Cells that have no mitochondria are unable to convert oxygen into energy, found in the form of adenosine triphosphate (ATP). All multicellular eukaryotic organisms, including plants and animals, have mitochondria in some cells, but prokaryotes and some single-cell eukaryotes do not have mitochondria.
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
I would tell the room mate that what i just heard was the resemblance between the Fayum catarrhines and the Miocene proconsulids in skull form and dentition which suggests an evolutionary relationship, even if the direct fossils evidence is not present. Primates are divided into two groups; the prosimians and anthropoids. Monkeys evolved from Prosimians during the Oligocene Epoch while Apes evolved from the Catarrhines in Africa during the Miocene Epoch. Apes are then divided into the lesser apes and the greater apes.
