Answer:
biological species concept
Explanation:
The biological species concept is the most commonly used and acceptable definition of species, which explains that a group of organisms can be referred to a species if members of the group can interbreed successfully to produce viable offspring that are also fertile. It explains that there tend to be reproduction barriers that would prevent different species of organism from successfully interbreeding. Also, that two organisms have the same appearance, do not necessarily mean they belong to the same species. For example, a horse and a donkey were interbreed to produce an offspring called the mule, but, the mule was found to be infertile. A horse and a donkey are different species, even though they have close appearance.
Answer:
B
Explanation:
The deletion of a single base is the mutation that would most likely impair the production of a protein, because each aminoacid is coded by a triplet of three base pairs. So when one of the bases is deleted, the whole series of triplets is altered so the whole series of aminoacids in the protein would now be different.
Chromosome is to cactus as gene is to a needle.
Attached is the table related to this exercise that I found on the internet.
According to the table, the division with the largest sample was the division II.
Summing up all the individuals from the different divisions we have:
Division I - 22
Division II - 27
Division III - 21
The sample from division II is the largest.
