spirillum
the bones are rigid --------- I think a better way to answer this is they are rigid, but both curved and straight. Have you ever seen a picture of the femur, the pelvis, or the scapula? What about the clavicle? These bones, as all bones are, are rigid. They hold their shape (unlike the cartilage of the ear or nose) but are curved. A rigid straight bone could be named as the phalanges, or the humerus (MAYBE). I mean, even the radius and ulna are curved a small amount.
The cell wall is a rigid supporting structure.
Coccus or cocci
Plant cells have a rigid cell wall made of cellulose that provides structural support and rigidity, whereas animal cells do not have a cell wall and rely on other structural components like the cytoskeleton for support. This difference in cell wall composition is what makes plant cells rigid and animal cells flexible.
Tetanus (aka Lock Jaw) is caused by the bacterium Clostridium tetani. More specifically, it is the neurotoxin released by lysing bacteria (Tetanospasmin) that is responsible for the rigid paralysis.
The rigid helix structure is found in spirochetes, which are spiral-shaped bacteria characterized by their flexible, corkscrew-like shape that allows them to move in a corkscrew motion. Spirilla, on the other hand, are spiral-shaped bacteria with a more rigid structure that do not exhibit the same flexible helical shape as spirochetes.
one is rigid and the other is flexible :)
What is the difference between rigid and flexible coupling.
A lightweight and rigid.
rigid
The answer to the analogy "rigid is to flexible" is "strict is to lenient." Just as rigid and flexible are opposite in terms of stiffness, strict and lenient are opposite in terms of severity.
The word "pliable" completes the analogy. Rigid is to flexible as inflexible is to pliable.
No, flexible and rigid are not forces. They describe the ability of an object to bend or deform (flexible) or to resist bending or deformation (rigid). Examples of forces include gravity, friction, and tension.
Rigid
It has a rigid skeleton but the body is flexible.
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.
