Answer:
The amphipathic property of the phospholipids that constitute the membrane
Explanation:
It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.
The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.
The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.
This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.
Prokaryotic cells: lack membrane-bound organelles, relatively small - typically less than 10 μm in size.
Both cell types: use ribosomes to synthesize proteins, contain DNA.
Eukaryotic cells: complete copy of DNA stored in multiple chromosomes.
In particular, prokaryotic cells have no nucleus and no membrane-bound organelles, therefore their ribosomes float freely intracellularly. On the other hand, eukaryotic cells have nucleus and membrane-bound organelles. Also, their DNA is bound to proteins and stored in the form of chromosomes in the nucleus.
A species that is habitat specialist and lives at the highest elevation.
Explanation:
An ecosystem consist of plants, animals as well as micro-organisms but due to climate change the plants as well as animals are in danger . The case that has been provided in the question where due to climate change the temperature rises as a result the species living at the highest elevation are in problem .
Due to rise in temperature the snow is melting and the sea water level is rising. The animals and plants adapt themselves according to the climate where they are residing but suddenly if climatic change take place they will be unable to survive.
The animals which are mostly affected due to climatic change are snow leopard, polar bear, giant panda.
