Answer:
The practice value of serial dilution is done to make an accurate amount of concentration from a dense concentration of cell. In this several process and dilution process is followed.
Explanation:
The process which is followed is taking the sample which is to be diluted of known volume. And after that the dilute or some special solvent is added to make it dilute. The volume of solvent is known.
This process is followed until we get the accurate amount of diluted solution which is to be processed. There is significant value of serial dilution for experiment for other laboratory work. For having a perfect diluted solution, a particular expert of that field is required.
Explanation:
Classification system are system with distribution of classes created according to common relations or affinities.
Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
a video that shows a large river that has penguin populations on both sides
a video that shows penguin species that have different mating dances a video that shows
a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean
Answer:
The right option is a video that shows penguin species that have different mating dances.
Explanation:
Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.
During G1 interphase cell growth happens; a rapid cell growth and production of organelles. Energy releases protein synthesis and specific functions.
