Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)
Binary fission is the process of a bacterial cell going from singular to double. Therefore the correct answer would be: "During binary fission, a bacteria cell grows in size because DNA and other organelles are duplicated."
The answer is
C. The way the layer interacts with the layer below it.
Oxazolidinones, Ansamycins, and Tetracyclines
These class of antibiotics are mean't to disrupt bacteria that are gram positive.
