Answer:
a. do not immediately increase in number when placed in a culture
Explanation:
When bacteria placed in a new culture it shows a pattern of growth which is known as sigmoid growth. It has four phases lag, log, stationary, and death.
The lag phase occurs because bacteria do not start dividing immediately just after the placed in the new culture media because bacteria first adapt to the new environment and prepare enzymes needed for metabolizing the new substrate.
As the bacteria pass this lag phase it starts to divide at an exponential rate. Therefore it is true that most bacteria do not increase in number immediately after placed in a new culture.
Interphase is when the cell grows and duplicates chromosomes. This is important for the cell to divide, because otherwise, the cell would shrink everytime it divided and would not have a sufficient amount of DNA
The correct answer is radial symmetry.
This means that there's a central axis around which they are formed, which is similar to how starfish or tulips grow. Similarly put, it's like cutting a pie or a pizza through the axis and getting the same pieces.
Answer:
We have two sets of chromosomes because we're diploid organisms: the most obvious function of this is that two parents can mix and match their genes in (figurative) hopes of getting some optimum combination in at least some of their offspring.
Explanation: Parents had the smash and their genes were passed on.
