<span>3) What is the resulting formula unit when strontium (Sr) and phosphorus (P) bond?
Strontium (Sr) wants to lose two (2) electrons, and phosphorus (P) wants to gain three (3). By using the criss-cross method, if you flip the 2 and 3 to the opposite elements, you will end up with the formula Sr3P2.</span>

A normal chromosome and its homolog carrying an inversion are given. The dot (•) represents the centromere. Normal: M N • O P Q
AlladinOne [14]

Answer:

Pericentric, inversion loop.

Explanation:

Chromosomal inversion may be defined as the rearrangement of chromosome that may get reversed and attached. Two main types of inversion are pericentric inversion and paracentric inversion.

The pericentric inversion involves the inversion of chromsome and centromere is involved in this inversion. M Q P O • N R S T , in this case centromere is present and shows the pericentric inversion. The structure that forms during the synapsis is known as inversion loop.

Thus, the answer is pericentric, inversion loop.
