Answer:
a. Species A survived because of its widespread range including some areas that were not as affected by mass extinction.
Explanation:
The species distribution might confer extinction resistance during massive extinction events. One of the most important reasons for a species -or any other taxonomic group- to survive massive extinction is its wide distribution area.
The broad geographical range of a group -as Species A in the example- enhances the survival chances during mass extinctions. When the event occurs, it severely affects most individuals of a certain area. If the species is restricted to that area, then the species will probably disappear, no matter the number of individuals living there.
But if the species is widely distributed, there are more survival chances. The extinction event will only affect a few regions, but not all of them, meaning that some of the individuals of the species will be able to survive.
Probably as only a few individuals of species A got to survive, they must have suffered the effects of genetic drift after the disaster, causing a reduction in genetic variability.
Take note that the total distance that needs to be traveled is 360 miles. The train is moving at 60mph and 2.5 hours have passed. To get the remaining distance, first you need to solve for the distance traveled already.
Distance is equal to the velocity times the time travelling or:

So considering the given we can get the distance traveled in 2.5 hours.



So far, Ainsley traveled 150 miles. If her town is 360 miles away, you can get the remaining by subtracting the distance already traveled from the total distance.
360 miles - 150 miles = 210 miles.
Now if you want to put that into a single equation you can do that by combining all the equations together.
d = 360 miles - (vt).d = 360 miles - (60mph)(2.5 h)
d = 360 miles - 150 miles
d = 210 miles
Acronyms are abbreviations for words like what does it stand for and its basically used to make words stand out and turn long words shorter like for example. VIP is very important person, MVP is most valuable player, and YOLO is you only live once, things like those are meanings in just a small word.
Epigenetic
is a Modifications to bases, changes in histones, and alterations in chromatin
structure. It Changes in the manner in
which DNA is packaged and may affect gene expression. Can be inherited through
cell division; Reversible and responsive to changes in the environment, Example:
Manner in which mammals equalize the expression of X-linked genes in XX F and
XY M.
