Answer:
Chitin
Explanation:
This glucose derivative is in fact the main building block of cell walls in not only arthropods (including the shrimp), but also fungi and insects, and also has a structural function in the scales of fish. The most similar commonly-known substance in terms of function is keratin, which makes up our hair and nails.
Answer:
The correct answer is option d) "head-on".
Explanation:
In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.
Answer:
Rate of product formation is linear and [S] has not been lowered significantly.
Explanation:
The rate of enzyme-catalyzed reactions is affected by several factors, the contraction of substrates [S] is one of them. The substrate concentration keeps on changing as the reaction proceeds. This is why the reaction rate is measured at the initial stages of reactions when the substrate concentration [S] is much greater than the concentration of the enzyme. It is called the initial rate or initial velocity.
Under the conditions of higher substrate concentration and relatively much lower enzyme concentrations, only a few molecules of substrates are being converted into product. At a relatively higher substrate concentration, the rate of product formation increases linearly.
