The correct answer is option A
Auxin promotes cell elongation and cell division in stems. They promote stem elongation and inhibits the growth of lateral buds.
This plant hormone is produced in the stem tip and then it travels to the darker side of the plant so that the cells in the darker side grows more than the cells in the lighter side of the plant.

I just took the test and got the answer right :)
Answer:
Spores can travel far.
Explanation:
Spores are carried by the wind or on animal fur.
Bile from the liver is secreted into the small intestine to make the absorption of nutrients more efficient.
B
Involuntary muscles of the small intestine contract to make the absorption of nutrients more efficient.
C
Salivary glands deposit saliva into the small intestine to make the absorption of nutrients more efficient.
D
Villi in the small intestine have thin-walled capillaries to make the absorption of nutrients more efficient.
The correct answer is:
D .Villi in the small intestine have thin-walled capillaries to make the absorption of nutrients more efficient.
Explanation:
The small intestines are well adjusted for absorbing nutrients during digestion by being very long, having villi and microvilli that enlarge surface area, using muscular contractions to move and mix food, and raising and housing digestive enzymes and bile that aid the breakdown of food. The inner surface of the small intestine is not flat but thrown into circular folds, which not only enhance surface area but aid in preparing the ingesta by acting as baffles. Villi: the mucosa makes multitudes of ridges which project into the lumen and are satisfied with epithelial cells.
b. Scientists use relative dating to determine the absolute age of a new fossil.
c. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
d. Scientists use index fossils to determine the specific years of age of a new fossil.

was it the revolution
Outdoor air pollution became a significant problem around the time of the Industrial Revolution due to the increase in industries and coal usage. Heavy industrial cities like London witnessed severe air pollution. However, smaller-scale air pollution has existed since prehistoric times.
Yes, you are correct in assuming that outdoor air pollution became a significant issue around the time of the Industrial Revolution. Beginning in the late 1700s, with the advent of new technology and the increased use of coal as a fuel source, industries began to emit larger amounts of smoke and soot, significantly degrading air quality. Cities fluid in manufacturing, like London, experienced severe air pollution issues, sometimes leading to events such as the 'Great Smog' of 1952. However, it is important to note that forms of air pollution have existed for centuries before the Industrial Revolution, such as dust and smoke from burning wood during the prehistoric era.
