I would say (A) because it allows the bacteria (bacteria X) to be exposed to the control condition and the experimental condition so that a cause-effect relationship can be established. Here, the control condition would be the darkened area and the experimental condition would be the lightened area.
Nucleus controls the cell, it tells the cell what to do, similar to a brain. Rough ER or Ribosome ER creates the proteins in the cell. Golgi Apparatus packages macromolecules like lipids and proteins for transport.
Organs, cells with the same function make up tissue and tissue makes up the organ
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.
The answer to this question would be more movement.
The amphiarthrodial joint is a joint that you will found in the rib cage. This joint doesn't have a synovial cavity and only allow a little movement.
But synarthrodial joints movement is practically zero. The example for <span>synarthrodial joint would be suture in your skull. Skull joint in adult can't move so its volume can't be changed.</span>
