Sharks obtain all of their energy by eating other marine organisms, such as fish. Suppose that a marine scientist measures the c

hemical energy found in a system consisting of a fish and a shark. After the shark consumes the fish, the marine scientist finds that the total energy in the system decreases. If true, would this result validate or invalidate the Law of Conservation of Energy? Why or why not?
Invalidate, because energy should not leave a closed system

Invalidate, because the amount of energy should stay constant

Validate, because this scenario describes an open system

Validate, because the overall energy in the ocean is still unchanged

1 and 6 are correct

Explanation:

1. A and B are probably closely related - true, as reflected by their close gene sequences which usually represents a very close genetic relationship

2. B and C are probably closely related  - false, if their gene sequences are very different then they are probably not so closely related

3. A and C are probably closely related  - false, we know A and B are close, and B and C are very different, therefore A is probably also very different

4. B is probably an outgroup while A and C are sister taxa  - false, A and B are highly similar

5. A is probably an outgroup while B and C are sister taxa  - false, B and C are very different genetically

6. C is probably an outgroup while A and B are sister taxa - true, we know A and B share similar gene sequences, whereas C is distinct.

<h3>What is the role of the oral dentist?</h3>

Tooth extractions are carried out by dental and oral specialists for various reasons. A painful tooth or a tooth that has been significantly affected by decay may be the problem. Sometimes a dentist will extract a tooth to make room for dental prostheses or other devices.

When the situation becomes increasingly complicated, an oral expert rather than a dental professional may need to extract a tooth. They typically remove wisdom teeth or third molars.

The dental professional or specialist will initially numb the tooth to gradually relax the patient. Even though tooth extraction may still be distressing, it may be essential for relieving dental pain and preventing further problems.
