Positive applications for allelotoxin is that it prevents plants from enduring any type of competition with other species.
<h3>What is Allelopathy?</h3>
This is the process in which a plant inhibits the growth of another through a secretion of a chemical which is referred to as allelotoxin.
This technique however reduces biodiversity which isn't ideal so as to prevent organisms from going extinct and also reduces adaptation or evolution due to the reduced or non growth of the plant species which are affected.
A common example is the sorghum plant preventing of the growth of weeds thereby resulting in the most appropriate choices for the positive applications of allelotoxin.

Answer:
412.1kJ
Explanation:
For the reaction , from the question -
4Fe (s) + 3O₂ (g) → 2Fe₂O₃ (s)
Δ Hrxn = Δ H°f (products) - Δ H°f (reactants)
In case the compound is in its standard state , enthalphy of formation is zero
Hence ,
for the above reaction ,
ΔHrxn =( 2 * Δ H° (Fe₂O₃ )) - [ ( 4 *Δ H° Fe ) + (3 * Δ H° O₂ )]
The value for Δ H°(Fe₂O₃ ) = - 824.2kJ/mol
Δ H° Fe = 0
Δ H° O₂ = 0
Putting in the above equation ,
ΔH rxn = ( 2 * Δ H° (Fe₂O₃ )) - 0
ΔHrxn = 2× - 824.2 kJ / mol = - 1648.4 kJ/mol
- 1648.4 kJ/mol , this much heat is released by the buring of 4 mol of Fe.
Hence ,
for 1 mol of Fe ,
- 1648.4 kJ/mol / 4 = 412.1kJ
One difference is that some animals are polyp and some are medusa.
The other difference is that some animals have medusa in their life or polp in their life cycle.
Hope these two differences helps :D
Answer:
2.567
Explanation:
To change milliliters into liters you divide by 1000
So when you divide 2567 by 1000 you get 2.567
