The Nagoya University study headed by Takashi Yoshimura revealed that birds start singing in spring when days are longer. Their behavior was linked to a hormone called Thyrotrophin which is triggered during longer days. The process results in the expansion of the male testes in birds, which make them sing.
Based on the contour intervals given, the feature that is most likely seen in these topographical maps is A. Streams.
<h3>What feature is on the topographical map?</h3>
Streams generally flow in over gentle elevations which means that the contour intervals are generally spread out and are 50 m or less.
The contour interval here is 50m which means that the most likely feature would be a stream.

Given parameters:
Each interior angle = 150°
Unknown:
The number of sides of this regular polygon = ?
Solution:
To find the sum of internal angles of a regular polygon, we use the expression below;
(n - 2) x 180 = sum of internal angles of a polygon
n is the number of sides,
Also, the sum of the internal angles of a polygon = number of sides x internal angles;
So;
(n-2) x 180 = 150 x n
Solve for n;
180n - 360 = 150n
180n - 150n = 360
30n = 360
n = 12;
Therefore, the number of sides is 12
