Explanation:
The barries of innate immunity are:
Skin: At Epidermal surface, its protective aspect are keratinized cells that lives on the surface, known as Langerhans cells.

Mucosal surfaces: they are at the mucosal epithelium, and their protect aspects are nonkeratinized epithelial cells.
Oral cavity: They defend salivary glands through Lysozyme

Explanation:
Cannibalism is a very essential factor regulating population dynamics of four beetle. After some days of feeding, the flour becomes conditioned by the beetles which can affect rate of cannibalism
Adults have a relatively lower rate of cannibalism. While its highest rate of cannibalism is at larvae stage

Explanation:
This process is called as imprinting. It occurs at a particular stage of life and is, therefore, a phase-sensitive learning process. It can be of many types, including filial imprinting, where an offspring gains some of its behavioral characteristics from the parent, or sexual imprinting, through which desirable characteristics of a mate are recognized by a young animal.
