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.
The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.
Explanation:
In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.
This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.
Because the lava cools quickly, there is no time to create big crystals of Basalt, which means that only small ones that are not visible to the naked eye exist, which means that it has an <span>aphanitic texture.</span>
