Answer: 7cm
Explanation:
The surface area of a sphere is calculated by using the formula:
A = 4πr²
Since the surface area is 616cm², using the formula given, the radius will be calculated thus:
A = 4πr²
616 = 4 × 22/7 × r²
616 = 88/7 × r²
Multiply both side by 7/88
616 × 7/88 = 88/7 × 7/88 × r²
49 = r²
r = ✓49
r = 7
The radius is 7cm
The statement 'the body is very complex, so energy moves many different ways' is TRUE about the study of biometrics.
<h3>What is biometrics?</h3>
Biometrics refers to the discipline aimed at measuring different body parts in order to associate this info with specific features.
Moreover, the human body is very complex because it is composed of different organ systems that work together to perform specific functions.
The human body requires to maintain a delicate state of internal equilibrium between energy and matter to perform different physiological processes.

Pick the one with less trans fat, more fiber, and the least sugar. Seeing the phrase "100%" on the packaging usually means whole grains, which can be good as well.
Answer:
Memory cell
Explanation:
Memory cells are long-lived immune cell that can recognize a foreign particle that it previously encountered and consequently fight it by providing or building a faster and stronger response for the immune system.
The memory cells don't respond immediately when it recognizes the foreign particle, but, provides a faster response when it encounters the particle subsequently.
The memory cells are long lived immune cells which means they can live in a system for a vey long period.
There are 2 types of memory cells
Memory B cells and memory T cells.
