<u>Answer:</u>
Limited resources contribute to evolutionary change in animals by increasing Intra-specific competition.
<u>Explanation:</u>
- Intra-specific competition means competition among the members of same species.
- Individual of same species have same ecological niche i.e. how an organism is related with biotic and abiotic aspect of environment.
- So they require same resources of their survival. When population of any species increases then there is high chance of intra-specific competition because of limited resources.
- Intra-specific competition also determine the population size of species. For example, competition among shark rodents.
Lichens have been described as "dual organisms<span>" because they are symbiotic associations between two (or sometimes more) entirely different types of microorganism - a fungus (termed the mycobiont) a green alga or a cyanobacterium (termed the photobiont).

Answer:
C. 275 nm
Explanation:
At 275 nm of ultraviolet wavelengths causes mutation in a skin cell because at 275 nm of wavelength, maximum DNA Copying Errors occur in the cells that leads to mutation in the cell. A mutation is a kind of change that occurs in the DNA, due to two reasons, due to mistakes that is occur when the DNA is copied or as the result of environmental factors such as ultraviolet radiations.
Answer:
movement
Explanation:
they act in contractions and help move body parts but work with bones as the bones provide support and allow for movement
We have that the time the earthquake occurred is mathematically given as
The <u>earthquake </u>occurred at =7:03:00 pm
<h3>Co-ordinates</h3>
Question Parameters:
A seismic recording station located 4000 <em>kilometers </em>from the epicenter
an earthquake received the first P-wave at 7:10:00 p.m. (h:min:s).
Generally
From t-x diagram, the x axis marks the distance of the <em>station </em>from the epicenter.
Hence we have that the P wave took 7 min to reach the station.
Arrival time of P and S wave is
dt=5 min 40 sec.
Therefore
The <u>earthquake </u>occurred at =7:03:00 pm
The S wave arrived at = 07:15:40 pm.
