<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
- Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
The weak bonds are called hydrogen bonds and they are used to connect the hydrogen atom to oxygen atom in order to share electrons.
Answer:
(C) Competitive inhibition
Explanation:
When a substrate competes with and inhibitor, what they are actually doing is competing by the active site of the enzyme. In terms of probabilities, when there is much more of one molecule of X than its competitor Y, it is more likely for any of the molecules of X to reach the active site of the enzyme than for any of the molecules of Y.
Then is one would like to reduce the effects of an inhibitor reversible bonded to an enzyme, one possibility is to increase the concentration of a substrate (which in turn means that there will be a higher relative number of its molecules in the media), increasing the probability to meet the active site of the enzyme and as a result displacing the inhibitor (assuming it not increased as well).
