Answer:
<u>Parasitism</u>
Explanation:
Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.
When the starfish were removed from the area as part of an experiment, the mussel population swelled and crowded out other species. The biodiversity of the ecosystem was drastically reduced. Payne's study showed that identifying and protecting keystone species can help preserve the population of many other species.
To put it simply, ionic bonds form when one atom transfers an electron to another atom. The atom that gains an electron becomes a negative ion while the atom that loses an electron becomes a positive ion. Covalent bonds form when two atoms share electrons. A hydrogen bond is when you have a negatively charged O, N, or F atom in one molecule, a positively charged H atom latched on to an O, N or F atom in another molecule. An example of a hydrogen bond is water.
Yes.
Both of them have vacuoles but the diffrences are-
plants have a cell wall and chlorophyll. <span />
The number of electrons in the outer shell determine its reactivity or tendency to form chemical bonds with other atoms.
