Answer:
Activation energy.
Explanation:
Activation energy may be defined as the minimum amount of energy required for the conversion of the reactant to the product. The reaction must have least activation energy to convert the reactant into product.
The reactant must pass this activation energy to convert them into the product. Catalysts are used in the reaction to lowers this activation energy and increases the rate of the chemical energy. The activation energy acts as the thermodynamic barrier that hinders the conversion of substrate into product.
Thus, the correct answer is option (A).
Chytridiomycota is a type of fungi that reproduces sexually and has flagella on its
A) spores
Answer:
Genotype of long winged fly is Ll
Genotype of short winged fly is ll
Explanation:
Given
Allele for long wing trait is "L"
Allele for short wing trait is "l"
When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 
Let us say that the genotype of long winged fly is Ll
and the genotype of short winged fly is ll
The cross between the two will produce following offspring
Ll * ll
Ll, Ll, ll, ll
Out of four off spring two have long wings (Ll)
and the other two have short wings (ll)
Thus the ration of long to short wing offspring is 
i.e
Answer:
Option 2
Explanation:
I did not see the video referenced, but an invasive species is not always brought by people. Furthermore generally there are no limiting factors because it has no natural predators in the environment and often uses up all the resources in that particular environment. Hope this helps!
