Question

Although different in almost every imaginable respect, agaves (century plants) resemble sockeye salmon in that both are_____________.

a) Iteroparous
b) Semelparous
c) Poikilothermic
d) Viviparous
e) Oviparous

Answer 1

Both agaves and sockeye salmon are semelparous, an adaptive strategy where an organism reproduces just once before dying, which is the common characteristic that they share despite being vastly different in other respects.option b is correct answer.

Step-by-step explanation:

Agaves (century plants) and sockeye salmon are similar in that both are semelparous. Semelparity (or big-bang reproduction) is when an organism reproduces just once in its lifetime, often producing many offspring. Agaves, for instance, will grow for many years without flowering, and then they flower once, produce seeds and die. Sockeye salmon also exhibit this reproductive strategy.

They migrate back to their freshwater birthplace to spawn once and then die shortly after. The opposite of semelparity is iteroparity, where organisms have the capability to reproduce multiple times over their lifespan.

Other reproductive strategies mentioned include poikilothermic, which refers to organisms whose body temperature varies with the environment; viviparity, where offspring develop inside the parent and obtain nourishment directly from the parent's body; and oviparity, where eggs are laid and the offspring's development occurs outside the parent's body.
