Answer:
M phase
Explanation:
While there are many checkpoints within the cell cycle, the specific checkpoint you are referring to most likely takes place in the M (mitosis) phase.
Before the M phase (which includes the G1, S, and G2 phases), the cell grows, the number of organelles increases, and DNA replicates. After the G2 phase, the M phase begins. At the beginning of this phase, the DNA condenses, lines up in the center of the cell, attaches to spindle fibers, and is pulled to opposite ends of the cell. If this checkpoint receives the proper signal, the actual division of the cell will occur.
Answer:
A student can measure the number of gas bubbles given off by the algae.
Explanation:
- Photosynthesis is the process where green plants convert light energy into the fuel energy for their development and activities.
- Algae is also involved in the photosynthesis process, so the it releases the gas bubbles.
- The oxygen emission process is done by secreting the bubbles by green plants during photosynthesis process.
- So to know about the photosynthesis rate the number gas bubbles, really helps a lot.
I would say photosynthetic bacteria are the most important, because if they disappeared most of the oxygen in the atmosphere wouldnt be here and complex life like humans wouldnt exist
Well for the very last sentence it would be if any of the organs shut down it could seriously hurt someone or possibly even kill them if their brain,heart or some other important organ shuts down it could kill them.
There are other minor organs where if it shuts down it wouldn't really hurt the person too much. Sorry I couldn't help you with the other ones though.
