3.Commercial development in the U.S. has resulted in an increase in the number of roads, housing developments, shopping centers,
Art [367]

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.

_________ is (are) the product of Transcription, and the starting material of Translation. A. tRNA B. Amino Acids C. mRNA D. Rib
Andreyy89

Answer:

C. mRNA

Explanation:

Hello,

In this case, we may remember that when DNA is undergoing transcription a specific sequence is copied via the RNA polymerase in order to produce the messenger RNA which is subsequently used as the starting material of translation for the protein synthesis as shown on the attached picture. Thereby, answer is C. mRNA, since the transcription process produces it and then, for the translation process, it contains the codons which promote the formation of polypeptides (proteins) via the connection of the anti-codons contained in the tRNA which also provide the amino acids for the polypeptides formation.

Regards.
