What are the challenges of treating or curing cancer?
Answers
Answer:
- Cancer isn't a single disease. The term cancer encompasses more than 200 diseases all characterized by the uncontrolled proliferation of cells.
- Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division 5start superscript, 5, end superscript.
Genetic Changes and Cancer
Genes carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls and become cancer. For example, some cancer-causing gene changes increase production of a protein that makes cells grow.
- People who have certain jobs such as; painting, construction, pesticide and petroleum workers have an increased risk of cancer. Many studies have shown that exposure to asbestos, benzene, benzidine, cadmium, nickel, arsenic, radon and vinyl chloride in the workplace can cause cancer.
- Metastatic cancer causes most cancer deaths, but exactly why it is so difficult to treat is not precisely understood. Metastatic tumors often acquire additional genetic changes from those in the primary tumors that spawned them, and these genetic characteristics may cause them to resist standard treatments.
- Treating cancer is further complicated due to the lifestyle and attitude of patients, the different physiology of people and the rate their bodies will metabolise drugs, the blood supply to the tumour affecting the drug getting into the tumour, the tumour physiology and the fact that the tumour can continue to change.
- The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells.
- Cancer treatment options include:
Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.
Chemotherapy. Chemotherapy uses drugs to kill cancer cells.
Radiation therapy. ...
Bone marrow transplant. ...
Immunotherapy. ...

Which ratio of surface area to volume is most efficient for a cell?
Answers
Answer:
Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

a particular peach tree produces peaches that are more resistant to disease than other peaches. what method would reproduce these exact peaches?
Answers
The best way to get the exact preach tree is through Asexual reproduction.
Asexual reproduction is the only method of reproduction in which the exact copies of genes in the parents are transferred to the offspring. If cross pollinations( Sexual reproduction') with the a peaches plants from a different parents plants takes place, genetic variation at meiosis will not permit the inheritance of the exact copies of genes for diseases resistance.
Therefore, it is ideal in this scenario to by pass crossing over and recombination at meiosis, in order get the exact copes of genes for disease resistance through mitosis in the offspring, asexual preproduction is used.
For more on asexual reproduction; https://brainly.com/question/4100787
The method that would produce peaches of exactly the same characteristics would be cloning or vegetative propagation.
Cloning the peaches that are more resistant to disease will result in the production of peaches with exactly the same morphological and genetic attributes.
The same result would be obtained by propagating the desired peaches asexually using relevant means.

Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response. NO PLAGIARISM WILL BE REPORTED IF SO.
Answers
Viral infections cause similar symptoms as bacterial infections. Antibiotics treat bacterial infections but do not treat viral infections. Some antiviral medicines are used to treat viral infections.
The misuse of antibiotics to treat a viral infection contributes to antibiotic resistance.
Antibiotics kill bacteria without damaging the body’s cells. They do so by interfering with how bacteria live and reproduce. Normal body cells work in different ways, so they’re not affected.
While antibiotics are effective in treating bacterial infections, they can also damage the immune system when used incorrectly or too frequently. Therefore, the doctor should prescribe antibiotics only when needed and sparingly.

Explanation:
Tanya planted seedlings in her garden over the weekend. The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart. Tanya has a measuring tape that has values in centimeters. As we know 1 meter = 100 centimeters . Therefore, 0.2 meter = 0.2 × 100 = 20 centimeters. So Tanya need to be planted 20 centimeters apart.

How could the changes made to the amino acid sequence influence phenotype changes?
Answers
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Protein structure ordersThe sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.

Yifei and Santos are making a diorama on the ecological role of organisms. Yifei wants to show the omnivores eating both plants and other animals, and the herbivores eating other animals. Santos wants to show the omnivores eating only other animals, and the herbivores eating both plants and animals. Who is right?
Answers
Answer:
None of them are correct because omnivores, from the root word "Omni" meaning "all", means omnivores eat both plants and animals. Then, herbivores only eat herbs, meaning plants, so both of them are wrong. Animals that eat other animals but not plants are called carnivores.

if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?
Answers
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
expand the equation;
x² - 40x + 400 = x² - 20
collect similar terms together;
x² - x² - 40x = -20 - 400
-40x = -420
[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]
Thus, the value of the unknown number is 10.5.
