Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.

Yes a false positive result will be read
Explanation:
Instructions on most pregnancy tests will tell you to read the results in a certain amount of time, usually from a couple of minutes. So you may take a pregnancy test and read it within the above time period as negative.

What is Evaporation Lines?
Evaporation lines happen when the urine that was on the test area starts to dry out and evaporate. The chemical composition of that particular urine sample has now changed since that urine sample evaporated, sometimes causing the test to show a positive line
