Claim:
Group behavior can increase the chances for an individual and a species to survive and reproduce.
Evidences for the claim:
As the claim suggests that group behavior is favorable for organisms, it increases their chance of survival and reproduction. First of all we have to understand what is group. Group is a collection of same kind of organisms that travel, live as well as perform daily life work together.
- When organisms are living in a large group they have better chances to find a mate.
- Living in a group helps the organisms to save them from the attack of predators, because unity is strength.
- Large groups have more power to access food sources and can find ample source with the assistance of fellow members, than solitary animals.
Additional reputable evidence:
We have often seen the birds that they form a V shape when they fly in air in a group. Now, this group formation in V helps those birds to navigate their pathways in a better way. They have more chances to reach in their destination even if that is far off from their place of departure, because the whole group's navigating ability help to reach a destination faster. They are better able to reproduce, survive there.
Similarly when fish swim in groups, they can avoid the attack of predators and are better able to swim for a longer period of time to reach theri destination.
Conclusion:
Group behavior equips the organisms with protection and support. It better adapts an organism to survive the harsh effects of the environment.
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:
The chemical reaction is C6H12O6 + O2 -> CO2 + H2O + energy.
Explanation:
This can be known as trade in some places and kingdoms. But historically, the spread of ideas and culture is know as Trans-cultural diffusion.
Hope this helps :)
