Answer: The killer is C; Karen

Explanation:

After looking at the birdbaths results and Karen's results, you can see that they are the same. This will make Karen the killer. Since the killer washed their hands in the birdbath, the detectives were able to get trace amounts of DNA.

DNA fingerprints are determined by a chemical test. This takes the persons genetic makeup and matches it with other peoples that are in a database. This type of DNA testing can be used in courts, identify bodies, find cures, and also look for missing people.

Which of the following statements about plankton or nekton is NOT correct?
Oduvanchick [21]

Answer:

C. All plankton are closely related to plants.

Explanation:

Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.

Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.

Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.

Nekton are organisms found in water that swim actively.

Based on this information, we can conclude that statement C is the only incorrect statement.
