The Cuyahoga River in Ohio had been so polluted that it caught fire repeatedly from 1868-1969, including a 1952 fire that result

ed in nearly $1.5 million in damages. Amazingly, other rivers in the United States also caught fire during this period. The following question are about these fires.
Why didn't federal laws limiting pollution of rivers and streams prevent this pollution and these fires?
a. There were no federal regulations of water pollution at that time.
b. These industries that polluted the water had been repeatedly fined for polluting and simply continued to ignore the laws.
c. The federal laws preventing water pollution did not apply to this specific state, where this occurred.
d. This pollution went undetected by agents overwhelmed by the amount of work.

Answer: a. There were no federal regulations of water pollution at that time.

Explanation:  The Cuyahoga River in Cleveland was highly polluted by sewage and industrial waste from neighboring industrial firms in the 1960s. Inflammable materials were dumped on the banks and there was a film of oil on the water.  In June 1969, it caught fire from a spark on a train track and the resulted in a fire all over the river. It was not the first time this had happened but people had become more aware of the dangers of water pollution. The incident resulted in the launch of the Environmental Protection Agency. Before then, there were no federal regulations of water pollution .

In nuclear fission and fusion reactions mass is converted into energy. The average person in US uses around 100,000,000 J of ene
daser333 [38]

Answer:

a) The yearly energy consumption for a US population of 300 million is 3\times 10^{16} J/year

b) The energy that would be released if a 60 kg person were converted entirely into energy is 5.4\times 10^{18} Joules.

c) 180 years would this amount of energy support a population of 300 million.

Explanation:

a) Average energy consumed by single person of US = 100,000,000 J/year

Then 300 million US citizen will consume:

300 million = 300 × 1,000,000 = 3\times 10^8

The yearly energy consumption for a US population :

100,000,000 J/year\times 3\times 10^8=3\times 10^{16} J/year

The yearly energy consumption for a US population of 300 million is 3\times 10^{16} J/year

b) E = m\times c^2

E = Energy from converted mass of m

c = speed of light

Given mass of person = m = 60 kg

E=60 kg\times (3\times 10^8 m/s)^2 = 5.4\times 10^{18} J

c) Energy calculated in part (b) = E=5.4\times 10^{18} J

The yearly energy consumption for a US population  of 300 million in an year = 3\times 10^{16} J/year

Let the that would be supported by 5.4\times 10^{18} Joules of energy be x.

x\times 3\times 10^{16} J/year=5.4\times 10^{18} J

x=\frac{5.4\times 10^{18} J}{3\times 10^{16} J/year}=180 years

180 years would this amount of energy support a population of 300 million.

Amoebas are unicellular. The single cell splits in half to form two new cells. A student claims amoebas are alive. Is the studen
Norma-Jean [14]

Based on the fact that the single cell of the Amoeba can split in half, the correct answer is The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.

<h3>Why is the student correct about Amoebas?</h3><h3 />

An organism is considered to be alive due to various reasons and one of them is whether the organism has reproductive capabilities and can therefore reproduce and create offspring.

Even though the Amoeba is a unicellular organism, it can still reproduce asexually which means that it can reproduce without the need for another organism of its kind like it does when it splits itself in two.
