Horizontal gene transfer permits gene flow from one organism's genome to another organism's genome, It occurs commonly between prokaryotes of different species, and even between prokaryotes and eukaryotes.
Phylogenetic Constraint is like a basic body plan. It can be modified (what evolution does) but it can't be fully changed. Vestigial features (things like the human appendix which is a remnant of our ancestors, but is no longer used) provide evidence of common ancestry and phylogenetic constraint. :)
It is difficult to determine the exact drug that is used most frequently, as drug use patterns vary across different populations and regions. However, globally, marijuana (cannabis) is one of the most commonly used drugs. Other frequently used drugs include alcohol, tobacco, and prescription medications.
The most frequently broken bone during birth is the clavicle, also known as the collarbone. This bone can sometimes fracture due to the pressure exerted during delivery, especially if the baby is in a difficult position. However, clavicle fractures typically heal well and do not usually cause long-term problems for the baby.
Brain cells, also known as neurons, do not divide as frequently as other cells in the body because they are specialized and have limited regenerative capacity. Neurons are essential for transmitting information in the brain, and their complex structure makes it difficult for them to divide and replicate like other cells. Additionally, excessive cell division in the brain can disrupt the delicate balance of neural connections and impair brain function.
There are several conditions that can make life difficult, including financial hardship, physical or mental health challenges, lack of social support or relationships, discrimination, and environmental factors such as natural disasters or political instability. These conditions can impact an individual's well-being, sense of security, and ability to thrive in various aspects of life.
Perfect phylogenetic classification is difficult to achieve due to horizontal gene transfer, where genes can be transferred between different species, blurring their evolutionary relationships. Additionally, convergent evolution can lead to similar traits evolving independently in different lineages, making it hard to accurately infer relationships based on traits alone. Lastly, the vast amount of genetic data available now can make it challenging to find a single perfect classification that accommodates all the genetic variations observed.

Thoreau frequently used puns.
true
It is very difficult to say, as the figure frequently changes.
It is difficult to determine the happiest continent as happiness can vary greatly among individuals within each continent. Factors such as economic stability, social support, health care, and personal relationships all play a role in determining happiness levels.
It would be difficult to see any color changes.
Virgo - Gemini relationships tend to be difficult.
Generally speaking a Scorpio - Taurus relationships are difficult.
It's not so much the organism or a type of organism that is difficult to define as a species but rather the differences in the theories regarding the definition of the word 'species'. For example the Biological species concept and phylogenetic species concept can be at odds when looking at convergent/parallel evolution.
