Microscopes have been used for centuries in order to see specimen scientists cannot see with their unaided eye. Antón VanLeeonhoeuk is given credit for designing the first lenses for microscopes in the 16th century. He looked at “animacules” which we would now call bacteria and protists. Robert Hooke first coined the term cell, as he looked at cork and thought it looked like cells that monks slept in. Improvements were made in the following centuries, and Ernest Leintz in the 1800s creates a way to have differing magnification lenses on one microscope. Continuing into the 1900s and 2000s there are now electron scanning microscopes, ultraviolet microscopes, atomic force microscopes, and electron tunneling microscopes—all which allow scientists to have better resolution and to see smaller and smaller things. Microscope technology will continue to improve as scientists discover more ways to magnify the microscopic world.

Answer:

paraplegic. Given the situation the nurse is expected to provide an
explanation to the family without using jargon words. Paraplegic is known to be
a condition where a patient’s lower extremities are paralyzed.
Cellular respiration is a cellular process in the metabolism of sugar components to produce metabolites such as lactic acid, acetic acid, aldehydes, and other components. It starts with the cleaving of the sugar component (6-carbon) to 3-carbon components until it becomes pyruvate
