Ammonia is likely to be the primary nitrogenous waste in living conditions that include <u>lots of fresh water flowing the gills of a fish</u>.
Nitrogenous wastes within the frame generally tend to form toxic ammonia, which need to be excreted. Mammals which includes humans excrete urea, even as birds, reptiles, and a few terrestrial invertebrates produce uric acid as waste.
Aquatic animals in general excrete ammonia. Ammonia is a small molecule that conveniently diffuses throughout skin and gills if enough water is available, however the kidneys inefficiently excrete ammonia. Ammonia is exceedingly toxic, and animals cannot continue to exist even mild ammonia concentrations in their frame fluids.
As a result, the marine organisms excrete ammonia without delay into the water and are referred to as ammonotelic. Ammonotelic animals consist of crustaceans, platyhelminths, cnidarians, poriferans, echinoderms, and other aquatic invertebrates.

Answer:
Two-thirds, three-fourths
Explanation:
The constitutional convention includes the amendmend in the constitution or bring a new constitution into effect. For this reason the constitution allows that two-third of the total states must propose a national constitution convention and propose what are amendmends which are required and important. After a long debate held, the right of vote is given to every state for bringing this constitutional amendmend or new constitution into effect. So to approve the constitution to bring into effect the three-forth of the states have to approve.
The correct answer is social exclusion
Social Exclusion designates a process of removal and deprivation of certain individuals or social groups in different areas of the structure of society.
It is a condition inherent in contemporary capitalism, that is, this social problem was driven by the structure of this economic and political system.
Thus, people who have this social condition suffer from various prejudices. They are marginalized by society and prevented from freely exercising their rights as citizens.
Socially excluded people are usually ethnic, cultural and religious minorities. As examples, we have blacks, Indians, the elderly, the poor, homosexuals, drug addicts, unemployed people, people with disabilities, among others.
Note that these people or social groups suffer a lot of prejudice. This directly affects aspects of life, and in many cases creates another problem called "social isolation".
