"The Glossopteridales (Glossopteris fossils) occur on the most landmasses. Their distribution across several detached landmasses led scientists to believe that these were once merged into a single supercontinent, Pangea. Their wide distribution suggests that the continents were still together in the times of their existence (298.9 millions of years ago-252.17 millions of years ago). Scientific evidence suggests that Pangea did indeed split after this, 175 million years ago." Credit goes to MaximS who answered the same question on

Answer:
d) the group that is subjected to the change that the independent variable represents.
Explanation:
Experimental group: The experimental group is also referred to as a treatment group because this is the group that receives treatment in a given experiment. Here, the group refers to test subjects like animals, people, plants, etc. In the experimental group, the independent variable is being changed.
In an experimental research study, the group which is an experimental group is the group that is subjected to the change that the independent variable represents.
The brain area pinpointed is known to be intimately involved in some of the most advanced planning and decision-making processes that we think of as being especially human.
'We tend to think that being able to plan into the future, be flexible in our approach and learn from others are things that are particularly impressive about humans. We've identified an area of the brain that appears to be uniquely human and is likely to have something to do with these cognitive powers,' says senior researcher Professor Matthew Rushworth of Oxford University's Department of Experimental Psychology.
MRI imaging of 25 adult volunteers was used to identify key components in the ventrolateral frontal cortex area of the human brain, and how these components were connected up with other brain areas. The results were then compared to equivalent MRI data from 25 macaque monkeys.
This ventrolateral frontal cortex area of the brain is involved in many of the highest aspects of cognition and language, and is only present in humans and other primates. Some parts are implicated in psychiatric conditions like ADHD, drug addiction or compulsive behaviour disorders. Language is affected when other parts are damaged after stroke or neurodegenerative disease. A better understanding of the neural connections and networks involved should help the understanding of changes in the brain that go along with these conditions.
The Oxford University researchers report their findings in the science journal Neuron.
Professor Rushworth explains: 'The brain is a mosaic of interlinked areas. We wanted to look at this very important region of the frontal part of the brain and see how many tiles there are and where they are placed.
'We also looked at the connections of each tile -- how they are wired up to the rest of the brain -- as it is these connections that determine the information that can reach that component part and the influence that part can have on other brain regions.'
From the MRI data, the researchers were able to divide the human ventrolateral frontal cortex into 12 areas that were consistent across all the individuals.

Answer:
Minutemen were civilian colonists who independently formed militia companies self-trained in weaponry, tactics, and military strategies, comprising the American colonial partisan militia during the American Revolutionary War. They were known for being ready at a minute's notice, hence the name.
