Which of the below is a behavioral adaptation in camels? a: large hump to store food and water for long periods of time. b: long eyelashes to block sand from entering the eyes. c: nostrils that can open and close to block debris from entering them. d: spiting when excited or upset.

D. Spiting when exited or upset.

A, B, and C are all physical traits that have nothing to do with emotions.

The correct answer is Option D

Camels have been known to display a set of social behavior. They spit cud when they are excited or injured. Camels also spit as a means of establishing hierarchy, when they are feeding. This is done to so that the lower ranking members of the herd of camels understand that place. Their spit has very powerful odor.

They have adapted these kinds of behavioral adaptations to survive in a better way.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
