Answer:

Explanation:
An element only has <u>one</u> type of atom and cannot be broken down by chemical means.
Let's analyze the answer choices.
1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.
2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.
3. This has one type of atoms, so it is an element.
Therefore the best answer choice is 3.
It is the sun. You start with photosynthesis.
Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. Comparison chart Embed this chart Nuclear Fission, Nuclear Fission is the splitting of a large atom into two or more smaller ones. Fusion is the fusing of two or more lighter atoms into a larger one. Natural occurrence of the process: Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun. Byproducts of the reaction: Fission produces many highly radioactive particles. Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that. Conditions: Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is
Answer:
Microorganisms can be found both in the external environment (ecosystem) and the internal environment (microflora) of higher organisms.
Explanation:
Microorganisms (microbes) are microscopic forms of life that include bacteria, protists, fungi and animal species, these organisms can se differentiated by using laboratory techniques such as the Polymerase Chain Reaction (PCR) or by microscopes. These organisms are both beneficial and both beneficial and pathogenic for humans. For example, the microflora may be useful in digesting nutrients contained in the food. On the other hand, <em>Plasmodium falciparum</em> is a pathogen microorganism that is found in the digestive system of mosquitoes and cause malaria in humans.
Answer:
With gravitational potential energy, the farther the object is from the ground, the greater the potential energy would be.
