Answer: The Miller-Urey experiment falls short of demonstrating that life can arise from inorganic molecules in that: It doesn't show a leap between a collection of amino acids and a single-celled organism

Answer:

Explanation:

Miller and Uray experimented with methane, ammonia, and carbon dioxide in a laboratory condition. Then he keeps them in an experiment environment and applied high electric current to this mixture of 3 gases. After the passing of electric charges in this gas mixture, the molecules are split. After some time this results in another element such as oxygen, amino acids, and water.

Water, amino acids, and water are the essential components of life. Every living animal cell has amino acids and they need water, oxygen for their survival.  

His experiment shows life arose from non - living components. Because in this experiment he created the environment of the beginning of the earth's atmosphere. At that time no oxygen and water were there. Heavy lighting causes the splitting of the methane, ammonia gases along with co2. This creates water and oxygen and also cause heavy rainfall. This rainfall continues for several years to cool down the hot earth. Then the holes of the earth filled the forming ocean and new life arose in it.

That's why Miller and Urey's experiment shows life arose from nonliving things.

Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,
Colt1911 [192]

Answer:

G=21 %

T= 29 %

A= 29 %

Explanation:

Since C only binds to G, you have the same amount of C and G, so G is 21 %.

100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.

So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A

Can anyone give a paragraph answer to what global footprint means! Thank you.
pochemuha

Answer:

The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy.[2][3][4] It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment.

Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has been using natural capital 1.7 times as fast as Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.7 planet Earths.[1][5]

Ecological footprint analysis is widely used around the world in support of sustainability assessments.[6] It enables people to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations.[2]

3.Why is the surface of the Earth in constant motion?
tekilochka [14]
3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move. 

4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea. 

5.  An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption. 

6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter. 

7. Depends on what kind you're looking for. I'd look it up for your specific topic.

8. To apply a forces to something, usually resulting in a stretch.

9.  The action of compressing something, to flatten or squeeze by pressure

10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.

11. In areas undergoing extension or stretching. It's when the crust is extended. 

12.  The hanging wall drops relative to the footwall. 

13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
