Simple but very simple question. Cellulose.
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)

Answer: Option D
Explanation:
The bacteria can undergo cell differentiation in response to the environmental conditions.
The oxidative stress, antibiotic exposure, stress conditions are some of the external conditions due to which the bacterial cell can respond in the cell differentiation.
The bacterial species can divide based in the conditions in which they are put. So it is true that under stress conditions the bacterial cell can undergo cell differentiation.
<span>Fish that can tolerate a wide range of salinity at some phase in their life-cycle are called euryhaline species. These fish, which include salmon, eels, red drum, striped bass and flounder, can live or survive in wide ranges of salinity, varying from fresh to brackish to marine waters.</span>
