One student did an experiment on the rock cycle. The steps of the experiment are shown below.

• Half fill a glass bottle with pieces of granite.

• Pour dilute acid into the bottle to submerge all the granite pieces.

• After a week pour off the acid.

Shake the bottle vigorously for two minutes.

• Filter the contents of the bottle into a dish of water.

• Leave the dish undisturbed for an hour.

• Put two heavy weights on the material in the dish for a week.

What does the student's experiment most likely demonstrate about the rock cycle?

A) Pressure can cause melting of rocks to form igneous rocks.

B) Pressure can crystallize dissolved rocks to form sedimentary rocks.

C) A series of steps can cause weathering of rocks to form sedimentary rocks.

D) A series of steps can transform rocks into magma which cools to form igneous rocks.

Leslie argues that an organism called a Euglena is a plant because it is eukaryotic, has a nucleus, makes its own food, and is unicellular. Where is Leslie's error? Plants do not make their own food..

One parrot species that feeds on large seeds nests is in the same tree as a parakeet that feeds on small seeds, they occupy different niches.

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis.

 Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.

Example with explaination :

The processes of conduction, convection and radiation help distribute energy on earth...

Answer: Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms.

They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem's primary producers—usually plants and algae.

He solved Ptolemy's model by providing elliptical orbits.he determined that planets travels faster when closer to sun.
