Answer:
The levels of carbon dioxide (CO2) in the atmosphere are reduced
Explanation:
Tectonic uplift refers to the process by which the surface of the earth slowly rises either due to increasing upward force applied from the plates below the surface or decreasing downward force or weight of objects like melting glaciers acting from above. During uplift, land, as well as the sea floor rises forming mountains, plateaus and volcanic Islands.
During the process of weathering, carbon dioxide present in air combines with rainwater and forms carbonic acid. This acidic rainwater then falls on uplifted mountains and rocks weathering them in the process. Minerals present in the rock such as calcium, magnesium and sodium then combine with bicarbonate ions to form carbonates such as calcium carbonate, magnesium carbonate which are found in shells of living and dead organisms and also form rocks such as limestone. In this way, carbon dioxide is removed from the atmosphere.
Answer:
Mass = 153.48 g
Explanation:
Given data:
Volume of solution = 2.50 L
Molarity = 0.48 M
Mass required = ?
Solution:
Molarity = number of moles / volume in litter
Number of moles = Molarity × volume in litter
Number of moles = 0.48 M × 2.50 L
Number of moles = 1.2 mol
Mass of HI:
Number of moles = mass/molar mass
Mass = Number of moles × molar mass
Mass = 1.2 mol × 127.9 g/mol
Mass = 153.48 g

Answer:
1. salt bridge - tertiary structure
2. amide bond - primary structure
3. disulfide bond - tertiary structure
4. beta-pleated sheet - secondary structure
5. alpha helix - secondary structure
Explanation:
A salt bridge is simply a neutralisation reaction between two molecules of opposite charge. Examples are: carboxylate ion end (RCOO−) of either aspartic acid or glutamic acid and ammonium ion end (RNH3+) from lysine or guanidinium (RNHC(NH2)2+) of arginine. The disulfide bond is usually gound in the Cysteine amino acid with the structure R−S−S−R′. Also, it is usually derived by the bonding of two thiol groups. They are both important components of protein and they determine the overall structure of protein and hence its fold.
For beta-pleated and alpha-helix structures, they are usually defined by the varying patterns of hydrogen bonds between the amine- (-NH2) and carboxyl-(-COOH) groups which are at the side chain of the amino acids. They determine the geometry of the protein hence why they are secondary structures.
Amide bond is an unbranched sequence of amide(peptide) bonds which form long chains of polypeptides (polyamides). This shows that it is a primary structure. They are also formed by dehydration where the amine- (-NH2) and carboxyl-(-COOH) groups bonds together to form a peptide bond with the loss of water.
