Answer:
In evolutionary studies, absolute dating can be described as a method which scientists use to date any material that they find. Relative dating is a method in which scientists try to puts the geological events in a relative order. In absolute dating, the exact age of the rock will be calculated by the scientist. In relative studies, the scientist will try to place the rock in the best geologic time in which the rock might have existed.
The most common method for absolute dating is the method of radiometric dating. Radioactive minerals present in the rock act as geologic time which are determined by the scientists.
Answer: hyponatremia
Explanation:
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. ... Severe symptoms include confusion, seizures, and coma.
Answer;
-The bacterium would exhibit positive chemotaxis.
Explanation;
-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.
Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.
