Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
Laboratory tests and clinical procedures include:
- The blood glucose test and the glycosylated hemoglobin test are tests to identify diabetes and prediabetes (A1c).
- A glucose tolerance test may be administered to you if you're expecting to check for gestational diabetes.
- Your thyroid's functionality can be determined by a number of tests, chief among them a TSH measurement.
- Other examinations can evaluate parathyroid problems.
- Female hormonal problems can be identified with the aid of luteinizing hormone (LH) and follicle stimulating hormone (FSH) blood tests.
- Male hormonal problems can be discovered with tests for total testosterone.
- Other blood tests measure hormone levels that have an impact on numerous systems, including cortisol, 17-hydroxyprogesterone, DHEA-sulfate, ACTH, aldosterone, vitamin D, PTH, prolactin, and other estrogen analogues.
- Thyroglobulin (Tg) tests can be used to track thyroid malignancy.
<h3>What is Endocrinology?</h3>
•Endocrinology is the study of endocrine glands.
•Endocrine glands are a group of glands in the body which secrete hormones.
•The purpose of the secreted hormones is to evoke a specific response in other cells of the body which are located far away.
