The scientific method includes the problem statement, previous knowledge, hypothesis and goals, methodology, results, and discusion/conclusion. The correct option is C.  form a <u><em>conclusion.</em></u>

----------------

The scientific method is a research method that consists of s<em>ystematic observations, measures, experimentation, analysis, and verification of a hypothesis.</em> It is based on reproducibility and refutability.  

When conducting an experiment, you need to consider,

Definition and problem statement. The question for which there is not an answer yet. A question the investigator wants to answer.

Theoretical framework. Antecedents from other investigations. Previous knowledge about the study object is always required for a better understanding.

The main goal of the study is basically what the investigator wants to find out.

Hypothesis formulation. The researcher makes a hypothesis to predict or make a conjecture -not verified and which requires corroboration- about what is going on or expected to happen.  

Identification of the study groups, involved variables -independent, dependent, and control-.

Methodology description. Steps needed to get data.

Results. It includes data statistical analysis. This step involves testing the observations.

Discussion and Conclusion, through which the hypothesis might be rejected or accepted.

In the exposed example, the researcher has already collected field data, and made analysis.

Probably, the marine biologist noticed, while analyzing the results, that turtles lay eggs from May to October. But there might have been a biotic or abiotic factor threatening the survival of the eggs during august.  

According to the analysis the researcher concluded that the <em>nest season</em><em> involves monthes between may and october, and august turns to be the most</em><em> critical month </em><em>for nesting. </em>

gtnhenbr [62]

In what ways can the use of statistics help in improving mental health services? Could the use of statistics cause potential misunderstandings of mental health services? How can you avoid any such misunderstandings?

Myths, misunderstandings, and negative stereotypes and attitudes surround mental illness. These result in stigma, discrimination,and isolation of people with mental illness, as well as their families and carers.

----------------------------------------------------------------------------------------------------------------

Are mental illnesses a form of intellectual disability or brain damage?

No. They are illnesses just like any other, such as heart disease, diabetes, and asthma. Yet the traditions of sympathy, support, and flowers given to people with physical illnesses are often denied to those with a mental illness.

Are mental illnesses incurable and lifelong?

No. When treated appropriately and early, many people recover fully and have no further episodes of illness.

For others, mental illness may recur throughout their lives and require ongoing treatment. This is the same as many physical illnesses, such as diabetes and heart disease. Like these other long-term health conditions, mental illness can be managed so that individuals live life to the fullest.

Although some people become disabled as a result of ongoing mental illness, many who experience even very major episodes of illness live full and productive lives.

Are people born with a mental illness?

No. A vulnerability to some mental illnesses, such as bipolar mood disorder,can run in families. But other people develop mental illness with no family history.

Many factors contribute to the onset of a mental illness. These include stress, bereavement, relationship breakdown, physical and sexual abuse, unemployment,social isolation, and major physical illness or disability. Our understanding of the causes of mental illness is growing.

Can anyone develop a mental illness?

Yes. In fact, as many as one in five Australians may develop a mental illness at some stage in their lives. Everyone is vulnerable to mental health problems.

Many people feel more comfortable with the notion of having 'a nervous breakdown' rather than a mental illness. However, it is important to talk openly about mental illness, as this reduces the stigma and helps people to seek early treatment.

Are people with mental illness usually dangerous?

No. This false perception underlies some of the most damaging stereotypes. People with a mental illness are seldom dangerous. Even people with the most severe mental illness are rarely dangerous when receiving appropriate treatment and support.

Should people with a mental illness be isolated from the community?

No. Most people with a mental illness recover quickly and do not even need hospital care. Others have short admissions to hospital for treatment. Improvements in treatment over recent decades mean that most people live in their communities, and there is no need for the confinement and isolation that was commonly used in the past.

A very small number of people with mental illness need hospital care,sometimes against their will. Improvements in treatment are making this less and less common, and fewer than one in a 1000 people are treated this way.

What causes water buttercup cells with the same genotype to have different phenotypes?
djyliett [7]
An organism's genotype is a major (the largest by far for morphology) influencing factor in the development of its phenotype, but it is not the only one. Even two organisms with identical genotypes normally differ in their phenotypes. One experiences this in everyday life with monozygous (i.e. identical) twins.
