Answer:
• Increase temperature
• Increase concentration-Increase concentration of the Silver nitrate or of the copper.
• Increase surface area-Grind the copper into powder of break it up into smaller pieces.
A peptide bond ...........................
Answer:
The correct order is -
a. 5 > 3 > 4 > 1 > 2 .
Explanation:
In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .
Answer:
(A) A transversion base substitution causing a missense mutation
(B) A transition base substitution causing a silent mutation
(C) A transversion base substitution causing a silent mutation
Explanation:
There are two types of base substitutions, transversions and transitions. A transition is when the a purine base is substituted with another purine base or a pyrimidine base is substituted with a pyrimidine base (e.g. Purines - A to G; G to A; Pyrimidines - C to T; T to C). A transversion occurs when a purine base is substituted with a pyrimidine base or a pyrimidine base is substituted with a purine base (e.g. A to T; C to A).
There are three main types of mutations, these are missense mutations, nonsense mutations and silent mutations. Missense mutations occur when a base is changed and the codon now codes for a different amino acid to before the mutation. Nonsense mutations occur when a base is changed and now the codon codes for a stop codon causing a premature stop of the translation process. Silent mutations occur when a base is changed but the new codon still codes for the same amino acid as before the mutation.
Answer: Apolipoprotein Al-milano( Apo Aim)
Explanation: Apo Aim is a mutant version of the protein Apolipoprotein Al or Apo al, this mutant protein Apo Aim is more effective than Apo Al at removing cholesterol from cell and desolving arterial plaque and also functions as anti oxidants.
