The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.
Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.
Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.
With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.
Answer:
The correct answer is - option B. 19 mg/kg soil.
Explanation:
Phytoremediation is a process of the bioremediation that uses different plants to transfer, remove or destroy the contaminants from the soil. Cd is one of the contaminants that are removed or destroyed by the process of the phytoremediation.19 mg/kg soil is the concentration was available in the soil prior to the phytoremedaition took place.
Thus, the correct answer is - option B.
Eukariotic cells have nuclei, while prokaryotic cells do not.
The answer is; B
This genotype is similar to that of one parent. It assumes that nondisjunction of chromosome did not happen and there was no fusion of gametes. The offspring cannot have exact genotype as one parent in sexual reproduction, In sexual reproduction, the offspring gets half of its chromosomes from each parent. This is why the chromosome number is reduced by half in the formation of gametes through the process of meiosis.
