Answer: They possess different functional groups.
Explanation:
Organic compounds are molecules composed of many carbon atoms bound together and in turn bound to hydrogen atoms. These molecules form the lipids, proteins, carbohydrates and nucleic acids that constitute all living beings. The reason why there is so much variety of organic molecules is because each one can have one or several <u>functional groups in different positions, which gives them unique properties.</u>
So a functional group is a group of atoms linked in a certain way, which present a specific physical-chemical structure and properties that characterise the organic compounds that contain them.
Examples are:
- Lipids: A carboxylic acid
- Proteins: A carboxyl group and an amino group
- Carbohydrates: An aldehyde or ketone group
- Nucleic acids, Nucleotides: A phosphate group
Answer:
They can't because they are complete by themselves, i.e. independent of each other to survive, unlike higher animals and plants.
C: Mountains.
Explanation: The two plates collide and push up against each other, forming the mountains
Answer:
can ,synthesize specific proteins
Explanation:
Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.
They are transported in the circulatory system of the body
The action of hormones can be seen after the hormone has bound to its specific receptor found inside the cell.
For instance, steroid hormone and the thyroid hormones can pass through the plasma membrane to their receptors inside the cells.
When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.
