Which term describes the phase of estrus when a female bovine will stand to be mounted?

• A. Standing Heat
• B. Prophase
• C. Biotic
• D. Mortality

Answer: (A)

Standing heat is the phase of the estrous cycle in cattle when the female is receptive to mating and will stand still to be mounted. This behavior marks peak fertility, signaling to breeders the optimal time for insemination or mounting by a bull. Other terms don’t describe mating receptivity: prophase is a stage of cell division, biotic refers to living components in an environment, and mortality means death rate. So the term that best fits the description is standing heat.
