The most accurate response would be between A and D.
The answer is; C
Rhizoids are analogous to roots in vascular plants. They anchor the gametophyte of the moss into the substrate. The rhizoid is also significant in absorbing nutrient from the substrate just like roots. While roots of vascular plants are multicellular, rhizoids may be unicellular or multicellular. Unlike in roots where water is absorbed and passes through the roots up the plant, in rhizoids, water is carried by capillary action in between the rhizoid threads.
They had to change they way they live which is quite difficult it is like you going to a new school in a new state and not being used to anyone
It speeds up the reaction....this makes the reactants turn into products more quicker and makes it stop much slower. Below is a graph for a regular reaction and a reaction with enzymes. An enzyme is a type of catalyst.
