Which ranks the terms in order of increasing size and the number of space objects contained within? a) size: universe -> galaxy -> solar system number of objects: universe -> galaxy -> solar system b) size: solar system -> galaxy -> universe number of objects: universe -> galaxy -> solar system c) size: universe-> galaxy -> solar system number of objects: solar system-> galaxy -> universe d) size: solar system -> galaxy -> universe number of objects: solar system -> galaxy -> universe

Answer;

A) Size: universe -> galaxy -> solar system  

Number of objects: universe ->galaxy -> solar system

Explanation;The relative size and relationship between the solar system, galaxy and universe is such that; universe is the largest, followed by the galaxy and solar system the smallest.Similarly in terms of the number of objects, objects in the universe are more compared to those of the galaxy and the solar system.In a nut shell, universe refers to everything that exists, galaxies are giant structures that are made up of billion of stars. The universe is made up of billions of galaxies. A solar system is a region of space where the gravitational force of a star influences all the other objects.

E.Inject only the growth factor binding domain of the transmembrane receptor into the cell.

Explanation:

The reception of signals at the level of target cells requires binding of the signaling molecules to the receptors present on the surface of target cells. Some target cells have intracellular receptors for signaling molecules. Reception of signal is followed by signal transduction and production of response.

Mutation in the gene that encodes the transmembrane receptor for the growth factor would not allow the reception and production of response. Therefore, insertion of a growth factor binding domain of the receptor in the mutated cell would allow the cell to exhibit the normal Ras signal transduction pathway.
