Based on the illustration, the statement that best explains why the Scotch broom is able to outcompete the native plants in the area would be the specialized seed pods that allow seeds to be dispersed farther and into the less crowded areas.
<h3>Reproductive success</h3>
Different organisms have different ways of behaving to ensure the survival of their propagules or offsprings.
In the case of the Scotch broom, the ability of the pods holding the seeds to burst open and catapult the seeds far away from the parent plant is a reproductive strategy to ensure that their seeds are well dispersed.
By doing so, the propagules of the plant will reach new areas where they do not exist before and as such, able to spread quite quicker than the native plants.

Answer:
plutonium
Explanation:
Since the mass of plutonium is higher than any other one on the chart this means it can withstand more pressure such as being used in architecture
Answer:
Tthe value of
Explanation:
Initial moles of hydrogen peroxide = 1.75 mole
Volume of the container = 25 L
Concentration of a substance is calculated by:
So, concentration of hydrogen peroxide =
The given chemical equation follows:
Initially 0.07 M 0 0
At equilibrium
(0.07-2x) M 2x x
We are given:
Equilibrium moles of hydrogen peroxide = 1.20 mole
Equilibrium concentration of hydrogen peroxide =
Evaluating the value of 'x', we get:
(0.07-2x) M = 0.048 M
x = 0.011 M
So, the equilibrium concentrations of water vapors and oxygen gas are:
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of
