Research indicates that as levels of happiness increase, cortisol levels appear to increase as well. Please select the best answ
iogann1982 [59]

Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.

<h3>What are cortisol and its function?</h3>

Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.

It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.

It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.

Therefore, the statement is false.

What occurred during immune system development to result in the presence of antibodies that can bind to the thyroid receptor? g
almond37 [142]

Answer:

If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.

Explanation:

This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.

The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.
