The answer should be a covalent bond.
The PROCESS by which HAZARD, exposure and risk are determined
Answer:
The catalytic efficiency of the enzyme depends on several factors that can affect the activity of the enzymes. This factors include Temperature, pH, concentration of the substrate, concentration of enzyme and the presence of activators and inhibitors.
Explanation:
The catalytic efficiency of the enzyme depends on several factors that can affect the activity of the enzymes. This factors include Temperature, pH, concentration of the substrate, concentration of enzyme and the presence of activators and inhibitors.
For instance, the pH is an essential factor that has to be maintained properly for the appropriate catalysis by an enzyme. The most favorable pH of most of enzymes present from 6 to 8.
Answer:
The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight.

Cytoskeletal filaments provide the basis for cell movement. For instance, cilia and (eukaryotic) flagella move as a result of microtubules sliding along each other. In fact, cross sections of these tail-like cellular extensions show organized arrays of microtubules.
The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition.
Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a diameter of only about 6 nm, and they are made of a protein called actin. Intermediate filaments, as their name suggests, are mid-sized, with a diameter of about 10 nm. Unlike actin filaments and microtubules, intermediate filaments are constructed from a number of different subunit proteins.
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.
