As many as 25 percent of the cowboys who participated in the Texas cattle drives were AFRICAN AMERICANS.
Cattle drive was a main economic activity in the Western part of America during the 19th century. The west were known for cattle breeding and they usually have to move these cattle from the home ranches to the rail-heads where they will be bought. The distance between these two points is always great and it may takes as much as two to three months before the distances are covered.

Answer:
The missing answer choices are:
a. hypotonic
b. isotonic
c. osmosis
d. hypertonic
The correct option is <u>d. hypertonic</u>
Explanation:
A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.
