Answer: Autocrine signal, paracrine signal and endocrine signal.
Explanation:
Testosterone is an example of hormone which shows its effect on different locations of the cells.
The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.
Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.
The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.
All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.
The answer is Dilutions
Bacterial culture is one of the laboratory examination that could be used to determine if a specimen contain bacteria. But it will hard to count the colony if the bacteria count is too high.
That is why the specimen of the culture need to be diluted to reduce the bacteria count of the specimen, so the result will be easier to count. The unit used would be colony forming unit(CFU) per milliliter.
A meteorologist would use a radar to follow the path of an approaching thunderstorms
