7) Describe how the organ of Corti transduces sound waves into electrical potentials.
7a) Describe the neural pathways by which auditory signals for audition reach the cortex.
8) Explain how the brain codes for the spatial location of sound.
Answers
1) The experimental ablation method is a way of demonstrating the function of a particular brain region by removing it or inactivating it temporarily or permanently.
2) The sham-lesion procedure involves a similar surgical procedure to that of an ablation but without damaging the target area.
2a) Inactivation of a brain region involves the use of a drug or some other agent to temporarily disable or block activity within a particular region of the brain.
4) Rod cells are the primary photoreceptors for low-light conditions and are found in the outermost layer of the retina
4a) The generation of action potentials in the retina begins when a photon of light strikes a photoreceptor cell.
6) The dorsal stream is responsible for processing the object's location and motion.
6a) Sound is a physical phenomenon that is produced by the vibration of an object.
7) The organ of Corti is the sensory organ in the inner ear that is responsible for transducing sound waves into electrical potentials.
7a) The neural pathways by which auditory signals for audition reach the cortex begin in the cochlea.
8) The brain codes for the spatial location of sound by using several cues, including interaural time differences, interaural level differences, and spectral cues.
1) The rationale for this technique is that by making an animal brain-damaged in some particular region, researchers can learn more about how that region is involved in behavior. The major advantage of experimental ablation is that researchers can gain insights into what a particular brain region does by examining how a damaged brain differs from a normal one.
2) The purpose of this procedure is to create a control group with identical surgery minus the removal or inactivation of the target region. This allows researchers to control for any nonspecific effects of the surgical process.
2a) For instance, the drug muscimol, which is a GABA agonist, can be used to temporarily inactivate a specific brain area by binding to GABA receptors in that area.
4)Cone cells are photoreceptors that are responsible for color vision, visual acuity, and are found in the center of the retina. Rods are more sensitive to light than cones, and they provide better vision in dim light, while cones provide better vision in bright light.
4)The resulting receptor potential then travels from the photoreceptor cell to the bipolar cell, where it is further amplified. The resulting signal is then transmitted to the ganglion cell, which generates an action potential.
6)It sends information from the occipital lobe to the parietal lobe. In contrast, the ventral stream processes object recognition, sending information from the occipital lobe to the temporal lobe.
6a)The sound waves are propagated through a medium such as air, water, or a solid. The psychological properties of sound include pitch, loudness, and timbre.
7)When the basilar membrane vibrates in response to sound waves, the hair cells in the organ of Corti are also set into motion, generating an electrical signal that is transmitted to the brain.
7a) The auditory nerve carries information from the cochlea to the brainstem, where it is processed and sent to the thalamus. From the thalamus, the information is relayed to the auditory cortex in the temporal lobe.
8)The auditory cortex integrates these different cues to determine the location of a sound in space.

Answers
Answer:
A. Hard
D. 10 days to 8 weeks
D. 5-7 days
A. 10-15 days
Explanation:
By the end of the 2nd trimester, the baby's skeleton is hard. This means that the bones have developed to a point where they can be seen on an X-ray.
The baby is called an embryo from 10 days to 8 weeks after fertilization. During this time, the embryo is undergoing critical development of its major organs and structures.
The blastula or blastocyst stage occurs from 5-7 days after fertilization. This stage is characterized by the formation of a fluid-filled cavity called the blastocoel, which will eventually become the embryo's digestive system.
The morula stage occurs from 0-4 days after fertilization and is characterized by a solid ball of cells that will eventually develop into the blastula.
The placenta begins to form around 10-15 days after fertilization. This structure serves as a vital connection between the mother and developing embryo/fetus, providing nutrients and oxygen while removing waste products.

Explanation:
which of the following modifications is most likely to alter the rate at which a dna fragment moves through a gel during electrophoresis?
Answers
The modification that is most likely to alter the rate at which a DNA fragment moves through a gel during electrophoresis is increasing the length of the DNA fragment, option C is correct.
During electrophoresis, DNA fragments migrate through a gel matrix based on their size and charge. Longer DNA fragments experience more resistance from the gel matrix and migrate slower than shorter fragments.
Altering the nucleotide sequence without changing the length, is less likely to affect the migration rate significantly as the charge and size of the fragment remain the same. Radioactively labeling specific bases, does not directly affect the fragment's size or charge and is unlikely to impact the migration rate. Leaving the length of the DNA fragment the same, would maintain the original migration rate, assuming other factors remain constant, option C is correct.

