Based on the results of the feeding experiment, what conclusions can you draw? select all that apply. (for help interpreting the results, see the hints.) roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish. roaches ate about the same amount from the dish with no oleic acid as they did from the control dish. roaches ate about the same amount from the dish with no corn syrup as they did from the control dish. roaches are refusing hydramethylnon. roaches are refusing oleic acid. roaches are refusing corn syrup.
Answer:
1. The roaches ate about the same amount from the dish without hydramethlynon as they did from the control dish.
2. Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.
6. Roaches are refusing corn syrup.
Explanation: The cockroaches ate the most bait when it did not have corn syrup in it, and ate very little of any bait that had corn syrup. Further experiments like this one have shown that it is actually the glucose in the corn syrup that the cockroaches detect and refuse.
Final answer:
Conclusions from the feeding experiment indicate that both hydramethylnon and oleic acid act as repellents to cockroaches if they are refusing to eat from dishes containing these substances, while corn syrup is likely an attractant if they eat less from dishes without it.
Explanation:
Based on the results of the feeding experiment, several conclusions can be drawn about cockroach behavior and preferences. If roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish, it suggests that hydramethylnon is not acting as a deterrent. Similarly, if they ate about the same from the dish with no oleic acid as from the control dish, this indicates that oleic acid is not repelling the roaches. On the other hand, if roaches are refusing to eat from dishes containing hydramethylnon or oleic acid, it shows these substances are effective repellents. Finally, if roaches ate less from the dish without corn syrup compared to the control, it implies that corn syrup is an attractant to cockroaches.
How does the adrenal gland respond to stress? the adrenal cortex secretes mineralocorticoids and glucocorticoids in response to short-term stress. the adrenal medulla secretes epinephrine and norepinephrine in response to long-term stress. the adrenal cortex secretes epinephrine and norepinephrine in response to short-term stress. the adrenal medulla secretes epinephrine and norepinephrine in response to short-term stress. the adrenal medulla secretes mineralocorticoids and glucocorticoids in response to long-term stress?
The adrenal medulla secretes epinephrine and norepinephrine in response to short-term stress. The adrenal cortex responds to long-term stress by secreting glucocorticoids and mineralocorticoids, which affect various metabolic processes and are necessary for the body to adapt to chronic stress conditions.
The question concerns how the adrenal gland responds to stress. In response to short-term stress, the adrenal medulla secretes epinephrine and norepinephrine, which are hormones that mediate the fight-or-flight response. This process is mediated by the sympathetic nervous system (SNS). On the other hand, the adrenal cortex is responsible for responding to long-term stress by secreting glucocorticoids like cortisol and mineralocorticoids like aldosterone after being stimulated by adrenocorticotropic hormone (ACTH) from the anterior pituitary gland, which is triggered by the hypothalamus.
The corticosteroids released by the adrenal cortex play essential roles, from affecting glucose metabolism and stimulating glucose synthesis to the breakdown of fat into fatty acids in the adipose tissue which are then used for ATP production. Such hormones are necessary for the body's adaptation to long-term stress conditions but should not be used excessively in a medicinal capacity due to potential immune-suppressing effects, such as increased susceptibility to disease.

Nearly one billion dollars a year are spent on clearing sediment from streams and lakes in the United States.
Which is the most common source of this sediment?
A. productive farmland that is over-irrigated
B. waste dumped by mining industries into the waterways
C. hilly areas where protective vegetation has been removed
Answer: Option C
Explanation: Hills are the most common source of sediments because they lack vegetation. Plants and trees hold the soil and thus prevent erosion of soil layer with water. The sediments from the hilly areas get carried by rain water or runoff, and add to the water bodies, like lakes and streams.
Waste from mining industries don’t have sediments in their waste, so option B is incorrect.
Option A is incorrect because over-irrigation will not affect the soil layer, as it is firmly held by the roots of the crops.

