Incoming solar radiation relates to climate because the more solar radiation the hotter it will get. When energy trapped in the atmosphere warms the land, ocean and air.
<span>The number of electrons in the valence shell of an element is the principal determinant factor of the kind of chemical bonding it will be involved in. For an element that has only one electron in its outermost shell, such an element will donate the electron to another element which need only one electron. Thus, such an element will undergoes electrovalent bonding. For an element which have four electrons in its outermost shell, such element will prefer to share the electrons will other elements who need such in order to become stable, thus, such element will undergo covalent bonding.</span>
Answer:
95%
Explanation:
The complete question is as follows:
The lethal tumor dose is defined as the dose that will eradicate what percentage of the tumor yet preserve normal tissue?
a) 85%
b) 95%
c) 65%
d) 75%
- Radiation dose is used as a therapy of cancer as the radiation leads to the breakage of the DNA and hence, renders the cell incapable of growth and division.
- Lethal tumor dose is defined as the dose of radiation that is required for the production of complete eradication of tumor.
- The dosage of the radiation depends on the sensitivity of the target tissues to radiation along with the size of the tumor.
- The lethal tumor dose is defined as the dose that will eradicate 95% of the tumor however it would still preserve the normal tissue.
