Answer: a. Genetically significant dose
Explanation:
Genetically significant dose is the index of radiation that is received by the genetic pool. It determines the progeny of the given population. This can be achieved by weighting the individual dose of the gonads that is received by the x-ray examination or ionization imaging by the individuals being examined also by the contribution of those persons to the expected number of children to be born in future.
It represents an estimate of the genetic significance of gonad radiation doses.
Answer: after clear cutting of the forest
An ecosystem can be defined as biological community where living and non-living components interact. The clear cutting refers to the cutting of the trees and plants in the forests, for using the wood product, medicines obtained by these plants and trees. The forests which is being clear cut will be disturbed. The animals and birds species will migrate to different location in search of food and habitat. The clear cut forests can be restored as the soil is fertile enough to support the growth of new plants. The colonization of new plants will take place with the already present precursors like seeds, roots and partially trees. The animals and birds species will soon immigrate after colonization of tree and plants species. Therefore, the ecosystem will repair itself with the help of these precursors.
Answer:
Acaso pocos conceptos sean tan difusos y abarcativos como la diversidad, entendida en sí misma como una abstracción que hace referencia a la abundancia de las diferencias. En efecto, la variedad y la falta de semejanza parecen implícitas en todo aquello que nos rodean y en nosotros mismos, quizás haciendo énfasis en la importancia de la diversidad.
