Compound microscope is commonly used in the schools and colleges. It has two lenses, the objective lens and the ocular lens. It provides a magnification of 1500X. Eyepiece lens is of 10X or 15X power. It is used to observe bacterial, protozoa, various cells, etc.
Dissecting Microscope It is also called stereo microscope. Its magnification power is less than the other microscope. It gives a 3 dimensional picture. Due to the low magnifying power they are used to observe little bigger objects than other microscopes. They are used in the surgeries, dissection, forensic science etc.
Capillaries are made up of very thin and flat tissues that are spread across the body. Substances are able to diffuse through the capillaries because of the presence of blood. Particularly, the red blood cells that make-up blood within the body. These cells have the ability to carry oxygen, carbon dioxide, glucose, and water to pass through the capillaries.

So, the above condition of Mr. Jackson shows pulmonary embolism.
The correct answer is: 2.5%
The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.
• Telomeres-ends of DNA with protective role (prevents shortening of DNA),
• Non-coding RNA genes-e.g. genes for tRNA,
• Gene regulatory sequences such as promoter, enhancers and silencers.