An 8-ounce glass of low-fat chocolate milk contains 160 kilocalories (kcal) and 8 grams of protein. what percent of the kcal in the milk comes from protein?
Final answer:
Protein provides 4 kilocalories per gram. Multiplying the 8 grams of protein in the milk by 4 kcal/g gives 32 kilocalories from protein. This makes up 20% of the total 160 kilocalories in the milk.
Explanation:
To calculate what percent of the kilocalories in the milk come from protein, we need to know how many kilocalories are provided by the protein. Protein provides 4 kilocalories per gram, so if the milk contains 8 grams of protein, the protein contributes:
8 grams of protein x 4 kcal/g = 32 kilocalories from protein.
Next, we'll find the percentage of the total calories that come from protein:
(32 kilocalories from protein / 160 total kilocalories) x 100 = 20%
Therefore, 20% of the kilocalories in the low-fat chocolate milk come from protein.

The catarrhines, including humans, apes, and Old World monkeys, typically have a dental formula of 2-1-2-3, meaning two incisors, one canine, two premolars, and three molars on each side of their jaws.
Explanation:The typical dental formula of catarrhines, a grouping of primates that includes humans, apes, and Old World monkeys, is 2-1-2-3. This means they usually have two incisors, one canine, two premolars, and three molars on each side of their upper and lower jaws. This formula varies somewhat between species, with the primary variation usually being in the number of premolars. For example, in some species of baboons, one of the more common Old World monkey species, the dental formula can sometimes be 2-1-3-3.

Which description of synapses is not correct? which description of synapses is not correct? second messengers can activate gene activities in the postsynaptic neuron. excitatory synapses cause depolarization. direct signaling involves the activation of g proteins. ionotropic receptors are ion channels that open and influence the polarization of the membrane?
Synapses are specialized junctions between neurons that allow for communication and transmission of signals in the nervous system. The description of synapses that is not correct is "Second messengers can activate gene activities in the postsynaptic neuron."
While three of the given descriptions of synapses are accurate, the statement that second messengers can activate gene activities in the postsynaptic neuron is not correct. Second messengers, such as cyclic AMP or calcium ions, play important roles in intracellular signaling and can modulate various cellular processes.
However, they do not directly activate gene activities. Gene activities in the postsynaptic neuron are regulated through complex processes involving transcription factors, DNA binding, and gene expression. Second messengers primarily participate in modulating intracellular signaling cascades and enzyme activities rather than directly influencing gene activities at the synapse.
While second messengers can play a role in intracellular signaling and modulating various cellular processes, including gene expression, they do not directly activate gene activities in the postsynaptic neuron at the synapse. Gene activities are typically regulated by transcription factors and complex cellular mechanisms, not directly by second messengers at the synapse.
Therefore, the description of synapses that is not correct is "Second messengers can activate gene activities in the postsynaptic neuron."

A client who has been taking diazepam for 3 months for skeletal muscle spasms and lower back pain has stopped taking the medication 2 days ago because it was no longer helping. now the pain has increased. the nurse should assess the client for: (select all that apply.)
Final answer:
After stopping diazepam, a client may experience several withdrawal symptoms. The nurse should assess for insomnia, diaphoresis, tremor, and vomiting, which are among the common withdrawal effects after ceasing benzodiazepine treatment.
Explanation:
The subject in question concerns the potential withdrawal symptoms that a patient might experience after stopping diazepam, a medication from the benzodiazepines family. Diazepam is often prescribed for anxiety, insomnia, seizures, and muscle spasms. Given that it is a CNS depressant, abrupt discontinuation after prolonged use can lead to withdrawal symptoms which the nurse should assess.
Insomnia - A common withdrawal symptom due to the rebound effect after cessation of a medication that has sedative properties.Euphoria - Not typically associated with withdrawal; euphoria might be a side effect when using the drug but not when discontinuing it.Bradycardia - Not commonly reported as a withdrawal symptom from benzodiazepines, typically withdrawal could cause increased heart rate rather than slowing it down.Diaphoresis - Withdrawal can induce excessive sweating as the body reacts to the absence of the medication.Tremor - A common symptom of withdrawal from diazepam as the body's nervous system becomes hyperactive.Vomiting - A notable withdrawal symptom that can occur after stopping diazepam.Therefore, the nurse should assess the client for insomnia, diaphoresis, tremor, and vomiting as these are symptoms commonly associated with withdrawal from diazepam.
