Mr. rojas was looking through a microscope at some similar cells. he noticed that every cell had a different structure. what can he infer about these cells? * they are from different organisms. they have the same organelles. they have the same functions. they have different functions.

They have different functions

Explanation:

Every cell has different functions since they all look different. A cell cannot have a different structure and have the same function though

They have different functions.

Explanation:

The cells having different structures may come from the same organism and having different structures may result from having different organelles. Due to the structure function correlation in cells, it is thus likely that the different structures arise from different functions, hence cells are specialised structurally to optimise performance in their functions.

answer: A chemical test for starch is to add iodine solution (yellow/brown) and look for a colour change. In the presence of starch, iodine turns a blue/black colour. ... For example, if iodine is added to a peeled potato then it will turn black.
