Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
Answer:
Desmosomes
Explanation:
Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.
Answer:
Water Shapes the Watershed Changes in runoff can increase erosion and sedimentation of the land surface. Excessive runoff can cause downstream flooding and accelerated erosion of the land.
The answers are as follows:
1. <span>An inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate: t</span>his is called competitive inhibitor. A competitive inhibitor will compete with the substrate for the active site of the enzyme and bind to the active site, thus incapacitating the substrate from binding to the active site.
2. An inhibitor binds to a site on the enzyme that is not the active site: this is called non competitive inhibitors. Non competitive inhibitors bind to other site in the enzyme which is not the active site of the enzyme. The binding of the inhibitor changes the conformation of the enzyme as well as the active site, thus making it impossible for the substrate to bind to the enzyme effectively.
3. <span>usually, a(n) inhibitor forms a covalent bond with an amino acid side group within the active site, which prevents the substrate from entering the active site or prevents catalytic activity: this is called irreversible or permanent inhibition. Permanent inhibitors form covalent bonds with the enzyme and prevent substrate from binding to the enzyme.
4. T</span><span>he competitive inhibitor competes with the substrate for the ACTIVE SITE on the enzyme: The active site of an enzyme is the place where the substrate normally bind in order to activate a enzyme. Competitive inhibitors are those inhibitors that compete with the substrate for the active site of the enzyme and prevent the substrate from binding there.
5. W</span><span>hen the noncompetitive inhibitor is bonded to the enzyme, the shape of the ENZYME is distorted. The non competitive inhibitors are those inhibitors that bind to other places in the enzyme instead of the active site. The binding of the non competitive inhibitor usually distort the shape and the conformation of the enzyme thus preventing the substrate from binding to it effectively.
6. E</span><span>nzyme inhibitors disrupt normal interactions between an enzyme and its SUBSTRATE. The principal function of enzyme inhibitor is to prevent the substrate from binding to the appropriate enzyme. This is usually done in the human system in order to regulate the activities of enzymes.</span>
Tissues is the most basic organismal level, <span>which are groups of similar cells that act as a functional unit. </span>
