What did the microscope contribute to science?
The microscope enabled scientists to magnify their observations, allowing research and the study of cells, bacteria, animals, etc.
Describe the two pieces of information from other scientists that enabled James Watson and Francis Crick to discover the double-helical structure of DNA?
Before Watson and Crick could discover the shape of DNA, Swiss chemist Friedrich Miescher had to discover DNA in the first place. Later, Phoebus Levene and Erwin Chargaff would begin investigating the structure of DNA.
How is gradualism evolution different from punctual evolution?
When Darwin first published his theories on evolution by natural selection, he envisaged evolution as a slow, steady process, with little variation in the rate of change. Later discoveries showed that this process was unlikely to be so slow and steady as was thought earlier; that in stead certain conditions enabled lifeforms to change rapidly, to develop significantly different morphologies in the course of less than 10.000 generations even. The first scientists to formulate such a model were S.J. Gould and N. Eldridge, and their model was called 'punctuated equilibrium'. To summarize: the significant difference between Darwin's gradualism and Gould's punctuated equilibrium is the variation in the rate of change.
Do all diploid cells in the human body contain the same genetic material?
Yes. Every diploid cell in the same organism has same DNA, with the same information (excluding possible mutations). Depending on the type of cell different genes are enabled or disabled, but in a cell of your big toe all genetic info is present to work as a brain cell, and vice verse. Exception: Chimerae, here two eggs with different genetic information resulted in one organism. The opposite of identical twins.
How did the Compound Microscope change life as people know it?
the compound light microscope provided people the ability to see objects too small to see with the naked eye. It also enabled microscopes to magnify at different rates, usually 100x, 400x and 500x.
Which of these technological advances enabled information to be recorded and passed from person to person?
The Printing Press
Which of technological advances enabled information to be recorded and passed from person to person?

How has the nonmetallic minerals services industry benefited from technological advances?
"walking machines" loaded with cameras, sensors, and measuring equipment have enabled researchers to explore inhospitable terrain remotely and may prove to have applications in the field of mineral exploration
What invention enabled scientists to view cells?
microscope
Which technique enabled scientists in the 1800's to identify the organelles?
Staining enabled scientist to identify cell organelles.
What two eruptions enabled scientists to study them?
saint helens

What technological innovations enabled the construction of skyscrapers such as the Seagram building in new york city?
My dick
What 2 technological innovation enabled the first skyscrapers to be built?
Two technological innovation which enabled the first skyscrapers to be built were the development of the elevator by inventor Elisha Otis and the design of steel structural supports for tall buildings by architect William Le Baron Jenney.
How did technological advances in transportation and communication affect in industrial revolution?
Principally, transport developments enabled larger quantities of materials and goods to be moved, more rapidly and efficiently, hence more cheaply, than hitherto. The initial development was of the canals in the 18C; slowly supplanted by the railways in the 19C. Communications were still by letter-post but improvements in road-making methods in the 18C enabled faster carrying.
How are scientists able to track the hole in ozone?
Scientists are able to track ozone hole. New technology has enabled them to do so.
