The answer is b. nematocyst. (hope this helps!)
The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.
Explanation:
In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.
This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.
Answer:
The division of eukaryotic cell is done through various phase known as cell cycle.
Explanation:
The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:
1) G2 Phase; G2 checkpoint ( Interphase stage)
2) Prometaphase (Mitotic Phase)
3) Anaphase (Mitotic Phase)
4) Telophase (Mitotic Phase)
5) cytokinesis (Mitotic Phase)
6) G1 Phase; G1 checkpoint ( Interphase stage)
After G1 phase there would be again S phase in which DNA replication occur.
I had the same question and the answer was C OR A.
I believe it’s an active dye?
