Answer:
The answer is DNA replication and crossing over.
Explanation:
Both meiosis and mitosis are reproduction processes taking place in humans. But there is some difference between these two processes. In meiosis, parent cell produces four daughter cells which are not identical to each other.
In meiosis, when DNA replicates it produces four haploid daughter cells in which the number of chromosomes in half. Moreover crossing over and separation of chromosomes also occurs to produce sperms and egg cells. While in mitosis crossing over and DNA replication is absent.
Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.
<h2>The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.</h2>
Transporting blood under high pressure can be explained in the following steps:
- Contraction of the heart ventricles creates blood under high pressure
- High pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elastic
- The lumen of the arteries is narrow thus helping in maintaining high pressure
As a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.

The production of egg and sperm cells follows a certain sequence of events.
The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.
Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.
Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.
Answer B: RNA has Uracil, DNA has Thymine
B. The temperature of alcohol increases more slowly than water when they are equally heated.
Explanation:
Based on the information provided only, we can infer that the temperature of alcohol will increase more slowly than water when they are equally heat. Also, when left to cool, water will cool faster than the alcohol.
Specific heat is the amount of heat required to raise the temperature of 1g of a substance by 1°C.
- A substance with a high specific heat will require more heat to raise the overall temperature.
- A substance with a low specific heat requires little heat to cause appreciable temperature changes.
- Metals for example have low specific heat that is why they get hot very fast when heated and cools very fast too.
