Answer:
[ANSWER]
Explanation:
When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.
Answer:
Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.
Explanation:
Phospholipid is a unique form of lipid. The bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.
The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains that retained lipid features are hydrophobic <u>water hating.</u>
Therefore if a phopholipid is placed in water, in relation to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular layer to form an impermeable barrier to hydrophilic (polar) substances.
This forms the basis of the phospholipd bilayer of the cell membrane. And it controls the permeability of the cell membrane to influx substances into the cells.
The answer to this is bioethics.
Bioethics is the ethics of medical and biological research

Bioremediation is the process of using living organisms to detoxify a location. Microbes are used to clean up contaminated soil and groundwater. The organisms that are used in this process are: bacteria, fungi, archaea. For example, b<span>acteria are introduced to the area of the spill where they break down the hydrocarbons of the oil into carbon dioxide;</span>..
