By understanding how cancer cells differ from normal cells, researchers develop treatments. If you have cancer, this knowledge may help you understand what’s going on inside your body.
These are the most significant differences between cancer cells and normal cells:
Cancer cells keep dividing. Cancer cells ignore the body’s signals to stop dividing. Your body has a built-in process, called apoptosis or programmed cell death, that tells the body to get rid of cells it doesn’t need anymore. Normal cells are better at listening: They listen to the body’s cues and stop reproducing when enough cells are present.
Cancer cells grow too rapidly to mature. Normal cells mature into distinct cell types. These different cell types have specific functions. For example, liver cells help your body metabolize proteins, fats and carbohydrates and help remove alcohol in your blood. Cancerous cells divide so quickly that they don’t have a chance to mature and become the specialized cells they set out to be.
Cancer cells may influence normal cells. Cancer cells may actually affect the behavior of the normal cells, molecules and blood vessels near a tumor. For example, cancer cells may recruit normal cells to develop new blood vessels. These vessels keep the tumor alive—and give it a chance to grow—by providing it with oxygen and nutrients.
Cancer cells trick the immune system. You probably know your immune system helps you fight off infection and disease. The immune system typically gets rid of abnormal or damaged cells. Cancer cells manage to evade this process, which allows tumors to grow.
Cancer cells are invasive. Because cancer cells ignore the body’s signals to stop dividing, they start invading tissues nearby. If a tumor is benign, it may push up against neighboring tissues, but won’t invade it. However, a malignant tumor invades tissue and is capable of spreading throughout the body.
Cancer cells may spread to other parts of the body. Normal cells know their place in your body and stay put. Metastatic cancer cells start spreading to other parts of the body. For example, cancer may develop in the lungs and spread to the liver. If this spread occurs, it’s known as metastatic lung cancer, not liver cancer.
I’m sorry I did way more than one lol.
B. To protect ownership of a new technology
Answer:
A
Explanation:
They form in mountains and flow through mountain river valleys. Glaciers cause erosion by plucking and abrasion.
Answer:
when we obtain a 1: 1 ratio, in which the population is based on plants "Yy" and "yy", it is expected that the allele Y will predominate in number with each generation, in this way it can be predicted that the frequency would change to be of plants "YY" to 90% and 10% of plants "yy", a process called natural selection, so plants with many flowers and leaves will prevail, as well as the highest, becoming a cycle in which the Y allele, due to its characteristics, will become more competitive and successful to reproduce.

CRISPR Used To Edit Genes Inside A Patient With A Rare Form Of Blindness
and what CRISPR is is s a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea.[2] These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. Hence these sequences play a key role in the antiviral (i.e. anti-phage) defense system of prokaryotes.[2]

The CRISPR-Cas system is a prokaryotic immune system that confers resistance to foreign genetic elements such as those present within plasmids and phages[4][5][6] and provides a form of acquired immunity. RNA harboring the spacer sequence helps Cas (CRISPR-associated) proteins recognize and cut foreign pathogenic DNA. Other RNA-guided Cas proteins cut foreign RNA.[7] CRISPR are found in approximately 50% of sequenced bacterial genomes and nearly 90% of sequenced archaea.
