Introduction :
Behaviour is the way an animal reacts to a stimulus. The stimulus is an external alteration that directly affects the behavior of the organism. Animal habits are innate and acquired habits that have evolved through natural selection. Learned habits are the product of associations between natural behavior and previous experiences in a specific environment.
Answer to Problem 5STP
Correct answer :
The correct answer is option (B) A female chimpanzee takes care of her infant for three years.
Explanation of Solution
Explanation/justification for the correct answer :
Option (B) A female chimpanzee takes care of her infant for three years. When parents provide care to their offspring in the early stages of development, they are engaging in nurturing behaviors. For example, a female chimpanzee will give birth to one baby which she will nurse for up to three years. So, this is the correct option.
Explanation for incorrect answer :
Option (A) An animal in a colony spots a predator and warns the whole colony. Auditory communication enables animals to send and receive sound signals that travel faster than chemical messages. So, this is an incorrect option.
Option (C) A male peacock displays its feathers in front of a female. An animal engages in court actions to attract a companion. Courtship signs like a show of brightly colored feathers or a sequence of gestures or sounds are species-specific. So, this is an incorrect answer.
Option (D) A squirrel chatters at another squirrel to drive it away. Chattering squirrels is a territorial behavior. Territorial activity is an effort to claim and regulate a physical area against other animals of the same species. So, this is an incorrect answer.

Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forward

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forward
