Th earth scientists have improved our understanding with the environment because of their studies in which they had shown better understanding and explanation of occurrences with the means of having to provide not only explanation nor visuals but also providing proof of these mere existence that made people believe and understand the environment.
Number 2 but I am not sure sorry dude
Answer:
Emulsifier generally reduces the surface tension of the lipid there by helping in the digestion of the lipid molecules.
Explanation:
Bile that is secreted from liver act as emulsifier because the bile helps in the break down of lipid into small molecules to form micelle thereby reducing the surface tension of the lipid molecules.
Due the formation of micelle the broken down lipid molecules binds to the active site of the lipase enzyme and get digested to form fatty acid and glycerol.
Beside digestion Emulsifier Bile also helps in the absoption of lipid from the small intestine.
Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
