The next bone healing stage is called the hard callus<span> stage.This transformation occurs when bone forming cells called osteoblasts travel across the </span><span>soft callus.</span>
If i remember correctly they should be adenine (A), thymine (T), guanine (G) and cytosine (C). i hope this helps. sorry if they arent all correct.
Answer:
The stage of cellular respiration which yields the most ATP is the electron transport chain.
Explanation:
Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).
The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:
-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)
-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)
