We will solve assuming the formula is:
 h(t)=-14t^2+148t+7.8, where h is the height of the ball in feet and t is the time in seconds since it is pitched
We need to find t, t > 0, such that h(t) = 0
-14t^2+148t+7.8 = 0


t = 10.6 s
The ball will stay in the air for 10.6 seconds.

A type of lymphocyte called a(n) ________ detects cells with abnormal surface proteins and kills them.
kirill [66]

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.
