B.Salinization

C.Cotyledons

D.Salicylic acid

E.Primary consumers

F.Alleles possible for each gene, in their population

When an introduced, invasive species of plant is described as being a strong competitor due to its "aggressive growth," which of the following is likely to be a high value?

A.the number of leaves it produces, to shade its competitors

B.the number of seeds that form, when it reproduces

C.the rate at which its stems grow in length

D.all of these could be high numbers, for an invasive plant species

E.the rate at which individuals reach reproductive age

F.the number of different ways in which it can successfully produce offspring

Answer 1

1) A - Stomata

More number of stoma result in faster transpiration and faster soil drying.

Salinization of soil reduces water availability to the plants whch will maitain soil moisture. Salicylic acid application to soil reduces the salinity of the soil. Primary consumers are microorganisms suppporting the growth of plants and they maintain soil moisture. Genetic mutation helps plants to survive in dry soil conditions.

2) F - the number of different ways in which it can successfully produce offspring.
