What is the principle for dating materials using radioactive isotopes
nevsk [136]

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

<h3>How are isotopes used in radioactive dating?</h3>

These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

List tim''s symptoms and identify the organ system (or specific organ) associated with those symptoms. (your may need to referen
pantera1 [17]
1. Tim's symptoms include deteriorated coordination, stamina and school performance, nausea, painful joints and an abnormal increase in growth rate. His personality also changed which manifested as depressive mood, introversion, anxiety and tension. These symptoms could indicate an endocrinological problem, therefore the organ system which could be associated with them is the thyroid gland.

2. The thyroid gland is an organ of the endocrine system which is located in the neck, behind Adam's apple. It regulates metabolism, protein synthesis and development. It does so by producing a number of hormones: calcitonin, thyroxine and triiodothyronine. The two thyroid hormones (thyroxine and triiodothyronine) regulate the body's metabolism by controlling the way cells produce and consume energy.

3. Hyperthyroidism is an endocrine condition in which there is an overproduction of thyroid hormones by the thyroid gland. Under these conditions, the thyroid gland proves to be overactive and the main symptom is the acceleration of the metabolism. Tim's sudden increase of growth rate and inability to gain weight, along with his nervousness and mood swings, and his fatigue and loss of energy could indicate a problem of hyperthyroidism.

4. Cortisol is a steroid hormone which is produced by the thyroid gland. It is often called as the "stress hormone" as it is released in response to a stressful situation. It is also released in response to low blood glucose concentration. Some of cortisol's functions are the increase in blood sugar, the suppression of the immune system and bone formation. Cortisol is also involved in the metabolism of macronutrients.

Why were slaves important to the colonial economy? Hint: discuss economic interdependence found in the lesson Answer:
bekas [8.4K]

There are many reasons to why slaves were essential in the colonial economy:

Slaves were generally used more in the south, because large plantations were found there, which meant that the need for large amounts of workers.

Slaves provided cheap labors, and as they were not "citizens" of the US, they were not allowed their rights.

Slaves were also relatively easy to buy and replace, however, their survival rates were not that good after they traveled long distance.

etc.

hope this helps
