Running cars on electricity would conserve gasoline because electric cars do not use the same resources.

Hope this helps!

Answer: A) conserve gasoline.

Fueling the cars with electricity offers some benefits over conventional fueling  cars, these vehicles react quickly, these can be charged easily and efficiency of the vehicle increases. Most importantly this initiative  can help in the conservation of the fuels like coal, natural gas and gasoline which are non-renewable sources of energy. All these energy resources utilized by the cars or any other transportation vehicle releases toxic chemical gases which are responsible for pollution. The running cars on electricity is likely to produce less pollution than conventionally fueled cars.

A scientist could use DNA as a molecular clock to do which of the following? (2 points)
ad-work [718]

Explanation:

<u></u>

<u>-to determine how long ago two species of animals shared an ancestor</u>

<u></u>

The molecular lock describes a method which utilizes mutation rates for DNA over time, to determine the divergence of two species sharing common ancestry,due to evolution. Along with  genetic drift, selective mating and natural selection, evolution may occur within populations due to spontaneous heritable changes to DNA, called mutations, over time.

Further Explanation:

During reproduction, other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.
