Answer:
a. Memory T cells
Explanation:
Memory T cells are actually the antigen-specific T cells that remain long-term after an infection has been eliminated. These memory T cells are quickly converted into large numbers of effector T cells upon reexposure to the specific invading antigen, thus providing a rapid response to past infection that has been experienced before
Answer:
Force that the output plunger applies to the car; F2 = 3888N
Explanation:
For a hydraulic device, the relationship between the force and the area using Pascal's principle is;
F1/A1 = F2/A2
Where;
F1 is force applied to the input piston
F2 is force that the output plunger applies to the car
A1 is Area of input piston
A2 is area of larger piston
We are given;
R2/R1 = 9
So,R2 = 9R1
F1 = 48N
Area of input piston;
A1 = π(R1)²
Area of output piston;
A2 = π(9R1)²
Since, (F1/A1) = (F2/A2)
Thus;
F1/(π(R1)²) = F2/(π(9R1)²)
If we simplify, π(R1)² will cancel out to give;
F1 = F2/9²
Thus;
F2 = 9² x F1
Plugging in 48N for F1, we have;
F2 = 9² x 48
F2 = 81 x 48
F2 = 3888N
Answer:
1372
Explanation:
use the speed formula
Speed=wavelength x frequency
Answer:
Cell Membrane
Explanation:
The cell membrane controls what goes in and out of a cell, and keeps it shape, much like a city limit.
