Without it, there are no stars, including our own sun, and there wouldn’t be us talking about it.
It is used in particularly destructive bombs.
At a tiny scale, it can be used to produce neutrons, eg, a Farnsworth Fusor.
At a large scale, we have yet to figure out how to make controlled fusion work in a way that runs for a long time and generates collectible power we can use to feed the process. This has remained elusively 20 years out from the current state of affairs for 50 years.
If it was made to work, then it would probably be a good source of clean energy that would be safer than many of the non-renewable alternatives.
I don’t expect to live to see it happen.
Answer:
4. The suspected causative agent must be isolated from the diseased host and grown in pure culture
Explanation:
Robert Koch (1843-1910) was one of the most important bacteriologists of all time. Famous for discovering the tuberculosis bacillus (precisely on March 24, such as today, in 1882), he also discovered the cholera bacillus and is considered the founder of bacteriology. He worked on the isolation of infectious agents and reinfections from pure cultures, experiences from which he established the "Koch Postulates".
These postulates have been taken as a reference that describes the etiology of all the causative agents of an infectious disease, although they were originally used to describe only the tuberculosis bacillus. They are the following:
1- The agent must be present in each case of the disease and absent in the healthy.
2- The agent should not appear in other diseases.
3- The agent must be isolated in a pure culture from the lesions of the disease.
4- The agent has to cause the disease in an animal that can be inoculated
I think they are good and bad
That's called evolution. I'm not sure exactly what it's asking, but I hope this helps you
Answer:
Bone.
Explanation:
Calcium is one of the important element present in the body. Calcium plays an important role in the muscle contraction. The calcium ions also acts as a signalling molecule during cell signalling.
The calcium is present in our extracellular fluids, bones, and teeth. The major constituent of calcium is present in the bone. The bone consists of around 90% body;s calcium.
Thus, the correct answer is option (b).
