Answer:
Golgi apparatus and extracellular matrix
Explanation:Golgi apparatus is the site of modification of synthesized protein transported by cisternae migration from the R.ER. Carbohydrate are either added or removed by the Golgi apparatus at this point. The extracellular matrix which contains storage of macromolecules provided the needed structural and support for the modification.
Therefore if the animal cell lacks ability to add polysaccharides to the protein then , the modification organelle-Golgi apparatus must be missing, and the biochemical support structure (extracellular matrix) for the modification must also be missing.
Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:
A + B + X --> C
A + B + Y --> C
A + B + Z --> C
The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.
I hope it helps, Regards.
Answer:
B
Explanation:
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only. Hence, the correct option is,
Answer:
A tree will get wider by the secondary growth of the cells. This happens when the cell growth of the cambia or lateral meristems causes them to elongate and become primary tissue.
The site below gives a detailed description of secondary growth.
