  • From different wavelengths we can create a electromagnetic spectrum .
  • From spectral lines of that electromagnetic spectrum astronomers can determine the element in the farther universe (star).
  • They can also determine the temperature and density of that element in the star.
  • The spectral lines in the electromagnetic spectrum tell us about any magnetic field of the star.

A useful formula of wavelength:

\\ \sf\longmapsto \lambda=\dfrac{c}{v}

  • c is the speed of light
  • v is the frequency

Electromagnetic waves have many different wavelengths and frequencies that span a range known as the electromagnetic spectrum Light of different wavelengths produces different perceptions of color. The longest wavelengths produce the perception of red, while the shortest ones produce the perception of violet.

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>

<em>The correct option is C. </em>

How is the skeletal system important to the process of cellular respiration?
olchik [2.2K]

Answer:

The body's cells use oxygen for metabolism, and this process creates the waste product carbon dioxide. With the help of the lymphatic and circulatory systems, the skeletal system works with the respiratory system by creating red blood cells in the bones that aid in respiration facilitated by the lungs.
