"Identical twins are more similar on the trait than fraternal twins" would lead to the conclusion that genetic factors are important in the development of this trait.
<u>Option: C</u>
<u>Explanation:</u>
Research performed on identical or fraternal twins are twin investigations. We seek to expose the significance for characteristics, phenotypes and diseases of environmental and genetic factors. Twin work is considered a key instrument in the domains of behavioral genetics and material, from biology to psychology.
Fraternal or dizygous twins each share around 50 % of their DNA, just like any other parent. Since the twins are born into the same family they share other factors of their surroundings. The existence of a given genetic or phenotypic trait in just one component of a pair of twins called discordance offers a valuable insight into influence on such a trait on climate.
Answer:
Due to the large number of fossils being discovered at that time Darwin proposed that species change over long periods of time.
Explanation:
The theory of Darwin was that the species change in accordance to their environment, thus they develop advantageous traits so that they can be more competitive.
Answer:
the kidneys excrete salt into the urine when dietary salt levels rise
Explanation:
Hyponatremia is an electrolyte imbalance, with a low level of sodium in the blood. The normal value of sodium in adults is 136 to 145 mEq / L. Sodium is an element, or electrolyte of the blood. Sodium chloride is commonly known as table salt.
Certain conditions can cause decreased sodium in the blood. Specific causes of hyponatremia include:
Water poisoning (water replacement without electrolyte replacement).
Problems in the kidneys, heart or liver.
Medications: such as diuretics, Heparin, certain chemotherapeutics (Aminoglutethimide, Cyclophosphamide and Vincristine).
Conditions related to steroids, hormones or metabolic defects, such as a syndrome that alters the secretion of antidiuretic hormone (SSIHA). If this occurs, you urinate frequently and the kidneys excrete too much sodium. This can result from many conditions, including certain types of lung cancer.
