Answer: The answer is Israel.
Answer:
Lobster
Explanation:
Lobster was also known as the poor man's meal because the overabundance of these guys made it easy for people with no money to get their protein. In fact, these crustaceans were fed to prisoners, apprentices and slaves.
Latitude.
It is measured with 180 degrees imaginary lines that form circles around the Earth east west, parallel to the Equator. These lines are known as parallels.
Answer:
It was a list of grievances against the king of England intended to justify separation from British rule. The Constitution was written and signed in 1787. It was a charter of government that came to be ratified by the states, and it continues to be the supreme law of the land.
Answer:
B and C
Explanation:
B. In a given rock sample, the amount of Silicon-32 isotopes gets divided in half about every 170yrs.
This is the concept of half-life. Half life is the time take for half of a radioactive isotope to disintegrate. The shorter the half life the faster the isotope disintegrates.
From the question, we were told that it would take 170yrs for half of the isotope of Silicon to disintegrate to Phosphorus. This is the half life.
C. The half life can be used to determine the amount of Si-32 that has decayed from the time closure temperature was reached.
The closure temperature is very important in radioactivity. It is the temperature at which a system has cooled and there is no resulting disintegration of parent and daughter isotopes.
From first order kinetics, we know that the rate at which radioactive elements decay at any time is directly proportional to the number of radioactive atoms present. A knowledge of the half life helps to figure out the number of atoms that has decayed in time.
