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?

choose one:

a. both genes
b. neither gene
c. gene b only
d. gene a only

If two parents who's blood types are both b produce a child that has blood type o, what can you say about the parent's genotybes? oa) one is ii ob) one is ibi oc) both are bi od) nothing, this is impossible

Need the diagram below, which is not drawn to scale, shows the position of the earth, moon, and sun. what type of eclipse occurs when the earth, moon, and sun are lined up in the order shown? a. planetary eclipse b. solar eclipse c. martian eclipse d. lunar eclipse

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
