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. ...
Hormone therapy. ...
Targeted drug therapy. ...
Cryoablation.

3. An animal population decreases from 800 individuals to 600 individuals. Which of the following could explain this
change in population size?
A. The population size of the animal's predator increased.
B. The emigration rate of the animals from the population decreased.
C. The population size of the animal's prey increased.
D. The number of species competing with the animal for food decreased.
RESOURCE:
ASAP
The statement that could explain the reason for the decrease in population of an animal from 800 individuals to 600 individuals is: The population size of the animal's predator increased.
POPULATION:Population refers to a collection or assemblage of individuals of a species of organism. A population decrease means loss of individuals of a species.
Population decrease can be attributed to the following reasons:
Increase in the number of predators of that species. Emigration i.e. moving outIncrease in competition within the populationThis means that a population decrease in the animal in this question could be caused by an increase in the population of predators.

When would a point mutation occur?
It can occur before and after cell division
Before the cell divides
After the cell divides
Before DNA replication
Answer:
The correct answer is option 1. Before and After Cell Division
Explanation:
Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations. But they may also occur after as well as before the division of a cell.
How do scientists identify organisms that may have disease resistance genes?
Answer:
The use of genetic engineering in developing disease-resistant plants. The techniques of genetic engineering can be used to manipulate the genetic material of a cell in order to produce a new characteristic in an organism.

Answer:
I think it's A) A protein substrate
This instrument has made it possible for scientists to observe certain objects and processes that would otherwise never have been seen with the naked eye or a common magnifying glass, because they are more stable and can be built with greater magnifying power, so that smaller structures can be seen and studied. It is used in a wide range of scientific fields, and has contributed to major discoveries in biology, medicine and materials research. What is the instrument?
Answer:
The modern field of biomaterials combines medicine, biology, physics, and chemistry, and more recent influences from tissue engineering and materials science.
Explanation:
The answer is microscope.

which is the primary advantage to sexual reproduction over asexual reproduction?
Answer:
Sexual reproduction is typically advantageous over asexual reproduction because the environment is constantly changing. Sexual reproduction allows new combinations of genes to form. This greater genetic diversity increases the phenotypic variation: that is, it increases the physical variety of the organisms.

Check the statements below that provide evidence for the endosymbiosis theory
The DNA in the nucleus and mitochondria are the same.
This is not exactly true, although they are similar. This is not a correct option.
The following three are correct options:
Mitochondria and chloroplasts grow independently from the cell.
This is true, and supports the idea that they previously existed as their own organisms.
Prokaryotic cells, mitochondria, and chloroplasts are all the same size.
All three organisms/organelles are roughly the same size, which supports the idea that chloroplasts and mitochondria are descendants or prokaryotes.
Mitochondria and chloroplasts contain their own ribosomes.This is true as well.
