Explanation:
1. relationship between plants, animals, and the environment --- d) ecology
Ecology is the study that is part of biology, and it focuses on the interaction between living organs and their preservation. It is trying to explain various processes, interactions, evolution, developments, movements, but also succession and abundance of living organisms in the environment. Besides organisms, ecology studies involve communities, ecosystems, population, and biosphere, and all the interactions around these things. The main goal is the improvement of understanding the interaction, and therefore the improvements in the relationships between the living creatures so that all may live in harmony and without causing hazards.
2. the structure and origin of the earth --- a) geology
Geology studies the earth, rocks, and soils that make up the solid parts of our planet. It researches energy, water, and mineral resources found on the earth. This also involves studies of the processes and reactions of these elements, including the problems of climate changes and natural disasters (volcanos, earthquakes, floods, landslides, etc.). It can also involve studying all these processes and elements on the planets and universe bodies that are not the Earth, such as Mars or Moon.
3. the universe and celestial bodies --- b) astronomy
Astronomy is the science that studies various celestial bodies - stars, planets, meteors, comets, galaxies, etc. - that compose the universe outside of Earth's atmosphere. This includes observational astronomy (study by observing through the telescopes and cameras and drawing the conclusion from the observations) and theoretical astronomy (using mathematical methods to study, research and draw the conclusion of development and existence of celestial bodies)
4. interaction between different types of matter --- c) chemistry
Chemistry is a science dealing with different matters, compounds, molecules, elements and atoms, and their interaction, structure, and composition. It researches how all these elements change and interact in certain reactions with each other and with the energy. There are different kinds of chemistry - biochemistry (processes that occur in the living organisms), physical chemistry (combination and reaction of energy with chemical substances and elements), organic chemistry (researching carbon and the compounds involving it, which means living, organic beings which have carbon molecules), inorganic chemistry (studying compounds without carbon) and analytical chemistry (observation, research, and measurement of chemical substances and elements - it is involved in all other branches)
5. humans and the development of culture --- d) anthropology
Anthropology is the science that studies people, society and culture, how they develop, compare and interact, and how they react to the events in the modern, globalized world. Anthropology includes various types of research, such as medical and material (like forensic anthropology and archaeology), or empiric study (such as linguistic and socio-cultural anthropology). It deals with many different aspects of humankind - the pre-industrial society, development, and comparison of different cultures, as well as the modern, urbanized life of various industrialized countries.