Proto-oncogenes need or demand only "one" allele (gene copy or variant) to be altered in order to cause cancer (changes in the deoxyribonucleic acid or DNA). One allele is all that is required for a proto-oncogene to develop into an oncogene that causes cancer. Since only one allele (or gene copy) is required to create an oncogene that induces cellular transformation and resulting in cancer, it is referred to as a "dominant" mutation. This type of mutation causes a "gain" in function since the affected cells can now divide uncontrollably and serve a new purpose.

what will happen to the freshwater fish if you place it in sea water and why?
Answers
If a freshwater fish is placed in sea water, it will most likely die.
This is due to the sea water's much higher salinity than what freshwater fish are used to. Osmotic stress is brought on by this, and it can result in electrolyte imbalance, dehydration, and finally death.
Seawater normally has a salinity of 3.5% to 3.8%, whereas freshwater has a salinity of 0%. Since there is more salt in seawater than freshwater, the freshwater fish's cells osmotically lose water, contracting and changing form.
This process can produce an electrolyte imbalance, which can impair important processes like the fish's capacity to take oxygen from the water, ultimately resulting in death.
Further problems and even death may result from the freshwater fish's inability to expel waste due to the presence of salt in the sea water.

Which ion is a found in a glass of water
Answers
In a glass of water, the most common ion found is the hydroxide ion (OH-) and the hydrogen ion (H+).
These ions are formed when water molecules dissociate through a process called self-ionization or autoionization.
In a glass of water, several ions can be found, originating from the dissociation of water molecules. The main ions present are hydrogen ions (H+) and hydroxide ions (OH-), resulting from the self-ionization of water.
Water molecules can break apart spontaneously into equal concentrations of H+ and OH- ions through a process called autoionization. This occurs when a water molecule donates a proton (H+) to another water molecule, forming H3O+ (hydronium ion) and OH-.
Additionally, other ions might be present in a glass of water depending on its source. For example, tap water can contain various dissolved ions like calcium (Ca2+), magnesium (Mg2+), sodium (Na+), chloride (Cl-), and bicarbonate (HCO3-). These ions come from minerals and other substances present in the water source, such as groundwater or surface water.
It's worth noting that the specific ion composition of water can vary depending on factors like location, treatment processes, and water source. However, the fundamental ions present in water are H+ and OH- resulting from the autoionization of water molecules.

Which of the following statements describes a likely effect of a drug designed that inhibits the cellular response to testosterone?a. insufficient ATP levels in the cytosol
b. activation of receptor tyrosine kinases
c. The transcription of certain genes would decrease.
d. GTPase activity and hydrolysis of GTP to GDP
Answers
The statement (c) "the transcription of certain genes would decrease" describes a likely effect of a drug that inhibits the cellular response to testosterone.
A drug designed to inhibit the cellular response to testosterone will either suppress the synthesis of testosterone or will compete with the androgen receptor.
However, the most likely effect of such a drug would be that the transcription of certain genes would decrease. Transcription is the process by which the genetic information in DNA is used to create an RNA molecule.

mitochondria are bathed in amytal (a complex i inhibitor). what are the impacts of this inhibition? would atp synthase stop working?
Answers
Amytal is a complex I inhibitor that blocks electron transport in the mitochondrial electron transport chain (ETC), which is an essential process for generating ATP.
The ETC is responsible for transferring electrons from electron donors to electron acceptors, ultimately creating an electrochemical gradient that drives the synthesis of ATP by ATP synthase.
When mitochondria are bathed in amytal, complex I is inhibited and electron transport is disrupted. As a result, the proton gradient across the inner mitochondrial membrane is dissipated, which means that ATP synthase can no longer generate ATP effectively. Therefore, ATP synthesis would be significantly reduced, and the rate of ATP production would be impaired.
It is important to note that amytal is a reversible inhibitor of complex I, which means that its effects are temporary and can be reversed once the inhibitor is removed. However, if the inhibition is prolonged, it can lead to a decrease in cellular ATP levels, which can have deleterious effects on cellular metabolism and function.

In the small intestine, ___________ correct impulses stimulate peristaltic movements, while ___________ correct impulses inhibit movements.
Answers
In the small intestine, parasympathetic correct impulses stimulate peristaltic movements, while sympathetic correct impulses inhibit movements.
The small intestine is a long, narrow tube that is part of the digestive system. It is responsible for the majority of nutrient absorption and plays a critical role in the digestion of food. Peristalsis is the process by which food is moved through the digestive tract via a series of contractions and relaxations of the smooth muscle in the intestinal wall. The rate and intensity of peristalsis is controlled by the autonomic nervous system.
The parasympathetic nervous system is responsible for stimulating digestive activity, including peristaltic movements in the small intestine. When food is detected in the small intestine, sensory neurons send signals to the brain, which then sends signals back down the vagus nerve to stimulate the release of acetylcholine.

What key structure of the brain is involved in reward, motivation, and addiction?.
Answers
Answer:
Frontal lobes
Explanation:
The key structure of the brain that is involved in reward, motivation, and addiction is ventral tegmental area. The correct option is D.
The VTA is a part of the midbrain that is important to the reward system in the brain. It has dopamine-producing neurons that send signals to the prefrontal cortex and nucleus accumbens, among other parts of the brain.
Dopamine is released once the VTA is activated, which results in sensations of pleasure, motivation, and reinforcement.
Addiction can result from dysregulation of the reward pathways in the VTA because substances or actions that cause the release of dopamine in the VTA can strongly motivate usage or engagement even in the face of negative effects.
