The NH2 group, is the group that conform the amines groups. Also, in organic chemistry, this gruop is the base and in the most common reactions works like that, for example:

Which of the broad categories of resource use account for a disproportionate (or the largest) amount of your ecological footprin
enot [183]

The total productive areas in which a population, a person, or a product competes are tallied as ecological footprint. It gauges the ecological resources needed by a particular population or product to produce the natural resources it consumes (such as plant-based food and fiber products, livestock and fish products, timber and other forest products, and space for urban infrastructure), as well as to absorb its waste, particularly carbon emissions.

<h3>What is ecological reserve/deficit?</h3>

An ecological deficit happens when a population's ecological footprint exceeds the biocapacity of the space that population has access to. If a country has a national ecological deficit, it is either importing biocapacity through commerce, selling off its ecological resources, or releasing carbon dioxide waste into the sky. When a region's biocapacity surpasses its population's ecological footprint, an ecological reserve is created.

Approximately 99% of the microbes in the intestines are obligate anaerobes. We have plenty of blood vessels that can bring oxyge
garik1379 [7]

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.

Answer:

What is a good example of a response-based definition of stress?

Bruce experiences stress because his heart rate increased when he noticed Jack had a knife.

Explanation:

Stress can have many different causes. In this case, it is produced by seeing danger in Jack by having a knife. His heart rate increases because this is a common response in stress, which would enable people to scape. It is important to control stress lebels.

A stressor is distinguished as a threat. If someone anticipates that it could lead to some kind of harm, loss, or other negative consequence. However, if you see the positive side and believe that it carries the potential for gain or personal growth, it would be appraised as a Challenge.
