Answer:
The statements that describe how the trans bilayer asymmetry in the lipid bilayer is achieved and maintained are listed below.
Explanation:
Phospholipids in the plasma membrane are anchored to a specific location in the plasma membrane via strong hydrophobic interactions with neighbouring lipids thus maintaining the asymmetrical distribution of lipids in the bilayer.
Specific phospholipids in the plasma membrane covalently attach to certain integral membrane proteins.These covalent interaction anchor the phospholipid to specific location in the plasma membrane and maintain the asymmetrical distribution of lipids in the bilayer.
The cost-benefit analysis done to investigate a proposed mine site would take into consideration the cost of environmental restoration after mining and the value of the ore to be extracted from the mine.
<h3>Cost-benefit analysis</h3>
This is an analysis done to assess the cost and benefits of actions.
For an action to be profitable, the benefits must be more than the cost.
In this case, for a mine site, the value of the ore to be extracted from the mine has to be more than the cost of having to restore the site after mining.
Every other cost can also come in but the two major ones are those highlighted.

<span>Molecular clock is a scale which uses a technique whereby evolutionary time for different life forms is deduced from the mutation rate of biomolecules. Biomolecular data used for calculations in order to come up with the prehistoric time scale normally uses nucleotide sequences for DNA or amino acid sequences for proteins.
Hence, in order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.</span>
