We hear sound because of sound waves.
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
Answer:
6CO2 + 6H2O → C6H12O6 + 6O2.
Explanation:
This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Energy in a molecule is stored in a metastable state
Answer:
<h2>
Endosymbiotic theory states that some organelles found in eukaryotic cells arises from prokaryotic cells.</h2>
Explanation:
The Endosymbiont theory proposed that mitochondria and chloroplasts evolved from some bacteria that were ingested by primitive nucleated cells. Chloroplast and mitochondria have characteristics similar to bacteria. They divide by binary fission as well as contain single circular DNA and 70s ribosomes found in prokaryotes. It was believed that mitochondria had evolved from some proteobacteria and chloroplast has evolved from cyanobacteria.
