How are gamma rays made? Also, how are they important?
Answers
Gamma rays are given off by stars, and by some radioactive substances.
They are extremely high frequency waves, and carry a large amount of energy.USES-Because Gamma rays can kill living cells, they are used to kill cancer cells without having to resort to difficult surgery.This is called "Radiotherapy", and works because healthy cells can repair themselves fairly well when damaged by gamma rays - but cancer cells can't. Getting the dose right is very important!There's also targeted radiotherapy, where a radioactive substance is used to kill cancer cells - but it's a substance that'll be taken up by a specific part of the body, so the rest of the body only gets a low dose. An example would be using radioactive iodine to treat cancer in the thyroid gland.

1. Nucleus: Contains genetic material, controls cell activities.
2. Mitochondria: Produces energy through cellular respiration.
3. Golgi apparatus: Modifies and packages proteins.
1. Nucleus: The nucleus controls the cell by storing DNA instructions. It affects cell growth, reproduction, and metabolism by regulating gene expression.
2. Mitochondria: Cellular respiration powers mitochondria. They convert foods into cell energy source ATP. Metabolism and cell signalling depend on mitochondria.
3. Golgi apparatus: It changes and packages endoplasmic reticulum proteins and lipids. Cisternae are stacked membranous sacs. The Golgi apparatus adds carbohydrates or lipids to proteins, organises them into vesicles, and guides them within or outside the cell. It is crucial for intracellular transport and secretion.

During this reaction, the oxidation number of Fe changes from
(1) +2 to 0 as electrons are transferred
(2) +2 to 0 as protons are transferred
(3) +3 to 0 as electrons are transferred
(4) +3 to 0 as protons are transferred
Answers
let oxidation state of Fe = x
2x + (-2 * 3) = 0
2x - 6 = 0
2x = +6
x = +3
Oxidation state of Solid Iron
Fe
the rule is that the oxidation state of an uncombined element is zero
Redox pertains to electron transfer and not proton transfer thus your answer is OPTION 3 (+3 to 0 as electrons are transferred)
