Overexposure of animals to x-rays is dangerous because x-rays are known to damage DNA A result of this damage

Question

1. unusually thick cell walls

2. no organelles located in the cytoplasm

3. abnormally large chrloplasts

4. changes in chromosome structure

Answer 1

I bet you got this **** from PETA. They care more about animals than ****** people. If they were given the choice to save an animal or save a human they'd save the animal.

Answer 2

4 = chromosome changes. If an oncogene is activated, it might result in cancer. Massive damage results in cell death. If enough cells die, this could kill the animal.

Answer 3

just to put this out there...humans ARE animals (even if we are a special kind of animal)

Answer 4

4. Changes in chromosome structure.

X-rays are very high energy rays, much higher than light and ultraviolet rays. They are also very short waves. These properties enable them to travel through barriers such as our skin (but not thick ones like lead). When they travel through skin and into our cell they come into contact with our DNA. DNA molecules then get excited by this intense energy and can break as a result.

Usually when DNA 'breaks' the cell automatically 'self-destructs'. This shouldn't be a problem for very small exposures, we can deal with a few cells lost. Prolonged exposure increases our chances greatly of breaking the DNA in places that regulate cell division. If the cell cannot regulate cell division it can lead to serious consequences like cancer.
