Answer:

B. Monoclonal antibodies are produced from plasma cells

In humans, 23 in males is the only homologous chromosome pair that isn't the same.

Explanation;

-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.

Discuss 2 ways in which efforts to protect species can lead to controversy
Crazy boy [7]

Protection of certain species is a very controversial topic. Many species like the mountain lion or jaguar that are near extinction in certain areas, are threats to human life. Another reason is that they could off set the food chain when they come back and be stonger than ever. For example the mountian lion could eat out the thriving white tail deer population which was struggling because of the mountain lion. And many people rely on white tail deer for food.

Hope this helped :)
