Question 1
nuclear processes which involved the splitting of a heavy nucleus into 2 nuclei with smaller mass numbers is called
fusion
nuclear chain reaction
spent rods
fission

question 2
when u-235 absorbs a neutron and becomes the unstable nucleus of u-236, this is the beginning of a(n)
a chain reaction
nuclear fusion
spent rods
exothermic reaction

question 3
nuclear power plants use the principle of
exothermic reactions
spent rods
nuclear fusion
controlled nuclear fission

question 4
two serious negatives about nuclear power plants:
1. a potential meltdown of the plant releasing huge amounts of radiation
2.
hard to find safe nuclear waste disposal of radioactive materials that are radioactive for thousands of years
unleashed chain reactions
nuclear fusion
critical mass

question 5
biological effects of exposure to radiation include:
1. the penetrating ability of the radiation into tissues
2.
uncontrolled chain reactions
nuclear fission
nuclear fusion
the ionizing ability of radiation to affect cell functions

Quickly! brainliest if two people answer! 1. the blood has red blood cells, white blood cells and platelets. red blood cells carry oxygen to other cells in the body. cells need oxygen to live. white blood cells destroy certain germs. they protect our bodies from disease. which question is answered in this paragraph? (a) what is the role of blood vessels? (b) what type of cells are attached to bones? (c) what type of blood cell to clot your blood? (d) what are the different types of blood cells? 2. which sentence from the section "stem cells" best explains the role of stem cells? (a) when one kind of cell stops working, stem cells can . (b) they can turn into that cell and take its place. (c) scientists are studying new ways to use stem cells. (d) these cells can people heal faster. 3. read the selection from the section "nerve cells." nerve cells send messages to the rest of our bodies. these messages move between the brain, spinal cord and various organs. nerve cells are also called neurons. fill in the blank. a "neuron" is a (a) cell that moves information from the brain to other parts of the body (b) stem cell that has both an axon and a dendrite (c) cell that controls the fingers of a body (d) cell that makes up the spinal cord 4. some muscles in our body move without us telling them to. these are called involuntary muscles. some examples are the cardiac muscle cells inside the heart. these cells the heart relax and fill with blood. what is the best definition of "involuntary" based on the context clues? (a) something that happens on its own (b) trying hard to do something (c) something moving back and forth (d) easily moved
