These bones are examples of analogous structures since they belong to genetically not too closely related species, such as humans, dogs, birds, and whales, they have the same function, and have a similar structure, but are more distant related in genetic terms.

knowing the nervous system how is that information used in billing and coding ?
Answers
Answer:
In the context of billing and coding, knowledge of the nervous system is essential for accurately documenting and coding medical procedures and services related to neurology and neurosurgery. Medical coders and billers need to understand the anatomy, physiology, and terminology associated with the nervous system to appropriately code diagnoses, procedures, and services provided to patients.
Understanding the nervous system helps in accurately identifying and coding conditions such as nerve disorders, neuropathies, strokes, brain tumors, spinal cord injuries, and other neurologic conditions. It enables the coder to assign the correct International Classification of Diseases (ICD) diagnosis codes, such as ICD-10-CM, which are used to indicate the patient's condition.
Furthermore, knowledge of the nervous system assists in coding procedures and services related to neurology, such as nerve conduction studies, electromyography (EMG), electroencephalography (EEG), neurosurgical procedures, and interventional neuroradiology procedures.
Accurate coding ensures that healthcare providers are appropriately reimbursed for the services they provide and that the insurance claims are processed correctly. It also helps in data analysis, research, and monitoring trends in neurologic conditions and treatments.
Explanation:
In summary, understanding the nervous system is crucial in the billing and coding process to ensure accurate documentation, appropriate reimbursement, and effective management of neurologic conditions in healthcare settings.

Answers
When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.
Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

If every cell in the body gets the same DNA, how do the cells of an embryo make different structures and take on different roles
Answers
Answer: The options are not given, here are the options.
A. Different transcription factors are active in different cells
B. Different transcription factors are encoded in the DNA.
C. Genes are spliced differently in different cells.
D. Translation is regulated so that different cells may make more of certain proteins.
E. Some cells lack ribosomes while others use them.
F. cells delete a set of unused genes from their chromosomes.
The correct options are;
A. Different transcription factors are active in different cells
C. Genes are spliced differently in different cells.
D. Translation is regulated so that different cells may make more of certain proteins.
Explanation:
Every cell in the body have the same DNA but different function because a single cell in the body divides many times into several cells and these cells have the same DNA , DNA is the genetic information needed to make a person and it is stored in over 20,000 human genes found in almost all the cells in the body.
For the gene to be expressed into information, it must be made into protein and the protein goes out and perform some specific functions.
And for a cell to work, alot of proteins must be made to perform different functions.
Different transcription factors are active in different cells which make cells to perform different roles and functions.
Genes are spliced differently in different cells to make different proteins performing different task.

You have isolated a highly lethal toxin from an octopus that you have reason to believe binds with high affinity to the pore opening of a voltage-gated sodium channel. To determine the effect of toxin binding, you perform a _______ experiment.
Answers
Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

Stratovolcanoes – Mt. Saint Helens, WA. Fly to Mt. Saint Helens in the Cascade Range of western Washington, and then turn on the Mt. Saint Helens Contour Map overlay. The brown lines are contours (lines of equal elevations). Use the Ruler tool to determine the horizontal distance (ft) between the Problem 7 placemarks and then subtract the elevations (ft) for each placemark from the contour map to determine the relief (vertical distance). Find the slope angle of Mt. Saint Helens using the following formula (this value is representative for many composite cone volcanoes): slope angle = tan–1 (relief ÷ horizontal distance) Choose one: 5°–10° 15°–20° 25°–35° 35°–45°
Answers
Scientists have concluded that the magmatic system of Mount St. Helens has evolved from a relatively simple to a more complicated state as the volcano matured based on a thorough chemical examination of the eruptive products from each stage of volcanism.
According to the data, interaction between more mafic (basalt to andesite) and more silicic (dacite) magma batches increased from the earliest to most recent stages of Mount St. Helens volcanism. The volcano's initial eruptive phase mostly comprised of a cluster of domes encircled by an apron of tephra and debris fans of broken volcanic materials. Large portions of a center cluster of dacite domes and surrounding fans were buried by these lava flows, which sparked the cone-building process.
