When a cat drops from a tree to the ground, the cat is transforming chemical energy attained from the food into kinetic energy. The later energy is used by the living species when they are performing locomotion.
When a cat feeds on a mouse, the mouse will undergo through the process of digestion resulting in the formation of chemical energy. Thus, the food consumed by the cat will get transformed into chemical energy that can be utilized by the cat to perform its usual activities.
Answer: Both the mouse and human beings are encoding the proteins having similar functions.
Explanation:
The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.
Option A is incorrect because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.
Option B is incorrect because amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.
