the answer is the second one how appearance of an organism and its structure
Answer:
A) The loop did not cross into quadrant 1 when streaking quadrant 2
Explanation:
The streak for isolation technique is a method used to get isolated bacterial colonies. This technique consists of, in a petri dish with culture medium, where, with the help of an inoculation loop, the bacteria are scratched on one side of the dish. This side is called the first quadrant. This inoculation loop must then cross with the first quadrant and be dragged to the second quadrant, where new lines must be made. This allows a part of the bacteria from the first quadrant to be carried over to the second. The inoculation loop must cross the second quadrant again to inoculate the third quadrant, and so on.
In this case, we can see that for bacterial colonies to grow in all quadrants, it is essential that the loop crosses in the first quadrant to cross out the second quadrant. If not, only the first quadrant will have bacterial colonies.
The example of a scientist studying Darwin's ideas is that of archaeologists uncover, catalog, and compare fossils of marine life.
Darwin's ideas stated that the traits that favor the survival of a species are passed on by natural selection. Natural selection puts environmental pressures on the species, such as predators, which removes the less suited genes from the gene pool. An archaeologist will study this as he or she will observe the changes that will have taken place in the species over time.<span />
