Plants in the desert would have a decreased number of stomata compared to rainforest plants. This is because desert plants need to reduce their water loss and keep out the hot and dry winds
DNA has 3 components; phosphate, a sugar called deoxyribose (a 5 carbon sugar as opposed to the sugar in the picture which is a 6 carbon sugar - glucose) and a nitrogenous base (adenine, thymine, guanosine or cytosine). So if you look at those 3 pictures, the only one is the nucleotide that's part of the DNA.

This is because some of the trisomies (one extra chromosome, three instead of two) are fatal, births cannot survive.
Theoretically, trisomies can occur with any chromosome, but often result in miscarriage.
The types of autosomal trisomy that survive to birth in humans are:
Trisomy 8 or Warkany syndrome 2
Trisomy 9
Trisomy 13 or Patau syndrome
Trisomy 18 or Edwards syndrom
Trisomy 21 or Down syndrome.
Compound Microscope
Some of the parts of a compound microscope are the eyepiece lens.<span> There are two knobs on under the other to one side of the microscope which are used for </span>Coarse focus and Fine focus. There is an<span> illuminator</span><span> at the bottom of the microscopic stand, which sheds a powerful light on the subject under the lens. Other parts include </span>objective lenses<span>, </span>stage with stage clips<span> (where the subject is placed) and r</span>evolving nosepiece. The<span> tube</span><span> connects the eyepiece lens to the </span>turret<span>.</span>
