Answer: This is called allopatric speciation. The species continue to evolve in the own way, adapting to their different conditions. The eventually become two different species adapted to each environment.
Answer:
Photosynthesis relies on sun, water, and CO2 for it to make food. When there are lower levels of either, the organism carrying out photosynthesis can't make as much glucose and oxygen. This in turn harms the organism.
Answer: It is a selective and differential medium.
Explanation: Selective medium is used to select the growth of certain bacteria whilst inhibiting the growth of another by preparing a medium with ingredients that will only select a specific growth of intended microbe. When closely related bacteria had been selected, they can further be differentiated by the way they utilize the medium. In this case staphylococcus aureus was first selected using sodium chloride with which only this bacteria can tolerate i.e halophilic (strives in salty environment). It was also further differentiated by its ability to ferment sugars changing the colour of the pH indicator chemical.
DNA unwinding begins at the Origin of replication.
Answer: A) Atom, Molecule, Cell
Explanation: An atom is the smallest unit of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. And molecules join together to form cells.
