Which of the following statements is false? once an invasive species is well-established, it’s virtually impossible to eradicate
VARVARA [1.3K]

The following statement is false: MOST US STATES PROHIBIT THE IMPORTATION OF ANIMAL SPECIES LIKELY TO BECOME INVASIVE IF THEY ESCAPE INTO THE WILD.

Presently, most US states do not have any law, which prohibit people from bringing into the US animal species that are likely to become invasive.

Invasive plant and animals are a great source of problems in America. These species usually destroy habitats and native species, this usually throw the ecological communities out of balance. The government spend  as much as $120 billions every year to control these invasive species.

Explain what it means for a section of DNA to be considered a molecular clock. Be sure to discuss the importance of neutral muta
IceJOKER [234]
  <span>Neutral mutations are neither harmful nor beneficial. 

Therefore, they are invisible to natural selection. (Since they neither improve nor worsen one individual's chances of survival and reproduction over another.) 

However neutral mutations can still spread into the population by just random replications and matings. This is called genetic drift. 

In other words, they are 'silent'. They are mutations that exist and propagate in populations, but seem to have no effect at all. 

The reason they can become important to evolution is that a day can come when they *do* have an effect. In other words, even though an individual mutation may have no immediate effect on survival or reproduction, a *combination* of neutral mutations may provide some new benefit or harm ... at which point natural selection *will* act on that combination.

Describe the path of an impulse associated with lifting your arm. What part of the brain starts this impulse?
timama [110]
Sensory nerves that are part of the peripheral nervous see your arm. Nerve impulses are brought to the brain by interneurons and the brain processes the information and you decide to lift your arm. Nerve impulses from the brain travel again through internuerons and into motor nerves that control the movement of your arm.
