Among the more important groups are the diatoms, cyanobacteria, dinoflagellates and coccolithophores.
Phytoplankton, are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis.
<h3>What are Phytoplankton ?</h3>
Phytoplankton is made of very tiny--usually one-celled--plants. Since plants make their own food and release oxygen as a byproduct, all the other living things in the ocean depend on them directly or indirectly for food or oxygen.
- The two main classes of phytoplankton are dinoflagellates and diatoms.
- Dinoflagellates use a whip-like tail, or flagella, to move through the water and their bodies are covered with complex shells.

Answer:
False, I believe. Mutations sometimes might have an effect that helps the population. Example: I've heard of Two-Headed snakes, and even seen some on the internet. They live their lives just fine, so I suppose the mutation was actually quite helpful.
On number two of the second file, mass is how many atoms there are, while weight is how much he gravitational body the object is on (if any) pulls the object (which is why we weigh nothing in space).
For the first question of the second image, A's answer would be 1,800 g/300cm^3, or 600g/cm^3.
For B, .250g/cm^3 * 200cm^3 is 50g.
For the table: Density is how compact the matter of an object is in a certain amount of space. An example would be that water has a density of 1g/cm^3
Mass is how much matter there IS, for example, a car has more mass than an orange.
Volume is the quantity of 3d space an object has or how "big" it is. For example, a cubed building is the length of one side to the third power
Weight is how much gravity is pulling on an object, and not related to how much stuff an object has other than that, for example, you might weigh 100 kilograms on Earth but none is space, and your matter hasn't changed.
I hope you enjoyed your answer.
