Answer:
Photon radiation
A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).
The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.
Answer:
There are many questions that can be answered by science but I will provide some examples below.
Explanation:
Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.
In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:
Biology
<em>How does climatic phenomena, such as El Niño and La Niña, affect the migration of whales?</em>
<em />
Neuroscience (humans)
<em>Is schizophrenia hereditable?</em>
<em />
Behavioral Ecology
<em>Does climate change affect the capability of cuttlefish to camouflage?</em>
Neuroscience (Animals)
<em>Are killer whales capable of problem-solving?</em>
<em />
Ecology
<em>How does the reduction of apex predator populations (terciary consumers) affect the population of secondary consumers?</em>
<em />
Conservation Biology
<em>Why do increased temperatures lead to coral bleaching? What is the mechanism and how can it be controlled?</em>
<em />
Animal Behavior
<em>What is the mechanism that Ophiocordyceps unilateralis (Zombie fungus) uses to manipulate ants for its own disperal?</em>
<em />
Parasitology
<em>Does the parasite Toxoplasma gondii induce erratic behaviors in humans?</em>
Answer:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
