Is it possible to determine the sex of a cell donor by examining the cell?
Yes, by examining the DNA of the cell, you will be able to determine if the donor was male (XY) or female (XX) based on the sex chromosomes. You will not be able to determine the sex of the donor by the appearance of the cell - the only way is to determine what sex chromosomes are present. Unless the cell is a sex cell, in which case sperm cells are easily distinguished from ovum/eggs.
How can an ecologist predict the size of a population without counting every organism in the population?
Through mark-and-recapture projects, direct observations, or targeted sampling, ecologists are able to determine the population of a particular species. This process is a scientific estimation of the population.

How do you measure the temperature on the sun?
Doppler shifted lines. by examining spectrographs of the sun, we can determine, via use of dopper shift, and examining the color of the sun, i.e. yellow, this correlates on a scale of light/heat as roughly 6000 on the Kelvin Scale. if the Sun were blue, we would be able to deduce that the sun was roughly 7500 K. For further info, look up the Kelvin Scale.
