Impact of the use of fossil fuels during the industrial revolution was it made possible a huge increase in the amount of productive energy available to humans.
The development of machines, including steam engines and the internal combustion engine, made it possible to exploit vast new resources of energy stored in fossil fuels, specifically coal and oil. The fossil fuels revolution greatly increased the energy available to human societies during industrial revolution.
Contrary to this fossil fuel have some disadvantages like when fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

B :) :) :) :) :) :) :) :)
Explanation:
The genes that determine color and pattern are linked.
- Solid pattern allele (L) is dominant over lined pattern (l)
- Blue color allele (B) is dominant over aqua color (b)
<h3><u>Initial cross</u></h3>
Homozygous lined aqua beetle has the genotype <em>lb/lb</em>
It can produce only 1 type of gamete: <em>lb</em>
X
Homozygous solid blue beetle has the genotype<em> </em><em>LB/LB</em>
It can produce only 1 type of gamete:<em> </em><em>LB</em>
The F1 is formed by the union of the parents' gametes, so it will have the genotype <em>lb/LB</em>
<h3><u>F1 test cross</u></h3>
Test crosses involve a homozygous recessive individual.
<u>The homozygous recessive individual</u><u><em> lb/lb</em></u><u> can only produce 1 type of gamete:</u>
<u>The F1 individual </u><em><u>lb/LB</u></em><u> can produce 4 types of gametes:</u>
- lb - parental
- LB - parental
- lB - recombinant
- Lb - recombinant
Plants tend to grow where the light is coming from because the sun is there main energy source. this helps with plants growing in nature because in nature they will have all the sun that they need and will be able to grow faster
Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA.
During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs.
RNA polymerase moves from the 3' end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA.
Therefore, D. Nucleic acids attach to the bases in the DNA.
