put together a T- chart of three unscientific ideas and misconceptions about diseases and provide scientific explanations in order to clear these misconceptions.​

Answers

Answer:

The three ideas not based on scientific evidence are:

Pregnancy causes your teeth to lose scale.

Lower fever with hot baths.

Brush your teeth with pure baking soda to avoid cavities.

Explanation:

During pregnancy, bone decalcifications occur if the mother has the beginning of malnutrition or advanced malnutrition, said this, decalcification occurs in long bones or other parts of the body since they are the sources with the highest calcium, calcium is never taken from the dental hydroxyapatite structure since this is hexagonal, more difficult to reabsorb and also the calcium concentration is lower compared to a tibia or other long bone. The loss of teeth occurs due to lack of hygiene and periodontitis associated with infectious factors due to the presence of bacterial plaque enhanced by the hormonal degree.

The following explanation is what I name in terms of fever, since it is lowered by immersing the person in warm water, where it cools slowly so that the external cold temperature takes the body heat and reduces the excess temperature generated by the hypothalamus, it is never good to bathe with hot water since in this way we increase the internal body temperature more because our body does not give heat to the environment, but takes more of it.

The ideal would also be to take an antipyretic such as paracetamol since it influences at the level of the CNS and works in the hypothalamus that is why it is a good antipyretic.

Finally, sodium bicarbonate is an abrasive, which wears down the adamantine surface of the teeth, generating micro-abrasions that then facilitate the retention of dental biofilm, causing it to decalcify the hydroxaxyapatite and form caries by acting as a micro-abrasion site. retention, then SALTS LIKE BICARBONATE SHOULD NOT BE USED TO ELIMINATE CARIES OR CURE THEM, for this it is necessary to go to the alodontologist and take a good habit of dental hygiene in a correct and personalized way.

1.Which detail supports the conclusion that some people are hopeful about the new
coronavirus vaccines? *
A vaccine teaches the body to produce antibodies, which are proteins that attack and
disable germs. If the same real germs enter the body in the future, antibodies are
ready to fight them off.
These instructions influence how an organism looks and behaves. Knowing the DNA
of the virus has helped researchers better understand the virus and how to protect
against it
In order to develop a vaccine that is safe for human use, you need to have a clinical
trial. This is a research study in which human volunteers are assigned to a treatment
plan and are then evaluated to see its effects.
The results suggest that a vaccine to protect people against the virus might be close.
Some experts predict a vaccine could be ready by the end of December 2020.

Answers

Answer:

A vaccine teaches the bodies to produce antibodies, which are proteins that attack and disable germs... etc.

Explanation:

Vaccines are basically injections of dead viral infections so our body can prepare to fight them off. Our body doesn't register that they're dead viruses, so we may or may not feel well while the antibodies fight the virus. Sometimes that's why we contract the flu after getting a flu shot. Our bodies believe it is the flu virus, so it prepares to act accordingly. every symptom or side effect of an illness is how our bodies react to it, and how our bodies have decided to fight against it.

Becky is 16 years old and wants to find her Target Heart Rate for vigorous-intensity physical activity. She finds her MHR to be 204. Next she multiplies her MHR by 77% and 93%. Becky’s THR would be

Answers

Answer:

Becky’s THR would be between 157 bpm and 190 bpm during the physical activity.

Explanation:

From the given information;

Since Becky is 16 years old, in order to evaluate the MHR, we deduct the age from 220.

Therefore, the evaluation of the maximum age-related heart rate MHR = 220 - 16 = 204 beats per minute

We are being told that she then multiplies her MHR by 77% and 93%.

i.e

77% level: 204 × 0.77 = 157 bpm

93% level : 204 × 0.93 = 190 bpm

The evaluation indicates that the vigorous-intensity physical activity of Becky at 16 years old will need the target heart rate to remain between 157 bpm and 190 bpm during the physical activity.

what neurosurgical procedures might be tried to improve her hypokinetic parkinsonian movements? Why are these procedures expected to benefit hypokinesia

Answers

Cardinal motor features of Parkinson's disease (PD) include bradykinesia, rest tremor, and rigidity, which appear in the early stages of the disease and largely depend on dopaminergic nigrostriatal denervation. Intermediate and advanced PD stages are characterized by motor fluctuations and dyskinesia, which depend on complex mechanisms secondary to severe nigrostriatal loss and to the problems related to oral levodopa absorption, and motor and nonmotor symptoms and signs that are secondary to marked dopaminergic loss and multisystem neurodegeneration with damage to nondopaminergic pathways. Nondopaminergic dysfunction results in motor problems, including posture, balance and gait disturbances, and fatigue, and nonmotor problems, encompassing depression, apathy, cognitive impairment, sleep disturbances, pain, and autonomic dysfunction. There are a number of symptomatic drugs for PD motor signs, but the pharmacological resources for nonmotor signs and symptoms are limited, and rehabilitation may contribute to their treatment. The present review will focus on classical notions and recent insights into the neuropathology, neuropharmacology, and neurophysiology of motor dysfunction of PD.

Explanation:

domestic violence affects the relation in a family

poverty is an environmental factor since the impoverished have poor hygienic conditions and are sometimes dependent on those around them.

substance abuse is the wrong use of substances like alcohol which is clearly a personal factor.

actually they're all interlinked.

for instance,

poverty affects the whole family which can cause a family member to be violent, he/she takes out the stress through violence, this causes the victim to start substance abuse.

poverty ↦ domestic violence ↦ substance abuse
