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.
Each human cell contains 46 chromosomes.
Answer:
a nucleus or organelles :)
Explanation:
a prokaryote is a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
Answer:
b. the neritic zone
Explanation:
Neritic zone, also known as sublittoral zone, is a transition zone between the continental domain and the marine domain. It is the area that is under the influence of the tides and where light can penetrate to the bottom, promoting photosynthesis.
This zone is a complex, dynamic, changeable range and subject to various geological processes. The mechanical action of waves, currents and tides are important modeling factors of coastal zones, the results of which are erosion or deposition.
Interferons
Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses.
<h3>What are Interferons ?</h3>
Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
- They also act as signalling molecules that allow infected cells to warn nearby cells of a viral presence – this signal makes neighbouring cells increase the numbers of MHC class I molecules upon their surfaces
- So that T cells surveying the area can identify and eliminate the viral infection.
