Organisms can be divided into two main groups based on fundamental differences in their cell structure. Animals, plants, fungi, and protists are eukaryotes. Bacteria and archaea are prokaryotes. All prokaryotes are unicellular while eukaryotes may be single-celled or multicellular.

vodka [1.7K]

Answer:

Denatured (unfolded) proteins do not function normally.

Explanation:

Proteins are the polymers made of the alpha amino acids that are linked through the peptide bond. Protein is one of the most important biomolecule acts as the main building block of the body.

Protein are specific in functions and works only when they have correct three dimensional structure. The denaturation of protein causes the change in its structure, makes the protein less folded and the protein is unable to perform its function after the denaturation.

Thus, the correct answer is option (2).

Look at the ocean system below.
mash [69]

Answer:

B. Humans will have less salmon available to eat.

Explanation:

First off, you always want to be wary of choices that are kinda extreme. Take for example, choice A., which says All of the oxygen in the atmosphere will disappear. The problem doesn't say that the plankton population will go extinct, just decrease, so oxygen from the atmosphere won't completely disappear. There are also other sources of oxygen. Moving on, C. says that the shrimp will completely disappear from the sea. This is wrong because once again, plankton won't go extinct in the problem. The shrimp population will decrease but not go extinct. Next, D. Choice D is baloney because a decrease in plankton means less food for salmon, which means the salmon would die in the area. That leaves Choice B. Choice B. makes sense because of something called the bottom-up model, which states that an increase or decrease in the amount of organisms in a lower trophic level will affect the organisms in the above trophic levels. We can see that in action here; if the amount of plankton drop, the amount of shrimp salmon will drop, which means less salmon for humans.

The effects of anaerobic conditions how would anaerobic conditions (when no o2 is present) affect the rate of electron transport
Romashka-Z-Leto [24]
Anaerobic condition refers to an environmental condition where oxygen is absent. In case of Electron Transport System (ETS) and ATP production, oxygen acts as the final acceptor of electrons. As oxygen is a reactant in ETS and ATP production, unavailability of oxygen can cause no oxidation of the coenzymes or the carriers such as NAPH and FADH2 and no ATP will be produced. Thus, both Electron Transport System and ATP production will stop in the absence of oxygen.
