<span>Ptyalin hydrolysis does not continue in the stomach because it is destroyed by the stomach once it enter the stomach. </span>
Ptyalin is an amylase enzyme commonly found in the saliva of
humans and animals. This enzyme is secreted in the mouth ( buccal cavity) and catalyze
the hydrolysis of starch into maltose and dextrin. Immediately the starch
leaves the mouth and enter the stomach, stomach acids destroy the ptyalin.
Great reading kid hope u pass
Answer :
The animals are categorized into 2 groups - eukaryotes and prokaryotes. The microbes like bacteria are coming under prokaryotes. They are unicellular organisms and without a true nucleus.
Viruses are the connecting link between the living and non - living. They are smaller than bacteria. The microbes less than 100 micrometer can't be seen by the naked eye. They can only visible under a microscope.
Viruses like polio, flu virus sizes are 10nm. But some of the viruses are also less than 10nm. The size of bacteria is 1 micrometer. The viruses are 10 times smaller than the bacteria.
The eukaryotic organisms are more advanced and multicellular. Their cell size is larger than bacteria and viruses. The red blood cells under the light microscope are 8 micrometers. The typical animal cells like sperm are 60 micrometers and a skin cell is 30 micrometers. The plant cell for example pollen is 90 micrometers.
The eukaryotic cells sizes are more than prokaryotes like bacteria.
All/most- ethyl acetate, toluene, aliphatic polyisocyanante, hexamethylene disocyanate, methyl ethyl ketone, dibastic esters, petroleum naphta, bismuth
White - titanium dioxide, zinc
red - iron oxide, cadmium
orange- iron oxide, cadmium
yellow- iron oxide, cadmium
Green - chrome oxide
black- carbon
I got tired of typeing so ----basically they are all made of a pigment which can be a range of chemicals, resin, solvent, and additives. If you are just looking for the main elements in paint, it is silicone, oxygen, and a salt so sodium, chlorine, maybe iodine, or a salt substitute like potassium chloride, potassium nitrate, or calcium hydroxide.
