The correct answer is Manganese (Mn).
<span>Manganese functions as a cofactor for a large variety of enzymes with many functions including those active in gluconeogenesis. <span>Pyruvate carboxylase that catalyzes breakdown of pyruvate to oxaloacetate requires manganese (or magnesium) for its function. Phosphoenolpyruvate carboxykinase also needs Mn.</span></span>
Answer: Polygenic means that most traits are controlled by an additive effect of two or more genes on a single phenotype.
Explanation: Polygenic inheritance or quantitative characters are those that vary in the population along a continuum. For example, height, skin color, etc.
Often, penetrance, pleiotropy, epistasis, expressivity and environmental factors are involved in producing a continuous distribution of phenotypes.
Traits such as height that show a continuous range of variation and do not behave in a single Mendelian fashion are known as quantitative or complex traits.
Answer: a. Identical twins who grew up together are essential for these studies so that we can see if environment is really an influence or not. Maybe it could be a different case for each one of them. So by comparing them we can know.
b. The results of inherited variation would be that the offsprings would get the same type of characteristics from their parents while environmental variation is variation causedby the environment like heat, temperature, etc.
Explanation:
Answer:
Icecaps, Glaciers and Groundwater
The study of comparative anatomy predates the modern study of evolution. Early evolutionary scientists like Buffon and Lamarck<span> used comparative anatomy to determine relationships between species. Organisms with similar structures, they argued, must have acquired these traits from a common ancestor. Today, comparative anatomy can serve as the first line of reasoning in determining the relatedness of species. However, there are many hidden dangers that make it necessary to support evidence from comparative anatomy with evidence from other fields of study.</span>
