The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
Answer:
the answer is option (a).3
Answer:
Below!
Explanation:
Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.
Hope this helps ya! Best of luck <3
Unlike humans, termites are able to extract energy from wood because: they have some microorganisms living in their gut that are able to break down cellulose.
<h2>Removal of coral and fish will cause a great threat to the ocean ecosystem
.</h2>
Explanation:
- Biodiversity of the marine ecosystem will be markedly reduced
- Marine food web will be affected leading to scarcity of food at each level
- Mean trophic level of the ecosystem will be affected
- The ocean chemistry will be changed
- Habitat destruction of fishes which will affect other aquatic organisms living in the ocean
- Increases ocean acidification and ocean carbon concentration
- The animals interdependent on ocean ecosystem for food like some seal, walrus, and sea birds are affected due to scarcity of food through fishes
- Corals are filter feeders and removing them will lead to eutrophication of coastal waters which in turn leads to algal bloom
- Algal bloom leads to depletion of the ocean’s oxygen level
- Corals are natural barriers and provide natural protection to shorelines and coastal landforms, removal will endanger the coastlines during floods, hurricanes, etc
