Answer:
Explanation:
This is due to isostatic equilibrium.
Isostatic rebound occurs when load is added or removed on the lithosphere and the surface either sinks or rises under the weight of the asthenosphere.
At first, when load which can be in form of glacier is added to the lithosphere, this block of the earth would sink rapidly at first due to the added weight. With time, as the adjustment continues, an equilibrium is now reached between the lithosphere and the asthenosphere. At this point, the asthenosphere would have gathered enough strength to carry the overlying weight.
The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.
(A) the softest layer of rock?
Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.
C they will adapt and eventually become a new species
