When the human body (its cells) is exposed to radiation (X rays and gamma rays), electrons are emitted from atoms and molecules. ... ・These radicals react immediately with surrounding atoms, causing abnormal chemical reactions (or, minor damage to localized areas of cells).
The correct answers are as follows:
1. A.
There are basically two types of succession, they are primary and secondary succession. Primary succession refers to the type of succession that occurs in new and bare areas where the soil present is unable to sustain the growth of plants. An example of primary succession area is an area with sand dunes that is freshly formed. Primary succession usually occur over a long period of time. Secondary succession is a type of succession that occur on a land which was disturbed by hazardous events such as fire outbreak, flood, etc. Secondary succession occurs much faster than the primary succession.
2. D
There are two types of factors that affect any particular ecosystem, these are abiotic and biotic factors. The abiotic factors refers to non living factors such as temperature, relative humidity, rainfall, etc. while the biotic factors refer to the living factors. Looking at the options given above, one will see that only option D has living factor, which is predators. All other options have abiotic factors.

Answer:
Prophase, Meataphase, Anaphase and Telophase
Explanation:
Prophase-
The chromosomes begin to condense and the nuclear envelope breaks down.
Metaphase-
Pair of homologous chromosomes move to the eqautor of the cell.
Anaphase-
Homologous chromosomes move to the opposite poles of the cell.
Telophase-
Chromosomes gather at the poles of the cells. Cytoplasm divides.
