Explanation:in the process of the scientific method,an observation about an occurrence happens first before an hypothesis is formulated and tested .
Observation usually involves the the description of a phenomenon.
Answer:
Option D, appear in the urine
Explanation:
It is mentioned in the question that Tm for a particular amino acid is 120 mg/100 ml , but the concentration of amino acid in blood is 230 mg/100 ml. Thus, there is an excess of amino acid in blood. The excess amino acid is drained into kidney during blood purification which ultimately appear in the urine.
Thus, option D is correct
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>
