Answer : The correct option is, They can be seen by human eyes as visible light.

Explanation :

Electromagnetic waves : It is a wave which contains electric and magnetic field. The waves travel at the speed of the light.

They take the form of heat : This statement is wrong because microwave radiations are used which ranges from $10^6-10^9nm$ .

They can cause skin cancer and sunburn : This statement is wrong because U.V waves cause skin cancer and sunburn and the wavelength range of U.V is less than 700 nm.

They are some of the shortest waves : This statement is wrong because the wavelength range of the shortest wave is 100 to 700 nm.

They can be seen by human eyes as visible light : This statement is correct because the wavelength range of visible light is 400 to 780 nm.

I think the conclusion would be that the fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.A barnarcle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustecea, and thus related to crabs and lobsters. B. balanoides is a barnacle that attaches to rocks, especially during intertidal zones while C.stellatus is a species of acorn barnacle common on rocky shores in south West Eangland, Ireland, and Southern Europe.

Drawing a cartoon in pencil, then going back over it later with an ink pen is most similar to which biological process?

Montano1993 [528]

Given that the main reason for which an artist will retrace a drawing in pen is to correct errors and achieve a final draft, we can compare this to the biological process of DNA proofreading.

DNA proofreading is a biological process that takes place during the biosynthesis of DNA. During this time, a chain of DNA is read and a complementary chain is creating, effectively duplicating the genetic code.

During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again.

The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw valid comparisons between the retracing of a cartoon and the proofreading of DNA by the DNA polymerase enzyme.
