Like with living primates, we are able to definitively distinguish catarrhines from platyrrhines in the fossil record by what fe
Kazeer [188]

Answer:

The structure of their noses.

Explanation:

Catarrhines are distinguished from platyrrhines by several traits but the main distinctive feature between them, is the structure of their noses. This forms the basis of their names.

Platyrrhines are characterized by laterally-placed, rounded nostrils or flat-nosed while catarrhines have narrow, downward-facing nostrils or hooked-nosed.

Another distinguishing feature include their dental formulation which is 2.1.2.3 in catarrhines and 2.1.3.3 in platyrrhines.

How does the movement of materials across the cell membrane relate to an<br> organism’s survival?
ioda

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening
