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.
Answer:
Bacteria can have one flagellum or several.
Viruses aren't made up of living cells, like plants and animals are, they either consist of DNA or RNA surrounded by coating of protein. Versus also like the properties of living things. They have no energy, they do not produce waste, and they do not respond to stimuli. they do not reproduce independently but must rely on invading living cells and feeding off a them.
Therefore, there are many reasons my viruses are considered non living but the biggest reason is because they cannot survive on their on and have to feed and get their nutrients off of living things
And bacteria is considered living because it can do all these things that viruses cannot do.
Answer:
The nutrient cycle describes the use, movement, and recycling of nutrients in the environment. Valuable elements such as carbon, oxygen, hydrogen, phosphorus, and nitrogen are essential to life and must be recycled in order for organisms to exist.

Answer:
the questions are asking you like what is the carrying capacity for the rabbits and etc.So you take the information from the graph and answer the questions with the information that it is giving you from the graph. I hope this answers your question.
