Answer:
BS is caused by the increasing use of air conditioning in modern offices, leading to bacteria build-up in the ventilation systems. Using UV lights to fight SBS is effective since it is easy and cheap to install, and it could save companies money in reducing the rate of sickness in the employees.
Explanation:
Concerning your heart, that's the circulatory system
Your lungs are the respritaory system
Answer:
the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.
Differences:
- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from
- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases
- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors
Explanation:
Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:
1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.
2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)
3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.
Answer:
The carbon-dioxide exists in the atmosphere, and it is dissolved in the water.
Explanation:
With the process of photosynthesis, it becomes organic, and by breathing, the organic gas goes back to carbon-dioxide.
The assimilation of carbon is the process when the carbon-dioxide converts to organic carbon with the help of living organisms. This organic carbon is then used for energy.
A hypothesis for this observation might be that malaria is not endemic to southern Africa. It is a plausible explanation of a given scientific question.
<h3>Hypothesis and scientific method</h3>
A hypothesis is a plausible explanation of an observation of the natural world, which must be tested by using the scientific method.
Testing a hypothesis involves performing additional observational and/or experimental procedures in order to confirm or reject this assumption.
In this case, the sickle cell allele is found in high frequency in regions where malaria is endemic.
