Ribosomes are like a factory, they create proteins that make up many parts of the human body. Without Ribosomes you wouldn't have hair, skin and even fingernails.
If s plant cell is placed in a hypertonic solution the plant cells lose water and hence the rigidity pressure by plasmolysis pressure decreases to the point where the protoplasm of the cells peel away from the cell wall and it leaves gps between the cell wall and membrane making the plant cell flaccid.
True.
It is easier since there are a lot of theories that could sum up and provide evidence to support that an object has life than life itself.
One popular theory is the cell theory which states that all organism is made up of cells, cell that came from those pre-existing cells, and reproduce by those cells themselves.
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>
Cell bio is important so that we can know more about cells and how they function
