Let's see which option fits with each characteristic.
Multicellular, or having more than one cell, could be any of these Kingdoms. These are all eukaryotic kingdoms, and eukaryotes cannot be unicellular.
Heterotrophic, or something that cannot produce its own food, can be all of these except Plantae, plants of this kingdom are autotrophic, as they mainly produce their own food (think photosynthesis).
Having a cell wall applies to all of these except Animalia. Animal cells don't need cell walls, as they don't require such a rigid structure as plants. Animals will typically have other supporting structures, such as bones or hydrostatic skeletons.
Being unable to move applies to all of these Kingdoms except Animalia and Protista (which move using their cilia or flagella). Plantae and Fungi don't have the means to move by themselves.
So, the only kingdom that has not been ruled out by one of the criteria is Kingdom Fungi !
Answer:
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. ... The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site.
I believe the correct answer would be : D. Keratin
