % of the Earth's history?
- A.
15%
- B.
2%
- C.
0.00%
- D.

The answer is 0.00% because humans have only been present on Earth for a relatively short period of time compared to the overall history of the planet. The Earth is estimated to be around 4.5 billion years old, and the earliest evidence of human existence dates back to only about 200,000 years ago. Therefore, the percentage of time that humans have been around is negligible in comparison to the entire history of the Earth.Rate this question:
