Answer:
Trisomy
Explanation:
A trisomy is a type of polysomy (presence of three or more copies of the chromosome rather than the expected two copies) in which there are three copies of a particular chromosome, instead of the normal two. A trisomy is a also a genetic disorder and a type of aneuploidy (an abnormal number of chromosomes either an increase or a decrease). Examples include trisomy 21 (Down syndrome), trisomy 18 (Edward syndrome), trisomy 13 (Patau syndrome)

Answer: The excretory system.
Explanation: The excretory system's function is to filter out cellular wastes, toxins and excess water or nutrients from the circulatory system.
the genetic constitution of an individual organism.
The answer is nitrogen. It is usually regarded as a growth-<span>limiting</span> factor for <span>primary</span> <span>producers</span> such as <span>phytoplankton</span>. It is <span>usually</span> taken up in the ‘fixed’ form of ammonium. It is converted from
<span>dissolved</span> nitrogen gas in ocean surface
to a ‘fixed’ form by particular microbes. Due to <span>increasing</span> global <span>temperatures,</span>
as a result of global warming, the ocean temperatures have increased hence
oceans hold less dissolved oxygen than they used to. <span>The low</span> oxygen concentration in the oceans <span>induces</span> the loss of nitrogen from oceans through <span>increased</span> activity of micro-<span>organisms</span> that are significant in
denitrification. This rate becomes higher than that of nitrification that fixes
nitrogen in the oceans. <span> </span><span> </span>
