if all cells in an organism have the same DNA, the same genes why are there so many different types of cells in the human body for example there are nerve cells and skin cells and muscle cells
Answers
Answer:
The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.[2] Most plant and animal cells are only visible under a light microscope, with dimensions between 1 and 100 micrometres.[3] Electron microscopy gives a much higher resolution showing greatly detailed cell structure. Organisms can be classified as unicellular (consisting of a single cell such as bacteria) or multicellular (including plants and animals).[4] Most unicellular organisms are classed as microorganisms.
The number of cells in plants and animals varies from species to species; it has been estimated that humans contain somewhere around 40 trillion (4×1013) cells.[a][5] The human brain accounts for around 80 billion of these cells.[6]
Cells were discovered by Robert Hooke in 1665, who named them for their resemblance to cells inhabited by Christian monks in a monastery.[7][8] Cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all living organisms, and that all cells come from pre-existing cells.[9] Cells emerged on Earth at least 3.5 billion years ago.[10][11][12]

what is half-life of mercury-203
Answers
Answer:
The correct answer is - 47 days approximately.
Explanation:
In this given graph is the decay graph of mercury-203, there is a representation of the relation of change in the amount of the mercury -203 with the time in days. The red arch is showing the change of parent isotope percent with elapsed time and the green dashed arch showing the daughter isotope percentage with isotope.
The half-life is the required time to decay an element to half of its inital amount, according to the definition the half-life of parent isotope mercury-203 is the amount where the red arch is present at 50% in the graph that is 47 days approximately.

Someone answer me please
Answers
Answer:
Due to mutation.
Explanation:
The genotype and phenotype of circled offspring is different from the non-circled offspring because it has different genetic makeup, that is responsible for its different color. The change in the circled offspring's genotype was caused by a mutation. Mutation is a change that occurs in the DNA sequence, or genetic makeup of an organism due to mistakes when the DNA is copied or environmental factors such as UV light and smoke etc.
