Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)
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:
It increases ecosystem productivity, protects fresh water resources, and provides nutrient storage and recycling
True. Greenhouse gases are composed of many molecular components that provide and are necessary for life to still exist on earth. For example, the carbon dioxide and the others alike. However, when these exceed the necessary level and amount in the atmosphere, they cause tremendous increase in temperature.
