Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.

Answer:
Breathing is a physical process that involves various organs like the lungs, windpipe, nose, and others for exchanging the gases that are inhalation or taking of oxygen and expelling the carbon dioxide in the body.
Respiration is a chemical process that takes place inside of the cell by breaking the sugar using oxygen taking from breathing to produce energy. These both processes are different, however, interrelated to one another as breathing provides oxygen for respiration, and respiration gives up carbon dioxide to expel out by breathing.
A:acquiring energy
B:homeostasis
C:maintaining its structure
D:reproduction
Answer:reproduction
Answer:
The correct answers are: A single diseased cell can multiply into a new tumor; cancer cells can travel through the blood and spread into new areas; many cancer cells multiply so fast that new tumors can form.
Explanation:
Cancer is the term that groups different conditions that have all one thing in common: there's an abnormal cell growth that can potentially irradiate to other parts of the body.
A single diseased cell can develop a tumor, because this abnormal cell has the capacity to replicate so fast and, of course, transmit its abnormality to every other cell that it generates.
These abnormalities occur because there is some sort of damage in the DNA of a cell, which most of the time is detected by the body and eliminated - but when it's not, the cell quickly multiplies itself and generates a tumor. The difference between a benign tumor and cancer is that cancer can spread through the body and a benign tumor can not.
Cancer is very dangerous and potentially fatal if not treated fast because it can travel through the bloodstream or the lymphatic system and invade other organs, causing metastasis.
There's a lot of research being done on how to cure cancer, but the disparities in every different type of cancer make finding the solution much harder. Nowadays, depending on the type of cancer and the stage where the cancer is, this condition can be treated with radiotherapy, chemotherapy, or surgery.
