Aldosterone stimulates the protein synthesis of sodium and potassium.
Aldosterone is the primary mineralocorticoid steroid hormone produced by the zona glomerulus of the adrenal cortex in the adrenal gland.
It is required for sodium conservation in the kidneys, salivary glands, sweat glands and colon.
It plays a central role in the homeostasis of blood pressure, plasma sodium (Na+) and potassium (K+) concentrations. It does this primarily by acting on mineralocorticoid receptors in the distal and collecting tubules of the nephron.
It affects the reabsorption of sodium and excretion of potassium (from and into tubular fluid, respectively) by the kidneys, thereby indirectly affecting fluid retention or loss, blood pressure and blood volume.
When deregulated, aldosterone may be pathogenic and contribute to the development and progression of cardiovascular and renal disease.

If a state has no minimum wage law or its minimum wage is lower than the federal law, workers are entitled to the federal wage. If a state's minimum wage is higher than the federal one, workers are entitled to the state-specific wage
Answer:
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Explanation:
This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.
Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.
Answer:
In biology, 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.
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.
Explanation:
In biology, 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.
