Answer:
The answer to your question is: letter A
Explanation:
a. Ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit. This is the main difference between Ribonucleotides and deoxyribonucleotides, the first have hydroxyl group in carbon number two, while the second have a hydrogen.
b. Ribonucleotides contain a phosphate group.
c. Ribonucleotides have a hydrogen atom on the 1 carbon of their sugar sub-unit.
d. Ribonucleotides contain a sugar with five carbon atoms.
Answer:
Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.
Answer:
1. 0.82 gram of Ag+
2. 4.79 g of Ag₂O₃S
Explanation:
From the given information:
Total amount of Ag₂O₃S = 2.24 grams
Atomic mass of Ag+ =107.86 g/mole
molar mass of Ag₂O₃S = 295.8 g/mole
∴
The mass of the Silver (Ag) in grams is:
= 0.82 gram of Ag+
2.
Here, the total amount of Ag₂O₃S = unknown
Atomic mass of Ag+ = 107.86 g/mole
molar mass of Ag₂O₃S = 295.8 g/mole
amount of Ag+ = 1.75 g
∴
The mass of Ag₂O₃S = 
= 4.79 g of Ag₂O₃S
Answer:
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Explanation:
Erosion can be defined as a geological process which involves the wearing away of earth material and transportation of these material to another location by Natural agents such as wind and water. Erosion involves removal of top soil, rocks and other earth particles by action of wind, glacier and water.
Wind causes erosion by deflation. Deflation is the actual removal of grain of rocks . Generally, it s the lowering of land surface that happens as a result of removal of surface particles(sands grains) by wind. Deflation is usually prevalent in arid areas. This sand can later be picked up and deposited to form sand dunes . Sand dunes are mounds of sand formed by wind . This sands are sheltered by an obstacle. And sand dunes are prevalent in desert and or along the beach. The sand dune grows as sand accumulate.
