Answer:
a. lethargy, weight gain, cold extremities, and constipation
Explanation:
Caused by a decrease in thyroid hormone T3 (triiodothyronine) and T4 (thyroxine) production, hypothyroidism can lead to fatigue (lethargy), weight gain, cold intolerance, constipation, skin dryness, thinning hair, increased rates. cholesterol and menstrual flow, plus infertility and depression. These symptoms are not always all present, which makes it necessary to research thyroid dysfunction in front of any of them.
Although the reason has not yet been discovered, diseases caused by thyroid malfunction are more common in females. In addition, the risks increase with age. Thus, endocrinologists advise women over 40 in particular to have their thyroid self-examination periodically.
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. It was an important step in the movement away from spontaneous generation.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
The first of these tenets is disputed, as non-cellular entities such as viruses are sometimes considered life-forms.
