When biofilms bond together sedimentary grains, they can form stromatolites.
A rhizoid<span> (such as is found on the gametophytes of bryophytes or ferns) is basically just a filament that anchors the plant to the ground. A </span>root<span>, on the other hand, is a sophisticated structure containing many differentlayers including vascular tissue, playing a key role in water and nutrient uptake</span>
The terminal cisternae releases calcium ion
The terminal cisternae act as calcium storage sites. The calcium ions stored in the terminal cisternae are essential in muscle contraction. The calcium release unit of muscle consists of terminal cisternae of the sarcoplasmic reticulum and it is adjacent transverse or T- tubule that is the invaginated part of the surface membrane.
True is the correct answer
<span>c. active site because </span>the shape of the substrate should compliment that of the active site. The enzyme changes the shape of its active site slightly as the substrate binds which forms the induced fit model.
