Answer 1
Answer:

Answer and Explanation:

RYR1 gene plays a pivotal role in muscle contcations. This gene produces a protein called ryanodine receptor 1. This protein is a protein in the sarcoplasmic reticulum, forming a channel in the reticulum membrane, the ryanodine channel, which controls calcium transport, an important step in controlling muscle contractions (skeletal muscles).  Muscle contractions are triggered by the flow of positively charged ions, including calcium, into muscle cells.  When muscles are at rest, calcium ions are stored in the sarcoplasmic reticulum (cellular structure)  inside each muscle cell. In response to certain signals, the RYR1 channel releases calcium ions from the sarcoplasmic reticulum into the (cytoplasm. The resulting increase in calcium ion concentration stimulates muscle fibers to contract, allowing the body to move.Mutation in the gene results in a defective channel protein and allows the release of high amounts of calcium ion relative to the normal channel.

So, I'm polyse.xual, which means I'm attracted to most, but not all genders. When I explain this to people, they say that I'm hom.ophobic. I'm not though. I still support the other genders, I'm just not attracted to them all. These accusations really make my blood boil. In order to stop people from saying I'm hom.ophobic, should I start to tell people that I'm panse.xual or omnise.xual instead, even though I'm not?

Give samples of hypothermia and hyperthermia with meaning​

Answers

Explanation:

Hyperthermia is an abnormally high body temperature, while hypothermia is when your body is too cold.

Hyperthermia

Occurs when your body absorbs or generates more heat than it can release

The body's heat-regulation system becomes overwhelmed by outside factors

Symptoms include:

High body temperature (103°F or higher)

Hot, red, dry, or damp skin

Fast, strong pulse

Headache

Dizziness

Nausea

Confusion

Losing consciousness (passing out)

Commonly known forms include:

Heat fatigue

Heat syncope (sudden dizziness after prolonged exposure to the heat)

Heat cramps

Heat exhaustion

Heat stroke

Hypothermia

Occurs when the temperature drops below that required to maintain normal metabolism

Exposure to colder-than-normal temperatures can cause hypothermia

For example, if you step into an extremely cold, air-conditioned room immediately after being outside, you risk losing too much body heat in a short period

Alcohol and drug use can also cause hypothermia

D. Treatment must be voluntary and can be based solely on drug abuse.

Answers

The correct answer is A. An individual’s treatment plan must be continually assessed and modified to meet the person’s changing needs.

Explanation:

Rehabilitation programs or drug addiction treatments are designed to help individuals that had experienced drug abuse or addictions. Due to this, these programs do not only address medical aspects such as the process of detoxification but also aspects related to habits, emotions, past experiences, relations, among others that help the individual to change and avoid drugs in the future.

Additionally, treatment should be personalized and patients need to be continually assessed because not all addictions are identical and aspects such as causes are particular to each person; also, it is common patients need support to avoid drug abuse or in case this occurs. According to this, the one that is a principle for drug effective treatment is option A.
