Answer:
the least likely situation out of those listed here for a scientist to revise her experimental methods, would be if her results support her hypothesis. In this instance, the outcome of the experiment positively provides evidence that the original hypothesis is correct, and the experiment would therefore be a success and not necessarily require repeating.
Explanation:
A) Biological, physical, and chemical.
b) Physical: sediment radioactive material and heat.
c) Chemical: organic/inorganic: heavy metals, nutrients & pesticides.
A biological community of interacting organisms and their physical environment.
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! :)
Answer:
Corona Virus is helping the environment because people aren't constantly driving around and polluting the air. The economy, however, is dropping due to people not working and not making money and therefore, not spending as much money.
