Many closely related species of ducks have different courtship dances that are performed to solidify a pair-bond. If you were to
damaskus [11]

Answer:

I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.  

Explanation:

The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.

Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.

A species of birds entered a nonnative habitat and is now considered an invasive species. What’s the most likely effect this spe
Lady bird [3.3K]

Answer:

The native species will more than likely be eradicated or they might learn to co-habitate.

Explanation:

The nonnative bird species will compete for resources with other species that share the same resource. Depending on the stronger animal or the bird that is more fit for that area to survive, depends on whether the native species will be effected or the nonnative species will be affected. If the invasive species has more tools to enhance their survival, then they will likely eradicate the native species. the same can be said for the Native species.

xenn [34]

Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.

At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.

High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
