The answer is A
The wavelength of the radiation energy it emits
Answer:
The correct answer or fill in would be- but <u>Change and evolve</u> over time.
Explanation:
The perfect cosmological principle is a extended version of the cosmological principle. The perfect cosmological principle says that the universe is look same from all directions but can be change and evolve with time.
Steady state theory supports this theory as it also says that universe is expanding but also maintain its density even though it continuously creates stars and galaxies but still look same.
Thus, the correct answer is - but <u>Change and evolve</u> over time.
Answer:
Billions of dollars of foreign aid has poured into Haiti with little to show for it. This is largely because that money has come to do for Haitians what, with a little help in expertise, they could have done for themselves. This is the biggest difference between aid and development. As a result, 74% of Haitians are either unemployed or under-employed and 8.5 million live on less than $2.41 per day.
Aid is designed to help with immediate needs. As important as that is at times, aid is not the solution to Haiti’s long term challenges. The Haitian people are the solution to Haiti’s problems, particularly those who have the skills and character to build a stronger Haiti for all.
By helping men and women gain the skills to build, train, and lead, you have the power to unleash Haiti’s potential to create a stronger future. Through Extollo’s unique approach to development you will help build stronger careers, stronger families, stronger communities, and a stronger infrastructure for all Haitians.
Explanation:
Answer:
Mechanical Isolation
A snail with a flat disc-like shell
will not be able to mate with a
snail having a conical shell.
The reproductive organs of
male bush babies do not
match with the reproductive
organs of females of other
bush baby species
Behavioral Isolation
The mating call of a cricket is not
recognized by a cricket of other
species.
The signals sent by a male firefly
are not recognized by the female
firefly of other species.
Explanation:
Mechanical isolation occurs in the scenario where two organisms are willing to mate but cannot do so due to the physical challenges. As in the case of snail a flat disk and a conical disk snail are willing to mate but physical barriers restrict them in doing so.
The same case is with the male and female bush babies where the difference in reproductive organs does not allow them to mate.
Behavioral isolation represents a scenario where two organisms are unaware of mating rituals, season, pattern or signals of each other and hence cannot mate.
For example – male and female cricket do not recognize the mating call of each other. Likewise male and female firefly is also not able to understand each other’s mating signal.
No, each cell is specialized for certain functions and will transcribe genes when they are needed.
Hope this helps!
