You did not provide options therefor i can not be exact but the cell membrane and cell walls are what contain the cytoplazm so it would not be ar
part of it
No.
This method of stating population density is carried out by counting the number of specimen in a given area and then dividing the number of specimen by that area. This does not mean that each specimen is one meter apart. Some regions may have no specimens for multiple meters while other regions may have multiple specimen in the same meter. The population density gives us an average value.
Answer:
Based on their body <u>structure</u><u>,</u> flatworms and rotifers were not thought to be closely related. However, <u>bilateral symmetry and body texture</u><u> </u>showed that they are a <u>soft-bodied</u> group.
Explanation:
- Flatworm belongs to phylum Platyhelminthes and Rotifera belongs to phylum Rotifera.
- Their body structure may be different but both of them have a bilaterally symmetrical body.
- Both are aquatic animals.
- Flatworm is made up of ectoderm endoderm and mesoderm and has circular and longitudinal muscles. Rotifera is made up of skeletal and visceral muscles. So, they are soft-bodied animals.
From this, you hypothesize that this lineage of dinoflagellates was the result of ENDOSYMBIOSIS. It benefits both organisms.
<h3>What is endosymbiosis?</h3>
Endosymbiosis is an ecological relationship where one organism is incorporated inside another and it benefits both.
The theory of endosymbiosis states the eukaryotic cells emerged via this type of relationship.
According to the theory of endosymbiosis, prokaryotic organisms that were introduced into primitive eukaryotic cells led to the formation of chloroplasts and mitochondria.
