A substance that can be used or prepared for use as food
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
The correct answer is C. Tissue
Explanation:
In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.
the answer to your question is the amount of time and the effect it has on each material as well as the fact that the nitrogen cannot change it is an unchangeable variable whereas everything else the time, the substance of the subject, the possible formation of nodules can change without changing the identity of the experiment itself otherwise, you have a dependent variable. I hope this helps :-)
