<em>Lunar nodes are the locations where the Moon crosses the Earth's orbital plane. Total lunar eclipses happen only when: It is Full Moon. At the same time, the Moon is at (or very near) a lunar node, so the Sun, the Moon, and the Earth are aligned in a straight (or nearly straight) line.

Answer: C. Protein B binds more strongly and Kd =0,3mM Explanation:
• Kd refers to the concentration at which half the kigand binding sites are occupied. • The smaller tge Kd the higher the binding affinity Here, B has a Kd of 0,3mM and A has a Kd of 0,5mM. Thus B has the higher binding affinity due fo smaller Kd
