Reflected light obeys the law of reflection, that the angle of reflection equals the angle of incidence. For objects such as mirrors, with surfaces so smooth that any hills or valleys on the surface are smaller than the wavelength of light, the law of reflection applies on a large scale.

Darwin observed that organisms that were best able to survive and reproduce had adaptations that were...
11111nata11111 [884]

Answer:

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

Hope this helped!

Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
