The conditions mentioned are both a type of sclerosis, which refers to the hardening of a certain anatomical feature.
In atherosclerosis, the affected <u>anatomical feature </u>is the artery. This is a condition that causes the <u>obstructions </u>of <u>blood flow </u>through the artery as a result of plaque buildup along the artery walls. Unlike with MS, atherosclerosis does not present symptoms until the obstructions are severe or the plaque loosens, which can lead to <em>heart attacks</em>, among other consequences.
In the case of Multiple Sclerosis, the affected anatomical structure is that of the nerve. This is a condition for unknown reasons, causes the <u>immune system </u>to attack the myelin covers of nerve cells which act to protect the cell. The absence of this cover causes the build-up of plaque along the nerve axon, <u>stiffening </u>and <u>disrupting </u>the communication of the nerves with the central nervous system.

The compatibility of a person’s temperament with his surrounding environment is referred to as “goodness of fit.”Some temperaments and environments seem to naturally fit together, while others do not.There are two types of “Goodness of Fit:”how that trait interacts with the environment how it interacts with the people in that environment.Any trait in and of itself is not a problem; rather, it is the interaction that determines the “acceptability” of that trait.
The right answer is the promoter.
• The promoter is a nucleotide sequence that allows the transcription of the gene into mRNA. It is recognized by the RNA polymerase that initiates transcription. During the synthesis of the RNA, the promoter indicates which gene must be expressed and therefore which proteins the cell must produce. In an operon it is common to all genes.
• The operator is a segment of DNA and / or messenger RNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon. The RNA polymerase does not recognize this structure.
Answer:
What is the difference between microevolution and macroevolution? Microevolution deals with changes in the gene pool of a single population. Macroevolution considers the broad pattern of evolutionary change over long periods of time and includes the origin of new groups.
