What is the easiest way to remove earwax inside the ear canal?
astra-53 [7]
The easiest way to remove earwax inside the ear canal is to just use a washcloth. You also can try putting a few drops of baby oil, hydrogen peroxide, mineral oil, or glycerin in your ear to soften the wax. Or you can use an over-the-counter wax removal kit. Besides cotton swabs or any other small or pointy objects, don't use ear candles to clean your ears.

Compare the distribution of ion channels along unmyelinated versus myelinated axons and explain how this accounts for the differ
zloy xaker [14]

Answer:

Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker

Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon

Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.

N/B; Harder to generate action potential in demyelinating disease

axon diameter( bigger diameter= less resistance= faster current).

Research 2 cost effective health insurance plans
noname [10]

Explanation:

lthough studies have examined both the adverse consequences of lacking health insurance and the costs of insuring the uninsured, there are no estimates of the value of providing health insurance to those currently uninsured. To examine the value associated with providing insurance to those currently uninsured through an incremental cost-effectiveness analysis. People aged 25 to 64 in both the National Health Interview Survey (with 2-year mortality follow-up) and the Medical Expenditure Panel Survey were examined to estimate the contribution of sociodemographic, health, and health behavior characteristics on insured persons' quality-adjusted life years (QALYs) and healthcare costs. Parameter estimates from these regression models were used to predict QALYs and costs associated with insuring the uninsured, given their characteristics for 1996. Markov decision-analysis modeling was then employed to calculate incremental cost-effectiveness ratios. The incremental cost-effectiveness of insurance for the average 25-year-old adult (through age 64) is approximately $35,000 per QALY gained (range $21,000 to $48,000). The incremental cost-effectiveness ratio becomes more favorable as people approach age 65. The additional health care purchased with health insurance provides gains in quality-adjusted life at costs that compare favorably to those of other programs and medical interventions society now chooses to fun
