<u> Bacterial growth curve-</u>
The phase in the bacterial growth curve which is defined by zero net growth due to a lack of nutrients and excessive waste products being present is the death phase of the growth curve.
<u>Phases of the bacterial growth curve-</u>
The bacterial growth curve is a curve that depicts the number of viable live cells in a bacterial culture over a span of time. This growth curve has four very distinct phases, which are- lag phase, log phase, stationary phase, death phase.
- Lag phase- The first phase which is the period of metabolic growth rather than division of cells.
- Log phase- The second phase where the cells are dividing and increasing in numbers.
- Stationary phase- The third phase where the bacterial cells reach a stagnant period and stop dividing due to the lack of nutrients.
- Death phase- The last phase where there is no metabolic growth or cellular division. The culture is filled with metabolic wastes from the lysis of cells.

The answer is from another male zygote or his male father.
Yes it can !!!!!!!!!!!!!!! just did that got it right
<span>The correct answer is C.stability is genetic and cannot be improved. This is incorrect. Just think of when you ride a bike, it's not a genetic thing and anyone can learn it if they learn how to balance their center of gravity and their movement. It's not a genetic thing so only a few chosen people can ride a bike.</span>
the correct answer is A- Reproductive isolation occurred through behavioral isolation
A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.
In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.
