The right answer is analogous structures.

It is nevertheless interesting to note that several years before, a competition took place rather quickly between two types of mammals: the placentals and the marsupials, the Evolution having given in each of these two groups also armed individuals as we will see it next (We speak then of parallel evolution, that is the acquisition of similar characteristics in two species occupying the same space, not to be confused with a convergent evolution which gives identical attributes to two populations existing at times or in different ecosystems).

Fungsionalisme adalah?​
Vlada [557]

Answer:

Teori adalah suatu pendapat bagaimana dan kenapa sebuah fakta terjadi. (Macionis, 1997:15). Sedangkan Scupin dan De Corse (1995)mendefinisikan teori adalah kumpulan hipotesis yang tidak berhubungan yang menawarkan penjelasan secara umum untuk fenomena natural atau sosial. Salah satu teori Antropologi adalah fungsionalisme.

Teori fungsionalisme adalah teori dominan dalam antropologi. Teori ini memandang budaya sebagai satu kesatuan, dan mencoba untuk menjelaskan bagaimana hubungan antara bagian-bagian masyarakat yang tercipta dan bagaimana bagian ini fungsional (bermakan memiliki konsekuensi yang menguntungkan pada individu dan masyarakat) dan disfungsional (bermakna memiliki konsekuensi negatif). Teori ini memandang masyarakat sebagai sistem yang kompleks yang mana bagian tersebut bekerja bersama untuk mempromosikan solidaritas dan stabilitas; ini menandakan bahwa kehidupan sosia kita dituntun berdasar pada struktur sosial, yang pola perilaku sosialnya secara relatif stabil (Macionis, 1997)

Seluruh struktur sosial berkntribusi pada operasi masyarakat. Dua antropolog inggris terkemuka Radcliff Brown dan Bronslaw Malinowski, menggambarkan dua standar teori: Struktural fungsionalisme, yang menekankan pada keunggulan dari masyarakat dan menyusun para individu, dan bagaimana berbagai macam elemenfungsi struktur sosial untuk memelihara permintaan sosial dan keseimbangan. Dan Psikologi strukturalisme, yang mana menekankan pada kbutuhan individual untuk bertemu dengan masyarakat.

Kelemahan teori fungsional adalah gagalnya menjelaskan kenapa masyarakat itu berbeda atau justru memiliki kesamaan. Ontropolog fungsionalisme menganggap dunia tertib, memberi sedikit perhatian atau bahkan tidak memberi perhatian pada kompetisi dan konflik (Howard dan Dunaif-Hattis, 1992). Teori ini tidak berhubungan dengan sejarah, mengabaikan proses sejarah. (Scupin dan De Corse, 1995) teori ini juga tidak dapat menjelaskan perubahan sosial dan budaya, sebagaimana ia dulu memandang masyarakat sebagai sesuatu yang stabil dan tetap. meskipun memiliki kelemahan, teori fungsionalisme mempengaruhi perjanjian besar penelitian empirik dalam antropologi.

Control of (blank) synthesis is the key to controlling the chemical pathway of the cell.
strojnjashka [21]
Controlling the synthesis of proteins is the key to controlling the chemical pathways in the cell.
This is because proteins have key roles in many chemical reactions in the cell.
The most important proteins for the chemical reactions in the cell are enzymes.
Enzymes catalyze many chemical reactions, therefore, the control of the enzyme synthesis is a direct way of controlling other chemical reactions in the cell.
