Answer:  That translates to "Which is the potential for action" in English.  I hope that is what you were looking for as I have nothing else to base your question off of, as you only put a line of Spanish as your question.

Which pair of terms most accurately describes life history traits for a stable population of wolves? A. semelparous; r -selected
Lera25 [3.4K]

The correct option is (D) iteroparous; K -selected

Iteroparous organisms are the organisms that reproduce multiple times.

<h3>What is Semelparity and Iteroparity?</h3>
  • Semelparity and iteroparity are the two different reproductive strategies available to living beings.
  • Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
  • Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
  • There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.

Answer:

Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.

Part B:

The process 1 is meiosis. The process 3 is development by mitosis.

The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.

The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
