European Starlings have a significant impact on their environment because they congregate in such large numbers. They probably play a role in seed dispersal because of their consumption of a wide variety of fruits. European Starlings also control some insect populations, but since they will eat almost anything they cannot be relied upon to eat only pests. Insects they are known to feed on include the larvae of craneflies (Tipulidae) and moths (Lepidoptera) as well as mayflies (Ephemeroptera), dragonflies and damsel flies (Odonata), grasshoppers (Orthoptera), earwigs (Dermaptera), lacewings (Neuroptera), caddis flies (Trichoptera), flies (Diptera), sawflies, ants, bees and wasps (Hymenoptera) and beetles (Coleoptera). They will also eat small vertebrates such as lizards and frogs, as well as snails (Gastropoda) and earthworms (Annelida). European Starlings have a particular technique of inserting their closed bill into the ground or an object and then prying the bill open, creating a small hole. This allows them to forage efficiently in soil and among roots as well as in feed troughs and on the backs of ungulates where they search for ectoparisites.
Answer:
d a discrete combination of traits, for example Masaai cattle herding.
Explanation:
A cultural complex consists of different cultural traits that together create a 'culture'. Thus, a cultural complex can be defined as a group of cultural traits that are functionally interrelated. A cultural trait can in turn be defined as any acquired knowledge that is learned by social interaction and interpersonal relationships. Moreover, a cultural pattern occurs when cultural traits and cultural complexes associate each other in functional roles.
The answer are the hands and feet. It is the continuously changes of the
characteristics of the body, most noticeable in height and weight. The ages 13-15 and 17-18 the two major brain
growth spurts occur. In times of growth spurts the changes is visible during the
first year of puberty.
Explanation:
In the early days of development, in an embryo, the cells are pluripotent and can differentiate into any kind of cell of the organism. As the embryo develops, autocrine and paracrine signaling between the cells of the embryo causes the cells to migrate to particular regions of the embryo and begin differentiating into respective parts of the organism. This signaling causes differential silencing of particular genes of the cells depending on the type of cells they will differentiate into. As the embryo develops into a fully grown organism, these cells lose potency (except for stem cells) and become fully differentiated into respective limbs or organs of the organism.
