Nonnative invasive species are often a threat to native species because they

a. typically grow larger than other plants.

b. are not susceptible to any diseases.

c. are parasitic.

d. do not have natural enemies in their new location.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Expert Solution & Answer

Summary Introduction

Introduction:

The invasive species can be defined as the plant, animal or fungus that is not the natural habitat of a specific location; however, they are introduced and spread to a greater extent. This greater expansion leads to damage to the environment and a threat to the native species.

Answer to Problem 1U

Correct answer:

The non-native invasive species do not have enemies in their new location and this account for threat to the native species. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

The non-native invasive species poses more threat to the invasive species because the native species have natural attackers and enemies. The non-native invasive species are new to the location and hence, there is no threat of attackers for them. They possess a more risk because they lack natural predators in the new location.

Option d. is given as “do not have natural enemies in their new location”.

As, “the non-native invasive plants do not have any natural predators in their new environment, they possess a threat to the native species”, is the right answer.

Hence, option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “typically grow larger than other plants”.

The size of the non-native invasive species does not possess a threat to the native species. So, it is a wrong answer.

Option b. is given as “are not susceptible to any diseases”.

The non native invasive species are the normal living organisms and they suffer from diseases. So, it is a wrong answer.

Option c. is given as “are parasitic”.

The non-native invasive species are not parasitic rather most of them are free-living. So, it is a wrong answer.

Hence, options a., b., and c. are incorrect.

Conclusion

The non-native invasive species are the plants, animals or fungus, which are introduced into a new environment and they are not the natural inhabitants of that location. They lack natural enemies in their new environment and hence, their growth rate are very high.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
