Answer:
Explanation:
1: Pioneer species are the first to colonize: During primary succession in lava on Maui, Hawaii, succulent plants are the pioneer species. After weathering breaks down the lava into the soil, the plants are able to take root. These plants will help to further change the soil by adding nutrients to it.
The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.
C is the answer did y get it right
Answer:
Partial pressure of He = 73 kPa
Explanation:
Given:
Total pressure = 125 kPa
Partial pressure of Ne = 31 kPa
Partial pressure of Kr = 21 kPa
Find:
Partial pressure of He
Computation:
Total pressure = Partial pressure of Ne + Partial pressure of Kr + Partial pressure of He
125 kPa = 31 kPa + 21 kPa + Partial pressure of He
Partial pressure of He = 73 kPa
longitudinal wave.... is the right answer
