Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
A protein's secondary structure is characterized by beta pleated sheets and alpha helices; the primary structure of a protein is the order of amino acids in a polypeptide, which is coded for the DNA of a gene. the secondary structure itself results from Hydrogen bonds, where the electronegative nitrogen and O2 atoms impart the hydrogen atoms with a semi positive charge.

Answer:
It will die.
Explanation:
Fish need functional gills to live.
Van der Waals interactions may result when electrons are not symmetrically distributed in a molecule. Van der Waals forces, in physical chemistry are essentially
associated with the name of a Dutch researcher Johannes Diderik van der Waals
and indicate the separation of dependent interactions among particles and
atoms.
