Answer:
According to Darwin's theory of evolution, new species evolved as a result of natural selection.
Explanation:
- Darwin proposed that speciation could readily occur through the prolonged action of Natural selection.
- Natural selection allows the 'survival of the fittest' i.e. a more fit organism will have a better chance of survival than the less fit one.
- The result of Natural selection could be positive,negative or balancing.
- Evolutionary process in which the genetic changes confer a higher fitness to increase frequency of the organism over time in population is called positive selection.
- Evolutionary process in which genetic changes decreases the organism's fitness resulting in its disappearance from the population is called Negative selection.
- It may happen that a mutation benefits hetero-zygotes but not homo-zygotes and alleles maintain a intermediate frequency in population.This evolutionary process is called balancing selection.
Answer:
Protein synthesis in rough endoplasmic reticulum (RER) and packaging in smooth endoplasmic reticulum (SER)
Explanation:
Intracellular Protein Transport:
- After transcription in the nucleus, the mRNA is translocated from the nucleus to the ribosomes attached to the rough endoplasmic reticulum (RER). The RER is the site of the biosynthesis of proteins.
- The process of translation of mRNA sequence into amino acid sequence takes place in the RER.
- The newly synthesized protein is then packaged into vesicles in the SER and transported to the Golgi complex.
- The Golgi complex is the cell's packaging department. It packages proteins into transport vesicles for intra and extracellular protein transport.

Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.
Explanation:
Binary fission and mitosis can be viewed as the same principle of asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.
Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.
