To find out which ingredient the cockroaches are refusing, you can carry out a controlled experiment. hydramethylnon is dissolve

d in oleic acid before being mixed with corn syrup to prepare the poisoned bait, so you should test all three ingredients. suppose you conducted a feeding trial to test each ingredient. in the trial, a set of four agar dishes, three containing all except one ingredient and one with all three ingredients (the control), were weighed and placed 3 cm apart on the kitchen floor in an infested apartment. after two days, the dishes were weighed again to measure food consumption. you then repeated the trial 4 times and averaged the results

Answer:

The correct options for this question are:

<span>A) Roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish.
B) Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.
F) Roaches are refusing corn syrup.</span>

<span>
</span>

<span>In this scenario (before pesticides were ever introduced to cockroaches) a certain subset of the population was genetically more likely to avoid oleic acid for whatever reason.  Traits like this float throughout populations and contribute to genetic variance.  When pesticides are introduced to the population, cockroaches with the previously neutral trait of oleic acid avoidance were now given a significant boost in regards to their relative fitness.</span>

1. Do these results support the claim that application of the jewelweed is a good treatment for symptoms caused by poison ivy? E
-Dominant- [34]

A claim is an unverified statement or theory which is made about something which may or may not be true.

<h3>Verification of a claim</h3>

For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.

With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.

If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.

Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.

Why is it important to study grouse habitat selection and demography relative to human land use practices?
nadya68 [22]
Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.
