According to the food chain below, which of these organisms most likely contains the least concentration of toxins (DDT) ?
agasfer [191]

Answer:

Hawk

Explanation:

Dichlorodiphenyltrichloroethan which is also known as DDT is a colorless, tasteless and almost odorless crystalline chemical compound. It was originally developed as an insecticide and it causes harm to wildlife animals.

When the chemical are sprayed or gets in contact with the soil it is the terrestrial organisms such as plants and primary consumers who gets affected the most due to direct contact with the chemical.

Animals such as hawks who are arboreal and tertiary consumers from the list of options don’t get affected directly from the source of the DDT contamination which makes them least affected.

Some interphase cells contain twice as much DNA as other interphase cells within the same tissue sample. Is this normal? Why?
FinnZ [79.3K]

Answer:

Yes, Since the interphase cells in G2 would have twice the DNA as the interphase cells in G1 phase or start of S phase.

Explanation:

Interphase has three stages: G1, S and G2 phase. DNA replication occurs in the S phase and doubles the DNA content of the cell. So, the DNA content of the interphase cells of the same tissue depends on stages of interphase.  

The interphase cells which are in the G1 phase has half the DNA content as it is present in the interphase that has entered the G2 phase after completion of DNA replication in S phase.
