DDT is an insecticide that can remain in the bodies of insects and then is transferred to the fat of the animals who eat the insects. Based on what you know about bioaccumulation, who would be most impacted by DDT?

birds who eat the insects (trophic level 2)

small mammals who eat the insects (trophic level 2)

birds of prey who eat small mammals and other birds (trophic level 3)

all are equally affected

Bees, ants, and other social insects are able to detect and will remove dead organisms from their colony. Scientists have analyzed decaying insects and found they give off compounds, mostly oleic acid and linoleic acid - as they decay. You know that social insects display some of the most complex behaviors in response to environmental stimuli of any other animal groups. In lab today, you learned that it is possible to explain behaviors based on anthropomorphic causes, but that scientists base explanaitons on proximate and ultimate causes. Using bees as the experimental animals, propose explanations (hypotheses) based on these three perspectives - anthropomorphic, proximate, and ultimate - and then propose a researh project for those hypotheses that can be tested scientifically.

a) Anthromorphic causes:

- possible research project:

b) proximate causes:

- possible research project:

c) ultimate causes:

Could an experiment similar to this be used to investigate ancestors of insects and isopods and to answer questions about when these groups diverged?

Do new beneficial mutation evolve simultaneously andindependently with several individuals of the same specie or onlywith one specimen who then transfers it to all of the specie?

In other words, when we talks about common ancestor we usuallymean a specie, so for example, all earth dwelling reptiles, birdsand mammals are the descendants of Tiktaalik (to the best of myknowledge), and we know that Tiktaalik was the first (or one of thefirst) species to come to land, but was there a first individualTiktaalik who went to the land, like Tim Minchin's Tony thefish.

Imagine being the first dude ever to have feet...

Imagine you're a fish, and you are swimming in the ocean ... andsuddenly out of nowhere Tony just goes "I'm getting out, I'mfreezing, I'm just gonna pop out for a bit, maybe lie on my towel,I'll bring you an ice cream"

-"Don't bother ,Tony, you are a freak! Tony is a freak, let'sgo, let's ostracize him for being different"

It seems to me that from the same species of ancestors there areseveral descending distinct species, so it seems to me that thatthat there was a species of reptiles that at some point someindividual of that group developed Dinosaur features and traits andwhose descendants became Dinosaurs and then Birds, and anotherindividual of that specie or a descending specie (not necessarilyat the same time) developed mammary glands whose descendants becamemammals, and other individuals who didn't mate with those two whosedescendants remained reptiles.

Was there ever a first dinosaur with feathers who is the fatheror mother of all birds, or the first fish with lungs, the firstmonkey with opposable thumbs from whom all apes descend, or thefirst mammal that decided to go for a swim and all dolphins, whaleand seals are his direct descendant of that first swimmingmammal?

And also for traits that don't lead to speciation, was there afirst human who was lactose tolerant, and all the lactose tolerantpeople on the world are his/her descendants, or the first personwith no wisdom teeth, the first person with slanted eyes, and thefirst person with red/blond hair?

*- If there are gross inaccuracies and/or over-simplification inmy understanding of the evolutionary process, this is because I'mnot a biologist, and I would accept happily any correction.

The following is from a Mosquito Dunks® label. Mosquito Dunks® are used to control mosquito larvae populations in standing water.

ACTIVE INGREDIENT:

Bacillus thuringiensis var israelensis, Serotype H-14 primary powder,

7000 Aedes aegypti international toxic units (ITU) per milligram (dry weight basis)… 10%

INERT INGREDIENTS…………………………………………………………………….. 90%

A. The active ingredient in Bti products is a crystalline protein protoxin produced by Bacillus thuringiensis subspecies israelensis ______. (endospores or bacteria)

B. Describe, in some detail, how these protein crystals kill insect larvae.

C. Bt bioinsecticides are toxic to insect larvae that eat them, but are not toxic to humans and other animals because.....PICK ONE--humans eat very little of the product, while insect larvae at a lot of it; humans are much larger than insects and are less likely to be affected; Actually, Bt insecticides are toxic when eaten by humans and other animals; the B. thuringiensis protoxin is activated only in the basic environment of the insect gut

D. Nolo Bait®, which contains spores of the obligate intracellular fungus Nosema locustae, has been licensed by the EPA as a control measure for grasshoppers. Nolo Bait is also called “Grasshopper Spore.” N. locustae spores and bacterial spores are similar in all of the following ways EXCEPT: Both spores remain inert under adverse conditions; Both spores can remain viable in the environment for long periods of time; Both spores are used for reproduction; All of the above are true of both types of spores

E. What unusual cellular characteristic does N. locustae share with the protist Mixotricha paradoxa, the organism discussed in the article “A Russian Doll of Symbiosis?”

F. Photorhabdus luminescens is perhaps the most unusual microbe yet proposed to be used as a bioinsecticide. Photorhabdus luminescens and the microscopic worm Heterohabditis bacteriophora are (bacteria, symbionts, nematode worms, wax worms) The P. luminescens (nematode worms, wax worms, bacterium) lives in a (nematode worm, wax worm, bacteria) host. This host then parasitizes an insect larva, and the (wax worm, nematode worm, bacteria) within it produce (toxins, bacteria, spores) that kill the (nematode worm, wax worm, bacteria).

G. The relationship exhibited by P. luminescens bacteria and the nematode worm Heterorhabditis bacteriophora is a good example of ________. (commensalism, parasitism, or mutalism)
