Dehydration reactions link monomers together into polymers by releasing water, and hydrolysis breaks polymers into monomers using a water molecule. Monomers are just single unit molecules and polymers are chains of monomers.
This is an image about how hydrolysis and Dehydration work:
Answer:
I am not 100% sure but my best guess would be the object is moving backwards/falling.
Explanation:
The graph shows the position of the object going from almost 9.0 to below zero. There are many situations that could fit this. Such as, something going above and below sea level. OR something moving in front and behind a certain point. My best guess would be moving backward towards an object OR falling from a certain point.
The three germ layers are the endoderm, the ectoderm, and the mesoderm. Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body.
I think the answer here is neurons, the nerve cells
