Answer:
The correct option is B
Explanation:
The alpha and beta-gamma subunits both can bind to target proteins. Once a G protein becomes active, its alpha subunit and beta-gamma dimer both have the ability to pass on messages in the cell via connecting or binding with other membrane proteins that are involved in the transduction of signals. In this light, B is the best option.
Clearly, an IV solution of D5W (5% dextrose in water) is a clear solution, not light yellow. The nurse should check the patient's chart if the IV fluid ordered is really D5W. If it is confirmed that D5W is the IV fluid of the patient, then the nurse should replace the IV bag with a new one with clear contents and make an entry in the chart about what was observed and why the previous bag was replaced.

Answer:
True
Explanation:
Hello!
In the human body, meiosis is the process by which specialized cells divide to form gametes (ovum in women and sperm in men).
Through the meiosis process, four haploid cells are obtained from a diploid cell. Haploid cells are those that have only one set of chromosomes.
In women, only one of the four haploid cells formed keeps all the organelles of the stem cell acquiring a large size (ovum).
In fertilization, a haploid sperm fertilizes a haploid egg giving rise to the zygote (diploid) that will give rise to a new aoganism.
When meiosis is not completed correctly the gamete may contain a duplicate (2 copies) of one or more chromosomes, in this case fertilization normally occurs but may give rise to:
-An unviable zygote.
-A viable zygote with a genetic disease due to a trisomy of one of its chromosomes (Dawn syndrome is an example with the trisomy of chromosome XXI).
