The patellar region has a reflex (when the doctor hits your knee with that little rubber hammer and you kick your leg). Any reflex protects us from harmful things. The kneecap also covers and protects the anterior articular surface of the knee joint.
Answer:
The correct answer will be option- binds to its specific amino acid in the active site of an aminoacyl-tRNA synthetase
Explanation:
Transfer RNA or tRNA is the RNA which scans the mRNA and adds specific amino acid to the nascent peptide to form a protein molecule.
There are many specific types of tRNA which brings specific amino acid to the growing peptide.
The tRNA binds the specific amino acid in a reaction catalyzed by the aminoacyl-tRNA synthetase which contains an active site to bind tRNA and amino acid. The reactions get their energy from the breakdown of the ATP molecule. The reactions bind the specific amino acids in the specific synthetase enzyme with tRNA.
Thus, the selected options are the correct answer.
Answer:
Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.

Answer:
Step 1: A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis.
Step 2: A caterpillar gets the carbon by eating the tree's leaves.
Step 3: A bird gets the carbon by eating the caterpillar.
Step 4: The bird flies into a building and dies instantly. It falls to the ground.
Step 5: The bird decomposes and the carbon returns to the atmosphere.
