You cannot put your hand on a solid table because the particles are close together and in a fixed position. This is because the atoms of a solid are not like liquid, gas, and plasma. The particles are too condensed to move around an opposing force.
The four bases in DNA are adenine, cytosine, guanine, and thymine.
<span>These four are divided into two groups. The pyrimidines, the single-ring nitrogenous bases, is where thymine and cytosine is included. The purines, the double-ring nitrogenous bases, includes adenine and guanine. </span>
<span>Cytosine will only bond with guanine; they form three hydrogen bonds. Adenine will only bond with thymine forming two hydrogen bonds.</span>

The correct answer is option A.
Explanation:
The lymph node is a small bean-like structure that filters substances that move through the lymphatic pathway with the lymphatic fluid. Lymph nodes are present on different site in the human body.

Thus, the correct answer is option A.
Answer:
318,6 ms-1
Explanation:
Como sabemos que la relación entre la velocidad del sonido en el aire y la temperatura viene dada por;
V = 331√T / 273
Dónde;
V = velocidad del sonido
T = temperatura en kelvin = (-20) + 273 = 253 K
V = 331√253 / 273
V = 318,6 ms-1
