Answer:
Describe how oxygen gas is produced during photosynthesis?
Photosynthesis entails the reaction between carbondioxide and water which gives glucose and evolve oxygen
Explanation:
12/44 = 0.2727
(X100)
= 27
( therefore the percent mass of carbon in carbon dioxide is 27%)
C, Proteins is the correct answer
Answer:
The rift valley formed when the crust pulled apart.
Explanation:
The statement that best describes how the Great Rift Valley in Africa formed is that they formed when the crust pulled apart.
- This is geologically known as divergence.
- The Arabian plate and the Nubian/Somali plate are divergent plates.
- They are currently moving apart and away from each other.
- This creates a crack on the earth which is what formed the rift valley in Africa.
- Along such margins, earthquake activities are prominent.
Chemical features like 3 dimensional structure and chemical bonding are responsible for diversity in biomolecules although they are made from simple monomers.
In the case of carbohydrates, both starch and glycogen are made up of glucose monomers yet they differ in the functions which they perform in our body. This difference is because of the chemical bonding and the 3 dimensional structure.
Similarly in protein biomolecules, amino acids act as the monomers but they differ in function due to their 3 dimensional structure. Nucleotides are the building blocks of both RNA and DNA. RNA and DNA perform different functions in the body. DNA stores ad transfers genetic information while RNA is responsible for directly coding for amino acids.
