What a great way to see how bacteria exposed to Martian-like conditions will survive. By testing how well these bacteria do in the stratosphere we can gain insight into several things. 1) the likelihood that any bacteria still survives on Mars 2) how well bacteria introduced to Mars could survive and if there are existential risks to doing so and 3) how bacteria introduced to harsh conditions react more broadly, even on earth.
The dam could burst or, if not properly constructed cause water to spill over the sides and top of the dam. Hope this helps.
I think D is the correct answer....
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. ... During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction!! (TY):D
Answer: (A) Genetic drift
Explanation:
The genetic drift is one of the process of random sampling in which the existent gene frequency are get changed in the organisms and it is also refers as the allelic effect.
According to the given question, In a small remote area the different types of people are living and in that area the "Blue skin" condition is highly incidence due to the variation in the hemoglobin structure.
So, the high frequency in the Blue skin in that specific area is one of the example of the genetic drift and the main role of the genetic drift is to determining the sampling error from the different generation gene.
Therefore, Option (A) is correct answer.
