Invasive species can enter a habitat in many ways. how were these invasive species introduced?

1.intentional introduction
2.unintentional introduction
3.loss of habitat

a. a species of rats entered a habitat stowed away in a train.

b. a man added invasive water hyacinths to beautify his private lake.

c. a flood prompted many aquatic species to inhabit a new area.

A. 2. Unintentional introduction

B. 1. Intentional introduction

C. 3. Loss of habitat

Step-by-step explanation:

The rats entered the train with no interference from humans, so they were not intended to be there.

The man purposefully introduced water hyacinths to his lake to make it beautiful, so this is intentional.

The flood destroyed their habitats, so they moved to a new area. This invasion was caused by loss of habitat.

Hope this helps!

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
