Answer: Enzyme bind to the substrate and increase the reaction rate so catalyze a reaction.
Explanation: Enzymes are the protein molecules and act as a catalyst for a reaction. Enzymes bind to the substrate. A substrate is the reactant molecule of a reaction.
The cycle of enzyme catalysis reaction is as follows :
1. Cycle starts with the binding of enzyme to the substrate, binding takes place at the active site of enzyme.
2. When substrate perfectly fits in active site of enzyme , the binding of enzyme and substrate results in the formation of enzyme-substrate complex.
3. As result of which final product is formed at the end of the reaction.
Answer: D. At the very end of the strand
Answer:
Plants do breathe, just not in the same way as animals... so D
Explanation:
Answer:
D) The porcupine is showing a physical characteristic adaptation and the opossum is showing a behavioral adaptation.
Explanation:
Adaptation, which refers to the ability of an organism to adjust to changes in their external environment in order to survive, is of different types namely: physical/structural, behavioral etc.
- A physical or structural adaptation is a possessed physical characteristics/traits of an organism that enables it adapt.
- A behavioral adaptation is an organisms change in behavioral pattern or responses made to changes in the environment.
According to this question;
- A porcupine is said to have quills on its back which helps protect it from predators. This shows an example of STRUCTURAL or PHYSICAL ADAPTATION, which is the QUILLS it possesses.
- An opossum is said to pretend to be dead and become stiff when threatened. This is an example of BEHAVIORAL ADAPTATION because the opossum responds behaviorally to being threatened.
