Answer:

a) legs

Explanation:

Based on these characteristics it can also be said that this species would have legs. This is due to this new species having paired lateral fins. That is because paired lateral fins refer to the pectoral and ventral fins, which are corresponding to the fore and hind legs of the higher animals. Meaning that this new species would have had to have legs if they had paired lateral fins, and a bony skeleton would help corroborate this finding.

<em>The correct option is C) A mouse and a human have about the same number of genes.</em>

Explanation:

The technique of genetic sequencing has enable us to learn and compare thee genomes of different organisms. Genome sequencing proves that the genome of the humans and mice are about 99 percent similar. The number of genes in the mouse genome and the genome of humans is almost equal.

Other options, like option A, cannot be true because many complex organisms have fewer chromosomes than other organisms. For example, there are many simple plants which have more number of chromosomes than the complex humans.

What evidence is there that the endangered species act is causing harm to species????
Juliette [100K]

Answer:

There is strong and increasing evidence the Endangered Species Act is causing widespread harm to the species it is supposed to protect-to the extent the Act may be doing more harm than good. The Act makes otherwise normal and legal forms of land and resource use illegal, such as farming, home building and cutting timber. The Endangered Species Act’s severe penalties-$100,000 and/or 1 year in jail for harming a single species or even unoccupied habitat that is deemed suitable-turn species in to liabilities. As a result, landowners seek to reduce their liabilities in a number of ways.
