Answer:
<u>Pro:</u>
May hold answers to cure various diseases including Alzheimer's and Parkinson's - these may be answers to various diseases that are not able to cure.
Requires a small number of cells because of the fast replication rate - these are able to produce a high amount of cells in the lab as they are able to replicate faster.
Medical benefits such as regenerating organ tissue and therapeutic cell cloning
<u>cons:</u>
ethical controversy over use of stem cells from lab fertilized human egg - there is an ethical controversy around the use of lab fertilized human egg
unproven treatments often come with high rejection rates - these researches provide uncertain results and not tested and easily affected so the rate of rejection is high
The cost can be prohibited for many patients - these require high cost and can not be in the budget of every patient.
<h3><u>Answer;</u></h3>
aquifers

bleeding. Lack of iron in the body is also a cause because a body is in need of
iron and if it does not exceed the required iron in the body, it may result to
iron deficiency.
The answer is D- it allows the phage DNA to be replicated during bacterial replication
Bacteriophage can use two different cycles: the lysogenic cycle or lytic cycle.
the lysogenic cycle is a method by which a bacteriophage can replicate its DNA using a bacteria cell. In this cycle the DNA is only replicated, not translated into proteins so the bacteria won't be killed.
