Answer:
it is both
Explanation:
it's manure because it's waste matter n a fertilizer because it make plants grows when added to the soil
Answer:
The evolution of the Eukaryote cell is most likely involves the endosymbiosis of an smaller bacteria that might be aerobic bacteria by a larger bacteria.
Then this smaller bacteria must remain in symbiotic association with the larger bacteria and it must evolve in organelles like chloroplast or mitochondria and the larger prokaryotic cell must be evolved in an Eukaryota cell.
This theory is called endosymbiotic theory and is supported by the similarities of organelle like chloroplast and mitochondria present in eukaryotic cells with prokaryotic cells.
Answer:
The answer is B. Van der Waals forces are weaker than ionic and covalent bonds.
Explanation:
In general, if we arrange these molecular forces from the <u>strongest to weakest</u>, it would be like this:
<h3>Covalent bonds > Ionic bonds > Hydrogen bonds > Dipole-Dipole Interactions > Van der Waals forces</h3><h3 />
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the <u>protons and electrons causing an electro-static force</u> which results to the strong bonds. An example would be <em>Sodium Chloride (NaCl)</em>, which when separated is <em>Na⁺</em> and <em>Cl⁻</em>.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through <u>residual molecular attractions when molecules pass by each other.</u> It doesn't even last long due to the <u>uneven electron dispersion</u>. It can be made <u>stronger by adding more electrons in the molecule</u>. This kind of molecular bonds appear in <em>non-polar molecules</em> such as <em>carbon dioxide</em>.
