The birds don't eat the food that is provided for them there.
Answer:
The cell organelle, Mitochondria will be very abundant in the wing muscles of a hummingbird.
Explanation:
Mitochondria are known as the powerhouses of the cell. They are are membrane-bound organelles which are found within the cytoplasm of the cells. They are the site for cellular respiration in the cell. The take in nutrients and breaks them down to produce energy in the form of ATP.
Actively respiring tissues and organs possess an abundance of mitochondria which produces the energy required by these tissues and organs.
Since hummingbirds require a tremendous amount of energy to flap their wings so fast, therefore, mitochondria would be very abundant in the wing muscles of a hummingbird.
Answer:
Only the proenzyme contains the added epitope, which is disrupted during activation.
Explanation:
The full-length DNA/ Protein sequence of the human protein of interest should be known before developing the antibody. Therefore the antibody should definitely recognize and bind to the protein of interest even if the antibody was developed from rat tissues. It most likely that the epitope is located on the proenzyme which is disrupted during activation.
