Answer:
With millions of different kinds of organisms in the world, scientists must find order in all of this diversity. Scientists group living organisms into one or more of a few major categories as part discipline known as taxonomy. The bodies of organisms are organized into functional systems—cells are organized into tissues, and tissues are organized into organs. Body systems carry out critical functions, such as locomotion, reproduction, digestion, and circulation. All living things on Earth are composed of the same carbon-based, molecular building blocks.

Answer:
The correct options are MACROPHAGES AND NEUTROPHILSE.
Explanation:
Majority of the white blood cells in humans are specialized phagocytic cells, examples of these are macrophages, neutrophilse, monoctyes, mast cells and dendritic cells. The major functions of phagocytic cells is to protect the human body from disease pathogens. They do this by ingesting foreign bodies that are found in the body. Macrophages and neutrophilse are the major phagocytic cells in the body, they are the principal effector of non-specific host defense and inflammation.
Answer;
-The most appropriate answer is Lipids
Explanation;
-Lipids is among the four biological biomolecules, the others being proteins, carbohydrates and nucleic acids.
-Lipids are made up of fatty acids and glycerol and are composed of elements carbon, hydrogen, oxygen and they may also contain phosphorus, like in the case of phospholipids which are mainly components of the cell membranes.
-They take two forms, namely; fats and oils. Therefore, the oil form of lipid may be used as lamp oil.
