Who is Charles Darwin?

Darwin is the first of the evolutionary biologists, the originator of the concept of natural selection. His principal works, The Origin of Species by Means of Natural Selection (1859) and The Descent of Man (1871) marked a new epoch.

What is Visible light wavelength?

Visible light wavelengths are between 400 and 700 nanometers. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. When white light shines through a prism, the...

Which of the following is a technology type that is used by scientists to improve human existence?

a) Using viral genes to infect plants with beneficial modifications.
b) Using microorganisms to detoxify human waste.
c) Using artificial bovine growth hormone to increase milk production.
d) All of the above.

Explanation:

All of the technological processes that are mentioned are currently used to some degree to help humans. Yet in some cases, their use is controversial. Viral genes can be used to “vaccinate” plants so that they can resist insects and yield large, healthy crops. Sewage treatment plants add organic material-digesting bacteria cultures to human waste, and convert it into useable form. Cows can be made to produce more milk if given the proper hormones, thus creating an inexpensive and abundant supply of milk. The correct answer therefore, is (D).
