Once inside epithelial cells, fatty acids are reattached to monoglycerides reforming triglycerides; triglycerides are then wrapped with other proteins by the Golgi to form Chylomicrons that enter the lymphatic system.

The alula is a small structure that is found on birds. It is located at the joint between the hand wing and the arm wings of birds and it is the freely moving, first digit of a bird's wing. It is normally used by birds in slow flight. In humans, the structure that is comparable to the alula is the thumb.
Ans.
Biological interactions include different types of interactions between organisms that reside together in a community.
Cattle egrets show interaction with domestic cows and feed on the insects present in them. The cattle egrets get food from the cows, while there is no benefit or harm to the cows. This type of biological relationship is known as commensalism, in which one organism, out of interacting organisms, get benefit, while other organism neither harmed or benefit.
Thus, the term that describes this relationship is 'commensalism.'
The bones of the middle ear relay vibrations received from the ear drum. The ear drum is a thin conical membrane between the internal and external ear that perceives sounds from outside and gives it distinctiveness based on number of vibrations, which if further relayed to the brain through various organs. It is also called the tympanic membrane or myringia.
Answer:
The search time is inversely proportional to prey density
Explanation:
Optimal foraging theory is a model used to predict animal behavior during the search of food, which is a critical process that requires the consumption of energy and time. In order to increase its fitness value, animals acquire foraging skills that help to obtain higher energy rates for the lowest cost. Thus, the optimal foraging model enables the prediction of the optimal strategy that allows to maximize the gain of energy during a particular time interval. The critical search time indicates the time that a consumer needs to add additional prey to its menu. In this model, a consumer will be converted to a 'generalist' and will add a second prey to its menu when the search time for the preferred prey is higher to the energy-time coefficient to obtain such prey.
