Question

Составьте последовательность возникновения структур животных в ходе эволюции: 1)грудная клетка 2)диафрагма 3)фасеточные глаза 4) вторичная полость 5)нервная система диффузного типа

Answer 1

1) Грудная клетка - у Пресмыкающихся

2) Диафрагма - у Млекопитающих

3) Фасеточные глаза - у Насекомых

4) Вторичная полость - у Кольчатых червей

5) Нервная система диффузного типа - у Кишечнополостных

---------------------------------------------------------

Процесс эволюции животных выглядит так:

Кишечнополостные → Кольчатые черви → Насекомые → Пресмыкающиеся → Млекопитающие

Значит,последовательность структур будет таким в ходе эволюции:

нервная система диффузного типа → вторичная полость → фасеточные глаза → грудная клетка → диафрагма

ОТВЕТ: 5,4,3,1,2

Answer 2

Sequence of Evolutionary Development of Animal Structures

1) Нервная система диффузного типа (Diffuse Nervous System): - The earliest form of nervous system in animals is the diffuse nervous system, where neurons are spread throughout the organism without forming a centralized brain. This type of nervous system is found in simpler organisms like cnidarians and flatworms. - Source: Source 2) Фасеточные глаза (Compound Eyes): - Compound eyes, such as those found in insects, are believed to have evolved around 540 million years ago. They are made up of multiple photoreceptor units called ommatidia, providing a wide field of view and high motion sensitivity. - Source: Source 3) Вторичная полость (Coelom): - The evolution of the coelom, a fluid-filled body cavity, is a significant development in animal evolution. It provides space for organ systems to develop and allows for greater body complexity. Coeloms evolved in triploblastic animals, appearing in some groups around 600 million years ago. - Source: Source 4) Грудная клетка (Thoracic Cavity): - The thoracic cavity, which houses the heart and lungs, is a feature of more complex organisms with a closed circulatory system. It likely evolved in early vertebrates, allowing for more efficient oxygen transport and metabolic processes. - Source: Source 5) Диафрагма (Diaphragm): - The diaphragm is a muscular structure separating the thoracic and abdominal cavities in mammals. It is a relatively recent evolutionary development, believed to have appeared with the emergence of early mammals around 300 million years ago. - Source: Source This sequence represents a broad overview of the evolutionary development of these animal structures, showcasing the progression from simpler, early forms to more complex, specialized adaptations over millions of years.
