C. They count steps during a workout, is the correct answer
The orca's body, like that of other living creatures, is made up of cells. Eukaryotic cells are seen in orca whales. Cells of this sort can be found in all mammals. A nucleus is found in eukaryotic cells. The nucleus is the cell's brain. The nucleus directs the activity of the cell in the same way as the human brain directs the movements of the body. DNA is found in the nucleus. The blueprint for an animal's body is DNA. The genetic code is carried by DNA. The messenger RNA transports the DNA information to the ribosome, which is where proteins are produced. Organelles, which serve as miniature organs with various functions, are found in every cell. Killer whales have 44 chromosomes, and an outstanding banding investigation on six killer whales revealed significant C-band variation. Because they have complex cells, killer whales are classified as Eukaryotes. Membrane-bound organelles, including a nucleus, are found in their cells.
Im pretty sure this is how it works:
you burn yourself,
immediately, you jump back because obviously, it hurts
That part (the jump back) is your skeletal and muscular working together to move you away from the danger
This is called the fight or flight response.
This time, you took flight from the danger. hop this helped a bit, if not, i can edit and add more for ya :)
