<h3>What are the steps in scientific research?</h3>
The steps in scientific research refer to the steps or procedures that are followed by scientists in making scientific discoveries that explain observed phenomena.
The steps in scientific research are as follows:
- Research question - this is the question that a scientist seeks to answer based on his/her observations
- Hypothesis - statements made by scientists to explain their observations
- Background research - research is done to find support for or against the hypothesis.
- Controlled experiment - tests carried out to disprove or prove the hypothesis
- Data collection
- Data analysis
- Conclusion

#SPJ1
I believe it is the amniotic sac
Answer:
Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane
Explanation:
After being synthesized during the transcription, mRNA (pre-mRNA) must be modified in order to be functional (mature mRNA) and exported from the nucleus for the process of translation.Modification of pre-mRNA include:
- 5' capping-addition of 7-methylguanosine to the 5' end which protects the pre-mRNA
- addition of adenine residues to form a poly(A) tail whic is also with protective role (from ribonuclease digestion)
- RNA splicing-excision of introns and reconection of exons
Modified mRNA can now be transported from the nucleus into the cytoplasm.
Answer:
Pertussis.
Explanation:
Vaccine is given as the preventable measure for the particular disease. Vaccine may contain the weakened or killed antigen, the epitope part of any antigen and the particular DNA or protein.
Pertussis is also known as whooping cough that affects the respiratory system of an individual and can cause pneumonia as well. The vaccine for the pertussis is available in the hospitals for the prevention of pertussis in the future generation.
Thus, the correct answer is pertussis.
<u>Answer:</u>
Greenhouse gas refers to any gaseous compound in the atmosphere that can absorb infrared radiation, thereby trapping heat and keeping it in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.
<u>Examples why greenhouse gases in the atmosphere:</u>
- farming cattle releases methane
- farming rice in paddy fields releases methane
- burning fossil fuels in vehicles and power stations releases carbon dioxide
- deforestation releases carbon dioxide and reduces the absorption of carbon dioxide through photosynthesis
