I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
It is called Fluid Mosaic Model. It describes the structure of the plasma membrane as a mosaic component. The structures such as phospholipids, protein, carbohydrates and cholesterol gives the fluid like character of the plasma membrane.
Answer:
Option A, a compound that contains carbon atoms bound to other elements
Explanation:
An organic compound is one which has at least one carbon atom that is bonded to several other atoms (may be metallic or non metallic) by a single or double bond is termed as organic compound . The most common atoms with which carbon forms bond are hydrogen, nitrogen,and oxygen.
Some common examples are -
Methane - 
Methanol - 
Hence, option A is correct
The correct answer should be Sensory Neurons, also known as afferent neurons. They <span>transport information to the integrating center.</span>
Hi There!
Question - Explain the cellular functions that occur when antibiotics attack a bacteria cell.
Answer - When bacteria grows to a certain limit it will not be able to divide or spread any further. (Transportation is trough the blood). The purpose of antibiotics in this case is to stop any further growth ot spreading from causing any harm to the body. In cellular functions the antibiotics used will ruin the DNA of the bacteria which will stop the growth.
Hope This Helps :)
