They can be formed by evolution:

A species can't survive in it's environment so it evolves into a more adapted species

Two different species can mate:

A new species can appear from the offspring of two different species.

What is the best estimate for the wing spawn of a butterfly?

The best estimate for the wingspan of a butterfly is typically between 1 to 3 inches, though this can vary depending on the species of butterfly. Some larger species may have wingspans of up to 12 inches.


What will most likely occur if two different plant species compete for the same requirements in an ecosystem?

If two plant species compete for the same requirements in an ecosystem, one species may outcompete the other and dominate the niche. This can lead to a decrease in population or even local extinction of the less competitive species. Over time, competition can result in the evolution of mechanisms to reduce competition, such as partitioning of resources or adaptation to different niches.


Do all species of flowers have the same amount of petals?

No, different species of flowers can have varying numbers of petals. Some flowers have only a few petals, while others may have many. The number of petals can be a distinctive characteristic of a specific flower species.


What are 3 ways to determine the phylogenetic relationship among species?

DNA sequencing: By comparing the genetic sequences of different species, their evolutionary relationships can be inferred based on the similarities and differences in their DNA. Morphological characteristics: Examining the physical traits and structures of species can provide clues about their evolutionary history and how closely related they are. Fossil records: Studying the fossilized remains of species can reveal their evolutionary history and help determine their phylogenetic relationships with other species.


How much blood can a mosquito hold?

A female mosquito can hold around 1-3 milligrams of blood, which is roughly 2-3 times her own body weight. The amount may vary depending on the species of mosquito.
