A few example are
carbon/uranium dating
genetic variations
similar bone structure among vastly different species. For example: the great blue whale was 2 hip bones and 2 femurs!
Pollution, Population and Development size can all have effects on tempature more polluted places are warmer beleive it or not and buildings can actually absorb a lot of heat however they are usually in cities with large concentrations of people
1. abiotic = non living factors
biotic = living factors
hope this helps :)
Parasites benefit their hosts is the true statement. Parasitism is a symbiotic relationship in which one organism (the parasite) benefits from another organism and this other organism is harmed by the parasite.
The others aren't true because:
- the organism that is harmed doesn'y adapt and evolve it still is vulnerable
- it is a fact that parasites change from hosts
- phoresy is an association between two species in which one transports the other. This does not include killing the host (is possible, but it is not a condition under which you can call something a phoresy).
This is true that the pressure in the mesosphere is so low that a person could not be in this layer without a spacesuit.
The mesosphere is the region of the earth's atmosphere which is above the stratosphere and below the thermosphere. It has a very low temperature and pressure. The top of the mesosphere is the coldest part of Earth's atmosphere.
