Part D A scientist comes up with an idea to reintroduce a shark that eats lionfish into the Atlantic Ocean. What are the possible benefits and risks of this idea? In your answer, state two questions you’d ask the scientist before agreeing to the plan.
Answer:
The shark may balance out the lionfish population. However, its presence in the ocean may also negatively affect other organisms. The shark may start preying on natural species, leaving little food for native predators. Two questions to ask the scientist are, Does this shark have any natural predators in the Atlantic Ocean to help control its population numbers? and What other organisms does the shark eat?
Explanation:
i got this from edmentum-
Although some species of grouper and shark may be able to eat them, lionfish have relatively few predators in the area they have invaded because of their deadly spines. Although lionfish are widely distributed, most sharks won't readily eat them.
What eats lionfish into the Atlantic Ocean?The shark might maintain lionfish populations in balance. Its presence in the ocean, however, might also have a harmful impact on other organisms. It's possible that the shark will start eating native animals, leaving little food for them.
Do this shark's natural predators in the Atlantic Ocean aid to regulate its population numbers? Are two queries to put to the expert. What other kinds of creatures does the shark consume?
Therefore, Because the Moray was discovered in a location where divers would not have been searching, this is the first confirmed instance of natural predation of the invasive lionfish in the Atlantic Ocean.

Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1:1 binding of heparin to antithrombin III seems to cause a conformational change in the protein that greatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin
Answer:
Positively charged amino acids
Explanation:
Heparin is an acid polysaccharide that has a strong negative charge due to the sulfate groups on its glucosamine residues. This negative charge confers to heparin anticoagulant activity. The negatively charged groups in the heparin molecule can interact with positively charged (basic) residues, such as arginine (Arg) and lysine (Lys) of plasma proteins. For example, it has been shown that lysine amino acid residues of antithrombin III may be involved in the binding with heparin.

What are the necessary conditions for autotrophic nutrition and what are its byproduct ?
➜ The conditions necessary for autotrophic nutrition are sunlight, chlorophyll, carbon dioxide (CO2) and water (H2O).
The byproducts of autotrophic nutrition are water and oxygen.
Answer:
Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.
earth science: fossils question pls help
Answer:
Layers A and B show cratures that would most likely be found in the ocean (they have fins, etc.) then the next layer has no animals and after that the animals beofre are no longer seen. This must mean that the creatures went exticnt due to an envoirmental issues, in this case its a volcanic explosion (as seen in the key in the corner were the shaded area is indicated as volacanic ash). In layer D, we see a plant, this shows us that the envoirment is now land. After that is another layer of volcanic ash and then F. were we see the previous plants and animlas with the inclusion of 'bird'. I think this means that the envoirment has more greenier wether from the nutrients rich soil (due to the volcanic ash) or another factor.
