Photosynthesis is the process.
Hey there!
Your question states: <span> Explain why cells are so small, considering the relationship between surface area and volume for objects of different sizes but similar shapes.
Cell's are small because the size of the other surface area's and also there volume would obviously be bigger than the cell it self. So, they are basically bigger based on that it</span><span> is the most efficient at their </span><span>size. Cell's can not be big and there on some one's hat, that would be very weird. This would be why cell's are the size that they are.</span>
I want to say arthropods and flatworms. I am pretty sure that the others you cannot see the segmentation
Answer:
2)They have similarities in their embryonic stages that don’t exist in their adult forms
4)They all contain a backbone, or spinal column
Explanation:
In the embryonic development of vertebrates during the early stages of development there are great similarities. Vertebrates in the early stages as shown in the image are very similar and subsequently develop the structures of their own species that differentiate them.
The presence of notocorde is a characteristic characteristic of vertebrates and birds, fish, reptile amphibians and mammals have it since they are embryos to adults
