The cancer has not invaded other tissues is the conclusion which can be made if the cell margins of a biopsy are clear when observed under a microscope in this scenario.
<h3>
What is Biopsy?</h3>
This medical procedure involves taking sample of cells or tissues from parts of the body and observing it under a microscope.
The microscope function is to enlarge the objects which are positioned on the objective lens thereby making it possible for them to be seen more clearly and accurately.
If the cell margins of a biopsy are clear when observed under a microscope, it means the cancer hasn't invaded other parts while in a scenario where the cell margins are crowded then it depicts the presence of cancerous cells thereby making it the most appropriate choice.

A biologist would most likely concentrate on homologous features to find and analyse an evolutionary relationship between two species, finding homologous traits between species might help biologists to understand the evolution of animals, whereas concentrating on analogous features might help to compare the evolution of different species. Hope this helped!
The main aspect used to differ coniferous tree are their leaves. Coniferous leaves look like elongated needles, instead of the regular flatend out leaves we're used to
Further characteristics:
Seeds are hard and grow in large groups, stuck to eachother.
Coniferous are evergreen trees (don't shed leaves nor change the colour of these, although this rule does not apply to all of them).
They have spread worldwide.
Can withstand low temperaurees and can be found even in places like the Artic circle.
I've pasted some images down below that might help you a lot. (Left - leaves; Right - coniferous trees).
Hope it helped,
Happy homework/ study/ exam!

Answer: The reason why stem cell research is a big field in biology or even the world is because stem cells might be able to treat degenerative conditions as well as answering questions about human development.
