What is any energy resource that can be used in place of fossil fuel’s called

Biology
2 answers:
Masja [62]3 years ago

I think those are usually called "alternative fuels", or

"alternative energy sources".  Those are things like

wind, solar, hydro, geothermal, tidal, nuclear etc.

I don't like that description at all.  It makes it sound as if

there's something about them that's not quite right, and

that we don't really take them seriously.

The only thing that makes them "alternative" is that we're

just now discovering them, for the first time since we left

the caves.  

Up until now, we've always been happy to burn the stuff

that's cheap and easy to get from a hole in the ground.  

But we're just now starting to notice that it's poisoning

the air we breathe, and plus, so many people have been

using it for so long that now, it's becoming harder to get.  

So we're starting to look around now and see what else

we can use to do the job.

Through conservation programs that plans for individual species to more species of entire faunas of a particular location also boost population size and prevent hunting of threatened or endangered species in both realms.

Overtime, genetically modified fishes which can develop resistance to diseases are introduced to the realm.

Moreso, waste channels through which pollutants gets into the water bodies are well-treated for safety of fishes.

Give two reasons why dna evidence analysis is an imperfect science
Virty [35]

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.
