Consider the picture. This fact shows that parasites can alter host behavior. What is correct about behaviour changing from host?
Adult female Plagiorhynchus lays eggs within the intestines of infected birds.
A terrestrial isopod eats the feces of an infected bird.
The eggs of Plagiorhynchus hatch within a few hours, they develop into a mature larva in 60-65 days.
Infected isopods leave sheltered areas and wander in the open.
Consider the picture. This fact shows that parasites can alter host behavior. What is correct about behaviour changing from host?
Rust fungus Puccinia monoica manipulates growth of host mustard plants (Arabis sp.).
Puccinia infects Arabis rosettes and invades actively dividing meristemic tissue.
Rosettes rapidly elongate and become topped by a cluster of bright yellow leaves.
The pseudo-flowers of infected rosettes are produced by various fungal structures, including spermogonia containing spermatia (fungal reproductive cells).
Consider the picture. This fact shows that parasites (rust fungus Puccinia monoica) can alter host behavior (mustard plants (Arabis sp.). What is negative effect for host?
The Arabis sp. that survive attack by Puccinia may go on to flower but none form seeds.
The Arabis sp. that survive attack by Puccinia can not produce leaves.
The Arabis sp. that survive attack by Puccinia may go on to apical bud but none form flowers.
The Arabis sp. that survive attack by Puccinia can produce seeds without flowers first.
Consider the picture. This fact shows that exploitation with competition in flour beetles (Tribolium). But, the presence of a protozoan parasite (Adeline tribolii) influences competition. What is the effect?
Tribolium confusum is usually the strongest competitor, but with the presence of Adelina sp., Tribolium castaneum becomes strongest competitor.
Tribolium castaneum is usually the strongest competitor, but with the presence of Adelina sp., Tribolium confusum becomes strongest competitor.
Tribolium castaneum and Tribolium confusum becomes equal strong competitor as the the effect the presence of Adelina sp.
Tribolium castaneum and Tribolium confusum becomes destroyed as the the effect the presence of Adelina sp.
Consider the picture. Mid 1800’s: prickly pear cactus Opuntia stricta was introduced to Australia. Established populations in the wild. Government asked for assistance in control. What is organism type which can reduce 3 orders of magnitude in 2 years?

Mycorrhizal fungi appear to improve the ability of many plant to extract soil water by giving more extensive contact with moisture in the roting zone and provide extra surface area for absorbing water.
