Anaphase 1 is the correct answer

According to this study, it may have had to do with the deactivation (technically known as “pseudogenization”) of an umami taste receptor gene. Umami is the taste that makes things like meat, soy sauce, and mushrooms extra yummy. Apparently, at some point in panda evolution, the umami receptor became non-functional. Based on how much the gene has changed, the authors calculate that this happened around the same time that pandas started eating bamboo. Whether it’s cause or effect is unclear, although the authors think the switch to bamboo may have happened before the gene was lost. Regardless, the loss of the gene reinforced the panda’s vegetarian diet because it made meat less delicious to the bears.

A type of lymphocyte called NK cell detects cells with abnormal surface proteins and kills them.
<h3>What are lymphocytes?</h3>
One variety of white blood cell is the lymphocyte. They are crucial to the functioning of your immune system, which aids in the body's defense against sickness and infection. An extensive network of immune cells, lymph nodes, lymph tissue, and lymphatic organs makes up your immune system. Immune cells include lymphocytes. The two primary categories of lymphocytes are:
T lymphocytes (T cells): T cells direct your body's immune response and actively hunt down and destroy cancerous and infected cells.
B cells, or B lymphocytes: The B cell produces antibodies. Proteins called antibodies hunt down viruses, bacteria, and other foreign invaders.
Your body's immune system uses lymphocytes to combat cancer and invading viruses and germs (antigens). Your immune system benefits from lymphocytes' assistance in retaining every antigen it encounters. Some lymphocytes develop into memory cells after an encounter. Memory cells detect an antigen and reactbwhen they come into contact with it again. You don't contract illnesses like measles or chickenpox repeatedly because of this. Additionally, it explains why some diseases can be avoided through vaccination.
