Some snakes have special sensory organs that detect the infrared region of the electromagnetic spectrum. Compared with human vision, these snakes can sense electromagnetic waves that have: a lower frequency and a shorter wavelength.
a higher frequency and a longer wavelength.
a lower frequency and a longer wavelength.
a higher frequency and a shorter wavelength.

The correct answer is - a lower frequency and a longer wavelength.

Explanation:

According to the question and generally, some snakes have special organs that can sense or detect the Infrared region of the electromagnetic spectrum. However, human eys can not see or detect the infrared region.

Infrared waves have a longer wavelength and lower frequency in comparison of visible light, visible light can be seen by human eyes.

Thus, the correct answer is - a lower frequency and a longer wavelength.

answer; i believe the answer is (polygenic inheritance;

i think its the first one
