Answer: New growth is stricken with the blight before it has the chance to mature.

Explanation:

American Chestnut trees can indeed regrow from their roots but due to the devastating effect of the chestnut blight, they have been unable to do this since the blight spread across the country.

The blight was introduced when Chinese chestnut trees were imported into the U.S. in the 20th century. It killed off most of the chestnut trees in the U.S. and attacks the tree again when it grows to around 6 meters bringing it down to its roots. This is why the American Chestnut is considered endangered.

svetoff [14.1K]

Answer:

The summer sun increases the temperature and hence volume of air in the balloon resulting in the balloon bursting. On the other hand, the winter cold decreases the temperature and hence volume of air in the balloon resulting in the balloon shrinking.

Explanation:

According to the Charles' gas law, an increase in temperature at constant pressure is proportional to volume.

Also, according to Gay-lussac's law, an increase in temperature at constant volume is proportional to pressure.

When thr inflated balloon is left in the summer sun, the temperature of the gas in the balloon increases and so does the pressure. This increase in pressure will only be relieved by expansion of the balloon which eventually results in it bursting.

In the winter on the hand, the temperature of air in the balloon decreases and so does the pressure of the gas. Therefore, the volume of the gas in the balloon will become smaller and the balloon will shrink in size.

Which is an example of a substitution mutation?

rjkz [21]

Answer:

CAT - GGC - TAC mutates to CAT - GGC - TAG is the right answer

Explanation:

because substitution mutation is the change in the single base which result in change in codon which encode different amino acid and protein sequence changes.

for example in this

CAT - GGC - TAC encodes HGY protein

now after change in single nucleotide from C to G

CAT - GGC - TAG which encodes HG stop codon

which fossil fuel has had the most significant influence on human transportation over the last centrury?

givi [52]

Answer:

Oil is the world's primary fuel source for transportation

Explanation:

Fossil fuels mainly coal, Oil and natural gas are the world's primary energy source. Fossil fuels formed from Organic matter over millions of years.

Oil is a source of transportation and it is obtained from the underground reservoirs. Then the crude oil is refined to obtain fuel oil, liquid petroleum, gasoline etc. Crude oil also used to make other products such as pesticides,fertilizers etc

Coal is used to generate electricity. Around 30% of the power supply in United states mainly due to coal. China is world's largest producer of coal and supplied to all over the World.

Natural gas also used to generate electricity, commonly used in buildings and industries.
