Answer: A)They generate electricity by contact
Explanation: triboelectricity can be simply defined as a phenomenon where static electricity is produced when two different materials are vigorously and continuously rubbed or come in contact with each other. This vigorous and continous contact allow electrons to jump from one material (atom) to another there by creating static electricity.
This characteristics is evident when an individual walks across a carpet while wearing a wool socks, as the wool and the carpet vigorously and continuously rub against one another, electrons are transfered from the carpet to the socks which spread all over the surface of the body. (The body becomes negativity charged while the carpet becomes positively charged) This is why the individual will feel a shock sensation when he or she goes on to touch the door knob due to the static electricity generated.
Answer:
Hi,
The correct answer is option (C) Overhunting led to the extinction of large herbivores species
Explanation:
Herbivores are those animal species that eat plants only.Hunters and gatherers depended on their hunting skills to obtain meat as a source of protein/food for their families.Most of the animals that were hunted were herbivores.Overhunting reduced the number of these species because the process was not controlled thus there was no time for the animals to increase in numbers in the natural process
Best of Luck!
Correct answer: "<span>D - it becomes glucose through the process of photosynthesis"
The atmospheric carbon is absorbed by plants in the form of carbon dioxide and used in the process of photosynthesis. Photosynthesis takes 6 carbon dioxide molecules and 6 water molecules to produce a molecule of glucose and 6 of oxygen. That's where most of the atmospheric carbon is used in.</span>
The answer would be <span>B) </span>Sternomastoid and trapezius :)
