Luminosity is the total energy that star produce in one second, depending on both the radius of the star and on its surface temperature. Thus, all the star's properties such as its temperature, size, brightness and life span is determined by its luminosity.

Does anyone know how to write a lab reportp
malfutka [58]

Hi

The purpose of writing a lab report mainly is to describe the results of your experiment and the learning outcome of your performed experiment as well.

Here are some important parts of a lab report:

Title Page:

It is not mandatory but it is good to add a title page for overall presentable formatting. It will include the title of your experiment, your name and also if there is a partner his name, the name of your lab as well as supervisor's name, along with the date experiment was performed.

Purpose/Introduction:

It is few paragraphs long tat explains the main objectives of your experiment. It may also include the results as well as  the hypothesis and barf conclusion of experiment.

Materials and Methodology:

This includes the protocols you followed for carrying out a certain experiment and also the main items you used to exectute the experiemnt like equipment, chemicals etc.

Data:

The numerical data you obtain from an experiment can look presentable if you write in the form of table.

Results

It is just an representation of your data in forms of sentences that and results are close to predictable findings and how reliable they look.

Analysis  or Discussion

Here you discuss your results that how they are similar or different to the experiments of similar nature that are already conducted. You can give your opinion as per your knowledge and interpret your results so that they make a sense for the reader.

Conclusions

Just conclude the report in one small paragraph that how your experiment accepted or rejected your hypothesis.

Figures or graphs:

You can include some figures and graphs that support your experiment.

References:

Here you will add the links or citations of the work that helped you in carrying out experiment or writing the lab report like journal articles, website articles etc.

Gene X always produces the same mRNA (one splice form) and the same protein in all cells in which it is expressed. The same amou
AysviL [449]

There are two explanations for this phenomenon: phosphorylation of the protein X in the heart activates its function (Option C) or phosphorylation of the protein X in the kidney and the brain deactivates its function (Option D). Therefore, both Option C and Option D are correct.

  • Phosphorylation is a posttranslational protein modification that is capable of activating or deactivating protein function.

  • Phosphorylation alters the three-dimensional structure of a protein, thereby modifying its function (i.e., activate or deactivate the target protein).

  • Phosphorylation occurs at specific amino acids (e.g., serine and threonine residues) of the target protein.

  • Moreover, mRNA splicing (RNA processing) occurs before the protein state, it is a transcriptional process. This process consists in removing the non-coding regions or 'introns' from pre-mRNA and subsequent joining protein-coding regions or 'exons' to enable the translation of the mRNA into a protein.

  • In consequence, in this case, it is possible that 1-phosphorylation of the protein X in the heart activates its function, or 2-phosphorylation of the protein X in the kidney and the brain deactivates its function. Therefore, both Option C and Option D are correct.

If 3/4 of our planet are covered in water why should we be worried about conserving water?
Oliga [24]
  • 97% of all the water on the earth is salt water, which is not suitable for drinking.
  • Only 3% of all the water is fresh water, and only 1% is available for drinking.
  • 2% of the available freshwater sources is locked in ice caps and glaciers.

With growing population rates and such a small percentage of all the water on earth, it only makes sense that we must preserve and conserve this precious resource.
