Answer:
There is no short answer.
Explanation:
Gravitational attraction depends on two factors, the mass of the objects and the distance between them.
In the example given in the question, the gravitational attraction to the moon would be much higher than the gravitational attraction to the cat because of the big mass difference between them even though the cat is closer to Tina.
I hope this answer helps.
Answer:
The given statement is False.
Explanation:
During the prophase stage of mitotis, the chromatin starts becoming more condense. Histone protein is a basic protein which is responsible for initial and basic packaging of chromatin into nucleosome.
The second level of chromatin packaging occurs when the nucleosomes are arranged in the fiber which has a diameter of about 30nm. Each nucleosome is attached with H1 histone and nucleosome fiber coil to form a solenoid structure which has a diameter of 30nm. Therefore the statement is false.
Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere.
Answer:
Average speed = total distance / total time
= 68 / 1 5/12 [ change 1 5/12 to an improper fraction - 17/12]
= 68 / 17/12 [perform division]
= 68 * 12/17
= 48 miles per hour
