Explain how knowing the half-life o carbon 14 can tell scientists the absolute age of a rock sample

1 answer:

4 0

Carbon 14 has a half life of 5,730 years. Scientists measure how much carbon 14 the rock has. For objects older than 50,000 years, scientists will test the age of the things surrounding it.

Which of the following statements best describes what happens when a bacterial cell is placed in a solution containing 5 percent

lora16 [44]

Answer:

C) Water will move out of the cell.

Explanation:

In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.

This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.

A model shows that the moon has grown to twice its size, yet it has remained in the same place. In one to two sentences, explain

professor190 [17]

Answer:

If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much

Explanation:

The force of gravity between two objects is doubled if the mass of one of the objects is doubled.

If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much, since the gravitational force is proportional to the masses of both the Earth and the Moon.
