The only piece of evidence I have knowledge of is that galaxies are moving apart at alarming rates, and that scientists can sort of "rewind" their movements back to a singular point. Is there any other indisputable evidence that supports the theory of the big bang? BQ: Do Scientists believe that?
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

Since Tameeka is experiencing contractions, this means that she must already be in her third trimester. Contractions usually happen around 38 weeks into the pregnancy. In week 38, the baby is already at the fetal stage which is the third stage of prenatal development.
Answer:
The division of eukaryotic cell is done through various phase known as cell cycle.
Explanation:
The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:
1) G2 Phase; G2 checkpoint ( Interphase stage)
2) Prometaphase (Mitotic Phase)
3) Anaphase (Mitotic Phase)
4) Telophase (Mitotic Phase)
5) cytokinesis (Mitotic Phase)
6) G1 Phase; G1 checkpoint ( Interphase stage)
After G1 phase there would be again S phase in which DNA replication occur.
