Answer:
Homologous characters
Explanation:
Homologous character is usually defined as those set of characters that are observed in various organisms and are similar to one another. It is because these organisms have obtained these characters from a common ancestor, having that same distinct characters.
The evolution that occurs in this type of organisms are commonly known as the homologous evolution, where the similarities between the organisms are found in terms of physiology, structure and/or other development, depending upon their common ancestors.
Because if we're simultaneously moving/manipulating two different variables it can be very hard to determine why one variable is changing and why the other is changing. While this can be done with more complicated experimental designs, it usually is the case that scientists will only manipulate one variable and not two different ones.
Decomposers are necessary in the food chain because they return nutrients to the ecosystem (2)
<span>Testosterone achieves his effect by binding to his androgen receptor (nuclear). Because testosterone is steroid hormone (derived from cholesterol), it has a possibility to free diffuse through the cell membrane. When testosterone binds, the receptor undergoes a structural change which allows it to move into the cell nucleus and dimerize. Receptor dimer than binds directly to the specific sequence of the DNA called hormone response element (HRE) which results in regulation of gene expression.</span>
