When doing medical research with human subjects, the following are unavoidable limitations;
It’s often impossible to repeat trials on the same subjects.
Subjects may report an inaccurate medical history.
It can be difficult to control all possible variables
There are ethical or privacy concerns to consider.
Explanation
When doing a medical research that involves human subjects it should be voluntary, informed and consent. The researchers should respect the persons treated as autonomous agents. The volunteers should be protected from physical, mental and emotional harm. The benefits should outweigh the costs.

A Wisconsin fast plant has 2n= 20 chromosomes
Answer:
The answer is D. Nucleus are only found in Eukaryotes.
The microtubules that organize the chromosomes along the metaphase plate are released by centrosomes, also known as microtubule organizing systems. Cytokinesis is the dividing of the cell contents to create two new cells, beginning in anaphase or telophase, and these phases occur in strictly sequential order.
There are 9,0 microtubule multiplets close to the Golgi that generate microtubules. These microtubules utilize dyneins and kinesins to connect to the kinetochores of chromosomes in order to maintain a dynamic movement process and for the centralized organization of chromosomes along the metaphase plate.
Prophase, Metaphase, Anaphase, and Telophase are the four basic phases of mitosis. Some textbooks divide prophase into an early phase (named prophase) and a late phase, giving the number five (called prometaphase).
