Answer:
karyotype is an individual's collection of chromosomes
Explanation:
The term also refers to a laboratory technique that produces an image of an individual's chromosomes.
Answer:
They are orbiting earth.So they stay in orbit.
We know that gravity increases with height.
Explanation:
1st Question Explanation:
- Earth's gravity still pull on them.
- Gravity combines with the satellite's momentum from its launch into space.This Combination cause the satellite go into the orbit.
2nd Question Explanation:
- Gravity is caused by the Earth's spinning
- Gravity is notable bless on high mountains or tall buildings.
The object in the lower orbit will move faster in its orbit, and will have a shorter orbital period. None of that depends on their masses either.
Answer: A cold front occurs when a cold air mass advances into a region occupied by a warm air mass. If the boundary between the cold and warm air masses doesn't move, it is called a stationary front.
Explanation: Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.
