Answer:
H+
Explanation:
Hemoglobin is the major protein of red blood cells. It has many exposed amino groups and carboxylic groups at its surface. These NH3 and COOH groups serve as weak acids and bases respectively and allow hemoglobin to serve as a buffer to maintain the pH of the RBC cytoplasm.
As the exposed amino groups of hemoglobin protein bind to the H+ ions, the free H+ concentration of the cytoplasm of RBC is reduced leading to a buffer action to maintain the pH.
Answer:
The correct answer would be "Can prevent genetic diseases".
Cloning refers to the process of making an identical copy of organism, cell or DNA fragments.
One of the applications of cloning is eradication or prevention of genetic diseases.
It is done by isolating the correct or functional gene and make copies of it in in-vitro conditions.
The gene or DNA fragment is then inserted back into the cell.
With advancement in cloning process and understanding of stem cells, cloning process also favors tissues and organ harvesting which also help in reducing diseases.
Quartz
Explanation:
Quartz is a framework silicate made up of interlocking SiO₂. It is the most resistant mineral to weathering.
This is based on the Bowen's reaction series of minerals.
From the series;
- In a given melt, quartz is the last mineral to crystallize out of solution.
- Olivine is usually the first
- Quartz being the last does not readily react with other substances.
- This makes it resistant to agent of weathering.
