Answer:
Social science, any branch of academic study or science that deals with sociology, psychology, political science, and economics. Most historians, however, consider history as one of the humanities.

Geiger-Muller tube is instruments requires you test three times the background of the work area.
<u>Explanation</u>:
These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds
Answer:
Option (A), (B), (D) and (E).
Explanation:
Wings are present in class Aves that helps the birds to fly. Wings provides the means of locomotion and also allow the sexual selection in case of birds. The wings are the modified forelimb of birds.
The bats wings are ancestral whereas birds have derived wings. Birds and reptiles (turtle) mostly have ancestor with wings. On the basis of wings we cannot construct a phylogeny tree. Hence, wings are not the ideal characteristics for the construction of a phylogenetic tree.
Thus, the correct answer is option (A), (B), (D) and (E).
The duplication of homeotic ( H o x ) genes has been significant in the evolution of animals because it <u>permitted </u><u>the </u><u>evolution </u><u>of novel forms</u>
<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.
