What advantage do invasive species of plants have over native species?.
alexandr402 [8]
They are better competitors because they emerge earlier in the spring, grow rapidly, and are impacted by few, if any, natural predators. When invasive plants are allowed to grow unchecked, many native plants and the wildlife species that rely upon them suffer.

PLEASE ANSWER I NEED THE ANSWERS!!!
yKpoI14uk [10]

Answer:

1: 7.8 cm

2: .7 cm

3: 5.55 cm

For the other questions, you have to use a ruler yourself and measure using cm. :)

1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.)

For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!
