Using powerful new sequencing technologies, investigators can now catalog every rna molecule made by a cell and determine at what quantities these rnas are present. in an experiment, researchers measured the relative quantities of two different mrnas—one transcribed from gene a, the other from gene b—in two different cell types. gene b is expressed in both the liver and the brain whereas gene a is expressed in the brain but not in the liver. which most likely encodes a housekeeping protein?

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
