Which of these is NOT characteristic of chordates?

Biology

Leya [2.2K]2 years ago

The option which is not a characteristic of chordates is chloroplasts in their cells.
Chordates do have a dorsal supporting rod (vertebrates are types of chordates - they have a spine), a dorsal hollow nerve cord (within the spine), and pharyngeal pouches. However, they do not have chloroplasts, because that is a characteristic of photoautothropic eukaryotes, which chordates certainly are not.

What type of solution is this cell sitting in?
Dafna1 [17]

Answer:

The correct option is A. The cell is sitting in a hypertonic solution.

Explanation:

A hypertonic solution is a solution in which there are more number of solutes present in the solution than inside the cell. The solutes then tend to pass into the cell through diffusion from the solution.

As it can be seen in the diagram, the concentration of salt is more in the solution i.e 40%. Hence, the salt from the solution enters into the cell by diffusion and has a concentration of 10% inside the cell which shows the cell to be placed in a hypertonic environment.
