(ANSWER CHOICES)
Explanation:
Answer:
B. The cell membrane surrounds particles outside the cell.
Explanation:
The last step is when the cell membrane completely surrounds particles outside the cell.
This process is often known as endocytosis.
- endocytosis is the process whereby a cell ingests materials by engulfing them using the cell membrane.
- In this process, the cell membrane completely covers the food.
24.305 g +28.08 g + 3(15.999 g)=100.382
219 g MgSIO3 (1 mole MGSIO3/100.382g)=2.181 mol MgSIO3
the answer is 2.18 mol MgSIO3
This question is more for Biology than Chemistry, but the role of producers is to make energy (food) to be consumed. In a pyramid diagram, the producers would be at the bottom. Now going up the pyramid, the primary conumers are the first to consume producers and obtain energy from them. As you go up the pyramid, the secondary consumers will consume the primary consumers as a way to obtain energy, and the same goes for tertiary consumers towards secondaries.
As you go up the energy pyramid, you will notice a trend that there is less energy being obtained from each consumer. In other words, the producers will ALWAYS have more energy than the tertiary consumers.
I hope this answers your question.
