Why is a longitudinal study better than a cross-sectional study for examining how many years cancer survivors stay in remission?

<span>A cross-sectional study examines all of the participants at one time. So for a cross-sectional study of cancer survivors, we would gather some sample of former patients and find out how long they have been in remission.

The problem with that cross-sectional design is we would be missing the people whose cancer had returned and caused them to die before our experiment started; we would have introduced a problem called "survivor bias" by only counting people who were STILL in remission and still alive.

A better experiment will use a longitudinal design of enrolling people whose cancer has just gone into remission, and following them to see how long they stay healthy.</span>

Warmer ocean surface water would most likely be found near ___.
KiRa [710]

The warm ocean water is usually found near the top surface of the ocean. The sun makes the surface of the ocean warm and thus heat up its water. This heat is later mixed by the winds and sea waves from top to beneath the ocean surface. The temperature of the surface is usually warmer than the water at depths as it does not receive sun light. The average ocean temperature at the surface is 17 degree Celsius while at greater depth the temperature falls down to 0 to (-3) degree Celsius

Nonamiya [84]

Answer:

tt

Explanation:

Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.

tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.

So it would make sense that tt is the choice.
