They are solitary animals, especially males who do not live in groups, unlike the female which can form small groups of three or four members with their young.
The males are very territorial, so take care of their personal space and the females with whom they mate. To mark their territory, they spray the trees and rocks with a mixture of urine and musk.
Both male and female, they are related only in times of mating and reproduction. There have been cases where the male is responsible for feeding breeding if the mother has died.
The gestation period lasts between 98 and 108 days and give birth to two to four cubs weighing just over a kilo. They have a short life expectancy, as only get to live 10 to 12 years in the wild, but in captivity Natural mortality manage to live up to 26. It is mainly due to the fighting between males
Answer:
The endoderm gives rise to the nervous system.
Explanation:
Gastrulation is the process that occurs during the third week of embryonic development and includes transformation of embryonic disc with epiblast and hypoblast into a three layered embryonic disc made up of ectoderm, mesoderm and endoderm. These are the three primary germ layers and give rise to various tissues and body organs.
Endoderm of the embryo give rise to epithelial lining of gastrointestinal tract (except the buccal cavity), respiratory tracts and other organs such as gallbladder, liver,etc. Mesoderm forms connective tissues such as bones as well as muscles and peritoneum. All the tissues of nervous system and epidermis of skin are derived from ectoderm.

Secondary or second-level consumers eat primary consumers. Tertiary or third-level consumers eat lower-level consumers and are sometimes called final consumers. Some secondary and tertiary consumers eat plants as well as lower level consumers, making them omnivores.
