Because enzymes connect to their substrate through a lock-and-key system, where the shape of the substrate and the enzyme has to fit like puzzle pieces. Then only the enzymatic reaction can occur.
Answer:
The suitable words for fill in the blanks will be -
- embryo
- flippers
- disappear
- off
- genetic
Explanation:
Examining a dolphin embryo highlights its evolutionary history. Early in dolphin development, both fore and hind limb buds form. While the forelimb buds continue to develop into flippers, the hind limb buds disappear. The genes that are normally active in the hind limb buds of four-limbed animals are turned off. A genetic change leading to the silencing of a trait during development may have been an important milestone in cetacean evolution.

1. Establish routines. Young children thrive on them, and they make perfect fodder for enhancing your child's memory.
2. Play memory games. Ask questions when you're out and about. For example, if you're passing a friend's house, ask, "Who lives there?" Games like this give children experience in recalling information.
3. Demonstrate how to perform tasks. Babies model their parents' actions. If you want your child to learn how to do something, such as stack one block on another, show him how and then give him a turn.
4. Talk with your child about her experiences. Focus on events that resonated strongly with her, such as a trip to the zoo. As she gets a little older, help her make stories out of her recollections.
