Earth's Greatest Enemies?Climatologist James Lovelock(originator of theGaia_hypothesis ) once said that Earth's greatest enemies

were cars, cows and chainsaws because of their contributions to destabilizing planetary climate.1. How do each of these things (cars, cows, andchainsaws) contribute to the destabilizing of Earth's atmosphere and climate? You must cite specificevidence from any Unit of the course to support your response. And...2. How are these three things connected to one another either by cause, effect or by solution. Consider all of the environmental concerns you have been learning about during the entire course and describe how these 3Cs as a group relate to one specific environmental issue (other than atmospheric destabilization).Reminder: Loss of land plants will not result in a reduction of atmospheric oxygen (because most of planetary photosynthesis and its resulting oxygen production is in the oceans).

Cars, cows and chainsaws are major polluters and their use must be regulated and limited, to reduce the emission of polluting gases into the atmosphere that can cause drastic climatic changes that harm the environment that we know intensely.

Although it is not widely publicized in the media and few people know about it, the chainsaw is a great villain of the earth's atmosphere, since its use releases large amounts of CO2 into the atmosphere, due to the burning of gasoline that these machines make to work. CO2, in addition to endangering the operator's life, is a gas that destroys the ozone layer and increases the effect of global warming. Not only does the chainsaw release this gas, but so do cars, which reinforces the need to use renewable fuels to be used in both cases.

Cows also release polluting gas, methane, which has a greater polluting potential than CO2. Methane is the result of the cow's digestive reactions, which release this gas into the atmosphere steadily. As herds of cows tend to be large, livestock becomes a major polluter, as herds result in a strong release of methane into the environment. This reinforces the need for increasingly stronger regulations for livestock, in addition to highlighting the importance of adopting alternative methods of feeding that reduce meat intake.

The ability to taste the chemical PTC is due to a single gene in humans.
Ganezh [65]

0:3:1

Explanation:

Tasters have the dominant allele for the itter taste of PTC, they can be homozygous TT and heterozygous Tt.

Non-tasters are supposed as autosomal recessive characters

they are homozygous recessive tt when expressed

Given in the equation two heterozygotes parents would produce offspring with the trait in the following ratio.

Tt (parent 1)

Tt (parent 2)

 If a punnet square is made

    T      t

T  TT    Tt

t    Tt     tt

The phenotypic character is in the ratio of 0:3:1

There will be 25% chances of recessive trait of non-tasters in the progeny of heterozygous parents.

Answer all parts of the question:
tamaranim1 [39]

Answer:

a. 0.03054 b. 0.000032 c. sorry I am not perfect

Explanation:

  • a. In the number 0.03054 , you need to move the decimal point two places to the right to get to 3.054 (which is between 1 and 10). Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied 3.054 by 10−2 . Think about it: 3.054×10−2=0.03054 .
  • b. Answer: 0.0000302 Step-by-step explanation: When 10 is to the power of a negative number, "move" the decimal dot left. 10⁻⁵ means to "move" the decimal 5 times to the left. 1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02). 0000003 . 02 2. Count 5 place values over. 00←0←0←0←0←3 . 02 3. Put the decimal behind the digit. 00 . 0000302 4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal. 0.0000302           <= Final answer 
  • c. sorry but I am not perfect at this
