Two species of tree frogs that live sympatrically in the northeastern United States differ in ploidy: Hyla chrysoscelis is diplo

id, and Hyla versicolor is tetraploid. The frogs are identical in appearance, but their mating calls, which females use to find mates, differ. Which difference most likely evolved first?

Answer:

The correct answer is - polyploidy.

Explanation:

Speciation can be two types allopatric and sympatric speciation. Sympatric speciation is the process of speciation is developing the new species that diverged from the common ancestral species while the ancestral and developed species both can share the same place or geological area. The main cause of such speciation is due to the change in their genetic level more than environmental conditions.

In this case, the frog's species show differences in their ploidy level as well as their mating call but polyploidy is the most likely the difference that evolved first rather than females call for mating.

Thus, the correct answer is - polyploidy.

Mandarinka [93]

Answer:

The correct answer is -

1. Based on height he is 50% and height he is 25%

2. The nutritional needs are normal due to the constant percentage in both height and weight throughout.

Explanation:

By the reference of the chart of growth rate presented by CDC,

These informations can be found-

Weight :

A= 50%

B=50%

C=50-75%

Height :

D=10-25%

E=25%

F=25%

Then the percentage of height by weight ratio

Height by weight%:

G=75-90%

H=75-90%

I=75-90%

Thus, the correct answer is -

1. Based on height he is 50% and height he is 25%

2. The nutritional needs are normal due to the constant percentage in both height and weight throughout.

FinnZ [79.3K]

Answer:

well from what i can see based on the data in the graph is that, since the accidental introduction of species 3 the population of the other 2 species has decreased quite a bit. While you can also observe that the population of population 3 continues to grow.

This suggests 3 possibilities to me

possibility 1. species 3 is consuming leaves just like the other 2 species causing a scarcity in food.

possibility 2. species 3 is consuming the other 2 species causing the decrease in population.

possibility 3. species 3 and the other species may be fighting over shelter, food, or water, causing more lizard fatalities.
