An orange roughy fish is a fourth-level consumer that requires almost ten times the amount of food available from the primary producers in the ecosystem. Why isn't more energy available from the primary producers?A. Primary producers are not very efficient and lose most of their energy to the environment.B. There is too much competition from other fourth-level consumers, leaving very little available to the orange roughy.C. Only a fraction of energy is passed through each level, so there is less available to upper-level consumers.D. The energy flow is unbalanced and tends to move toward the lower levels.
Imagine you are a geneticist interested in studying a newly discovered species of very colorful birds. You have found that a single gene is responsible for their beautiful colors and that yellow birds are homozygous for the yellow allele, blue birds are homozygous for the blue allele and green birds are heterozygous for these alleles. You focused your efforts on studying one specific population and counted 9% yellow, 49% blue and 42% green birds. What are the allele frequencies in this population?\

Arrange the tiles to show the sequence of the steps in a scientific investigation. make an observation ask questions construct a hypothesis test the hypothesis analyze the results and make conclusions communicate the results

Answers

Answer:

The correct answer will be-

1. make an observation

2.ask questions

3.construct a hypothesis

4. test the hypothesis

5. analyze the results

6. make conclusions

7.communicate the results

Explanation:

A scientific method is a systematic approach to answer and explain the natural phenomenon of nature.

The scientific method begins with making an observation based on which the researcher can frame scientific questions which could be answered. The researcher must do background research on the same question and predict the most probable reason in the form hypothesis.  

This hypothesis must be tested by performing the experiments designed to test the hypothesis. Based on experiments results must be collected and analysed as a piece of evidence to make conclusions regarding the hypothesis. These results must be communicated through poster presentations or in published form in journals after peer-reviewed.

Thus, the steps are arranged in accordance with the scientific method.

Final answer:

The sequence of steps in a scientific investigation includes making observations, asking questions, constructing a hypothesis, testing the hypothesis, analyzing the results, and communicating the results.

Explanation:

The sequence of steps in a scientific investigation is as follows:

  1. Make an observation: A scientist makes an observation about a pattern or trend in the natural world.
  2. Ask questions: The observation generates questions that the scientist wants to answer.
  3. Construct a hypothesis: The scientist formulates a testable statement that explains the observation.
  4. Test the hypothesis: The scientist performs an experiment to gather data.
  5. Analyze the results and make conclusions: The scientist analyzes the data and draws conclusions based on the results.
  6. Communicate the results: The scientist shares their findings with others.

Which of the following could be a hypothesis for what causes a scarlet ibis to have red feathers?A. the red feathers make the bird more beautiful to people
B. A chemical in the birds food produces the red coloring
C. What does the scarlet ibis eat?
D. The feathers are red because a wizard cursed the bid long ago

Answers

The answer is C because it seems like the most logical answer

Final answer:

The hypothesis for what causes a scarlet ibis to have red feathers is that a chemical in the bird's food produces the red coloring.

Explanation:

B. A chemical in the bird's food produces the red coloring. In this case, the hypothesis suggests that the red feathers of the scarlet ibis are caused by a specific chemical component present in the bird's food. This hypothesis can be tested by conducting experiments to analyze the bird's diet and investigating the effects of different foods on the coloration of the feathers.

A wildlife biologist suggests re-introducing the eastern cougar into southern Alabama, reasoning that besides bears, which can survive off of berries and grubs, there are no large natural predators, and that it would be good for the food chain. It is assumed that the eastern cougar would eat deer, which in turn, graze on tree bark, shrubs, and leaves. The average cougar weighs about 100 pounds, as does the average deer. The average cougar has a range of one square mile. A recent biological study showed that there were about 16 deer per square mile in Alabama, an average about 40,000 pounds of vegetation per square mile, and an average of 9.5 people per square mile in southern Alabama. Despite the biologist's proposal, other biologists vote against re-introducing the cougar. Which of these is a possible VALID reason for this?
