B) P and S waves cannot travel through liquids.
C) P and S waves travel through liquids at different speeds.
D) S waves cannot travel through liquids.
The Earth’s interior is composed of several layers: the crust, the mantle and the core. Scientists used waves and their speed to study the Earth's interior. The speed of seismic waves is affected by the properties of the material the waves pass through. The stiffness of material affects the speed of these waves. P-waves, or pressure waves, go through both liquids and solids, while S-waves, or shear waves go through solids but not liquids. The following helped scientists understand that Earth's interior is liquid: S waves cannot travel through liquids. Correct answer: D
Sunflowers are producers. A food web includes sunflowers as both producers and consumers. Sunflowers help the soil's food chain replenish its energy. Only herbivores in the food chain use sunflowers as a source of food and energy.
Sunflowers are producers, placing them at the base of the food chain and at the top of a food web. Numerous insects, particularly tiny omnivores, depend on sunflowers for food, energy, and shade. As an illustration, numerous birds eat the seeds it produces, and caterpillars eat the huge leaves it produces.
The abundant seeds that sunflowers generate can be used in salads, baked into bread, or even made into a smooth nut-free sunflower butter. You'll get a bigger crop of edible plants if you grow a kind that produces seeds.
Therefore, sunflowers are producers.

• Use a hose to sprinkle water on the mountain.
• Observe the change in the shape of the mountain.
The experiment most likely demonstrates the interactions between the
1) atmosphere and biosphere
2)biosphere and hydrosphere
3) geosphere and biosphere
4) hydrosphere and geosphere
The experiment most likely illustrates how the atmosphere and biosphere interact. As a result, choice (A) is the best way to respond.
A layer (or layers) of gases that encircle a planet and are maintained in place by the gravity of the celestial body is known as an atmosphere.When there is a strong gravitational pull and a cool atmosphere, a planet keeps its atmosphere. The outer region of a star, including the layers above the opaque photosphere, is known as the stellar atmosphere; low-temperature stars may have outer atmospheres with complex molecules.
Nitrogen makes up 78% of the atmosphere of Earth, along with oxygen (21%), argon (0.9%), carbon dioxide (0.04%), and trace gases. The majority of species require oxygen for respiration, whereas plants and algae use carbon dioxide for photosynthesis and lightning and bacteria execute nitrogen fixation to create ammonia, which is used to create nucleotides and amino acids.
Hence, option (A) is accurate.
