You will need a fork, knife, and a spoon for the "predators" to "catch" the "prey". For the "prey" you will need three different
Yakvenalex [24]

In the simulation, the prey type that will avoid capture the most is the beans while the predator that will succeed in capturing the most prey is the spoon.

<h3>What are predator-prey relationships?</h3>

Predator-prey relationships are feeding relationships in which one organism kills and eats another organism for food.

The organism that kills the other is called the predator while the organism that is killed is called the prey.

In the simulation, the prey type that will avoid capture the most is the beans since it had the smallest surface area and size.

The predator that will succeed in capturing the most prey is the spoon because of its hollow nature.

Think about the two words that make up the term reproductive isolation. How do you think reproductive isolation affects the evol
Hitman42 [59]

Answer:

Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.

It may arise from various factors such as:

  • Geographical isolation such as river, mountain, etc
  • Behavioral changes such as mating time or season, mating rituals, mating location etc.
  • Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.
  • Genetic differences.

Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.

These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes

With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.
