Answer:
hydrosphere and biosphere
Explanation:
The spheres of the Earth are lithosphere, biosphere, atmosphere, hydrosphere etc. Hydrosphere refers to the collection of all the water bodies on the surface of the Earth e.g oceans, lakes, rivers etc. On the other hand, biosphere refers to the collection of life on Earth e.g plants, animals, microbes etc.
In this question, Water availability is said to impact plant growth and the animals who depend on plants for food. These water availability and the living organisms (plants and animals) it impacts are interactions between the HYDROSPHERE AND BIOSPHERE.
Answer:
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function and behavior of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several techniques such as cell culture, various types of microscopy, and cell fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how cells function, ultimately giving insight into understanding larger organisms. Knowing the components of cells and how cells work is fundamental to all biological sciences while also being essential for research in biomedical fields such as cancer, and other diseases. Research in cell biology is interconnected to other fields such as genetics, molecular genetics, biochemistry, molecular biology, medical microbiology, immunology, and cytochemistry.
Explanation:
Answer:
sodium can form an ionic bond with fluorine
Explanation:
fluorine is f ;)
this happens because the sodium atom needs to lose an electron so the fluorine electron can join and create the bond.
