Answer:
Structurally, proteins are different from carbohydrates because all proteins contain nitrogen (option C).
Explanation:
The basis of the chemical composition of proteins is carbon, hydrogen, oxygen and nitrogen, so all proteins have nitrogen in their structure. Some proteins also possess phosphorus and sulfur atoms, among others.
Proteins are biomolecules formed by the union of multiple amino acids through carboxyl-amino bonds, called petidic bonds. Their content of nitrogen and other atoms in their structure is what makes them different from carbohydrates.
The other options are not possible because:
- <em>Only some proteins contain </em><u><em>iron</em></u><em> in their composition.</em>
- <u><em>Potassium and helium</em></u><em> are not part of the protein structure.
</em>
Answer:
A) Apt is created in the light reactions and is used in the Calvin cycle
Answer:
1. an eclipse of the Sun
2. state (phase) of matter
3. 5.0 g/cm3
Explanation:
1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.
2. Considering the following groups: Group A: water, aluminum, water vapor
Group B: gasoline, ice, air
Group C: alcohol, iron, oxygen
One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.
This shows that the STATE (PHASE) OF MATTER was the basis of classification.
3.
Answer:
The correct answer is The process of photosynthesis is energy storing reaction because the process converts light energy into chemical energy which is stored in the bonds of glucose.
Explanation:
Photosynthesis is an important pathway occur in the mesophyll tissue of leaves of plants . Photosynthesis helps in formation of glucose molecule that is stored as polysaccharide starch inside the plant"s body.
During photosynthesis light energy is captured from sun by the antenna complex of photosystem then the light energy is transferred to the reaction center for its conversion into chemical energy in form of ATP molrcules.
The so formed ATP molecules helps in the biosynthesis of glucose by various enzyme catalyzed reactions.
