How much energy does nuclear fusion generate
Pavlova-9 [17]

4. E=mc²

Explanation:

The best approximation of the energy released during a nuclear fusion process can best be determined using the Einstein equation.

  In nuclear reactions, mass and energy are equivalent:

            E = mc²

 E is the energy

  m is the mass

  c is the speed of light

  • In nuclear reactions, some of the mass is converted into the energy.
  • Therefore mass is not conserved in such equations.
  • This is why they release huge amount of energy.
  • From this equation, we know that the more mass loss, the more the energy that would be produced.
  • In a fusion reaction, two light nuclei combines to form a heavier one.

How do humans contribute to natural selection? Help Plz
Montano1993 [528]
We are the top of the food chain, so we hunt a lot. like the way we do the fish in nets, it’s normal now for a fish to be naturally selected to be caught in the fishers’ net. humans contribute by hunting and collecting their own food even if they do it in masses just like how a cheetah catches and eats a gazel.

A patient suffering from breast cancer chooses to undergo surgery. Doctors remove the breast where the tumor is. However, doctor
-Dominant- [34]

Answer:

The correct answers are: A single diseased cell can multiply into a new tumor; cancer cells can travel through the blood and spread into new areas; many cancer cells multiply so fast that new tumors can form.

Explanation:

Cancer is the term that groups different conditions that have all one thing in common: there's an abnormal cell growth that can potentially irradiate to other parts of the body.

A single diseased cell can develop a tumor, because this abnormal cell has the capacity to replicate so fast and, of course, transmit its abnormality to every other cell that it generates.

These abnormalities occur because there is some sort of damage in the DNA of a cell, which most of the time is detected by the body and eliminated - but when it's not, the cell quickly multiplies itself and generates a tumor. The difference between a benign tumor and cancer is that cancer can spread through the body and a benign tumor can not.

Cancer is very dangerous and potentially fatal if not treated fast because it can travel through the bloodstream or the lymphatic system and invade other organs, causing metastasis.

There's a lot of research being done on how to cure cancer, but the disparities in every different type of cancer make finding the solution much harder. Nowadays, depending on the type of cancer and the stage where the cancer is, this condition can be treated with radiotherapy, chemotherapy, or surgery.
