Answer to Question 1

Radioactive emissions are the direct products of fission; they are generally unstable isotopes of their respective elements. The unstable isotopes become stable by ejecting subatomic particles (alpha particles, beta particles, and neutrons), or high-energy radiation (gamma rays), or both.
Exposure to radiation increases the risk of cancer. Low doses of radiation may damage DNA. Some people argue that there are doses of radiation below which there would be no adverse effect because of the DNA repair mechanisms that exist. Others argue that no safe level of exposure exists. High doses of radiation can block cell division, resulting in death.

Answer to Question 2

Interspecific competition is competition between species, while intraspecific competition is competition within a species. Interspecific competition occurs when ecological niches overlap. Intraspecific competition occurs because members of the same species are competing for the same resources. Intraspecific and interspecific competition are forms of environmental resistance that limit a population size because these types of competition result from density-dependent biotic and abiotic factors that are necessary for survival.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
