Answer:
Bacterial DNA is contained in one circular chromosome, located in the cytoplasm. Eukaryotes have several linear chromosomes. Bacteria also have two additional unique features: a cell wall and flagella. Some bacteria also have a capsule outside the cell wall
Transcription is when DNA segments are copied into RNA.
1. RNA Polymerase bonds to a promoter (Those cool start/stop codons)
2. RNA Polymerase breaks all the hydrogen bonds between the two stands of DNA
3. RNA Polymerase create the pair strand for one of the DNA strands (Uracil instead of Thymine!)
4. Hydrogen bonds break between the DNA strand and RNA strand
5. DNA is zipped back up and RNA either floats around in the Nucleus (if there is one) or exists through a pore
Answer:
Following are the two advantages of endoplasmic reticulum in the cell.
1) Endoplasmic reticulum is an organelle of the cell which is responsible for the production of protein for the cell. This protein is sent to the Golgi apparatus where it is modified and then used by cell where it is needed.
2) Endoplasmic reticulum also helps in removing of toxic substances from the cell. If these toxic substances can't be removed, it causes harm to the cell.

Answer:
The correct answer is - natural selection process does not move simply to an optimized endpoint.
Explanation:
Natural selection is a process of evolution that helps in evolving populations that are adapted to successfully reproduce and survive according to the environment.
Natural selection does not march simply to an optimized endpoint. Natural selection works upon individual organisms that have advantageous characteristics in specific environments. If the environment changes the advantages can become disadvantageous.
Thus, the correct answer is - natural selection process does not move simply to an optimized endpoint.
