Answer:
A 'big' idea in science is one that applies to a range of related objects or phenomena, whilst what we might call smaller ideas apply to particular observations or experiences.

Answer:
Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. It was an important step in the movement away from spontaneous generation.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
The first of these tenets is disputed, as non-cellular entities such as viruses are sometimes considered life-forms.

All matter whether solid, liquid, gas has a chemical formula or elemental symbol.
Filtration may work, there are many types of filters capable of filtering specific types if compounds.
Because you can get ill if your body temperature goes too high or too low, for example oh can get heat stroke if it’s too high and hypothermia if too cold.
