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:
The atomic number is 79 and the atomic mass is 197.
Explanation:
The atomic number (symbol Z) of a chemical element is the number of protons within its nucleus.
Gold (chemical symbol Au) is a chemical element with 79 protons in its nucleus, therefore with atomic number 79.
The atomic mass is the average mass of the atoms of an element (in atomic mass unit). The atomic mass is the weighted average of all the isotopes of a a particular element. For each isotope the atomic mass is approximately the mass of both protons and neutrons since electrons make minor contributions.
The atomic mass of Gold (Au) is 196.9665 but, it can be rounded to 197.
Answer:
Put soil water many plants and a few insects in a sealed clear plastic aquarium place it in an area with direct sunlight.
Answer:
If the parents were both carriers.
Explanation:
Since cystic fibrosis is a recessive genetic disorder, two of the same alleles must be present in order to show, so.. for example, the genotype would be cc. The parents without the disorder must've been carriers, and their genotype would be Cc.
If you do a punnet square, Cc x Cc = 25% cc, 50% Cc, and 25% CC.
