Why are the moon’s craters preserved?

Answers

The main reason is that there is no atmosphere. This means that there is no weather and no weather means that there is no wind or rain. Wind and rain are main components of erosion and because there is no erosion, craters can stay preserved for a very long time.

Approximately 99% of the microbes in the intestines are obligate anaerobes. We have plenty of blood vessels that can bring oxygen to the tissues of the intestines. Why would there be obligate anaerobes within these areas? A. The bacteria in the intestines are protected from exposure to the oxygen in the tissues by the lining of the intestines. B. The bacteria consume all the oxygen in the tissue areas brought by the blood vessels, creating an anaerobic environment. C. While the blood vessels supply oxygen to the tissues of the intestines, the inner area where the bacteria reside is NOT supplied with blood/oxygen. Since it's deep within our bodies, there's no chance for oxygen to get into these inner areas of the intestinal tube, creating a highly anaerobic environment. D. The aerobic microbes are outcompeted for nutrients in these areas by the anaerobic microbes.

Answers

Answer:

The correct answer is option C.

Explanation:

The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.  

The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.  

These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.  

Imagine you discover a yeast mutant that exhibits a general inability to grow and thrive compared to wild-type yeast. You predict that the mutant has a defect in a basic process necessary for survival and therefore examine the cellular levels of 200 common proteins, as well as the levels of tRNAs and rRNAs. You discover that tRNA and rRNA levels are normal, but the levels of all of the proteins you examine are much lower than they are in the wild-type yeast. This suggests that there is a general defect in:

Answers

Answer:

Some of the other process of gene expression

Explanation:

If the tRNA and rRNA levels are normal we can assume that the translation machinery is working properly. So, this suggest that the defect might appear in some of the previous steps of gene expression: replication, transcription, mRNA processing.

Gene expression is a set of processes that occur in the cell and that use information from the genetic material (gene) to produce gene product (e.g. protein). Gene expression is highly controlled and regulated because it is critical for an organism's development.
