Answer:
Explanation:
Bilateral symmetry is a type of body symmetry where the body is divided in to halves i.e refers to organisms that have body shapes which look like mirror images along the midline which is called the sagittal plane.
Hypoventilation is a process where little amount of air enter into the alveoli which result in a decrease in the amount of oxygen in the lungs and increase in carbondioxide produced by the lungs. It is caused by too shallow breathing or slow breathing.
Hemothorax is a condition where there is blood build up in the pleural space or chest wall and lungs.
Arrhythmias is a health condition where there is irregular heartbeat. That is the heart may beat to fast, too slow, or irregular heart rhythm.
The purpose of the replication bubble is that it forms where replication is taking place (option A).
<h3>What is replication?</h3>
Replication is the process of producing replicas or duplicate of DNA or RNA molecules.
DNA replication is a very important process that occurs prior to cell division. During replication, the double stranded DNA is separated into two single strands.
Each copy called the leading and lagging strand becomes the template for the synthesis of new DNA strands.
However, a structure called replication bubble is a formed during the separation of two DNA strands by the helicase enzymes.
Therefore, the purpose of the replication bubble is that it forms where replication is taking place.

Answer:
cell membrane
Explanation:
The cell membrane in the diagram consists of lipids, bilayers, and proteins. The lipids, located within the cell membrane, are known as hydrophobic, meaning they are afraid of water. In other words, the lipids keep out the water. Whereas the bilayer, otherwise known as the phospholipid bilayer, is attracted to water. While the proteins simply enable molecules and other microscopic parts travel within and out the cell membrane, through the protein.
Answer:
C. Stabilizing selection
Explanation:
Natural selection, is of three different types namely: disruptive selection, directional selection and stabilizing selection. Disruptive selection occurs when the two extremes of a population are being favored over the average or intermediate.
Directional occurs when one extreme of a population is favored. However, in STABILIZING SELECTION, the average or intermediate population is favored over both extremes of a population. Example is when the average-sized beaks of a bird population is being favored over the long and short ones (extremes).
