Answer:
1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.
2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged. Electrostatic interaction also depends upon the nature and mass of body.
b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.
Answer:
Parasitic
Explanation:
The species that is described is a parasitic species. The reason why it will fall into this category is that its key feature is that it is entirely dependent on other organisms for its food. This type of species are not able to produce food for themselves, nor are able to get it from the environment, which is way they have evolved in a manner to use the other organisms. They find a host organisms, attach to it, and then they are extracting the nutrients out of that organism, thus classical parasitism. The extraction of the nutrients can be so severe that the parasitic species can actually kill systemically its host.
