<span>Characteristics of Enzymes : *Enzymes Made out of proteins and RNA. *Shape related to the function, names usually end in ase, catalyst. functions of enzymes is speed up chemical reactions by lowering the activation energy . Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.</span>
Answer:
i would probally ask them why they dont think its real. I would honestly try to understand. And then i would show them graphs (online of course) about how its affecting the planet and if they still dont listen id probally just fight them
Explanation:
Answer:
The answer is B. Some organic molecules, including amino acids, could have been produced from chemical reactions on early Earth.
Explanation:
Miller-Urey Experiment:
The Miller-Urey experiment was an attempt to explain the origin of life on Earth. Miller-Urey simulated the primordial soup i.e. the environment of primitive Earth to prove the spontaneous generation of organic molecules. The conditions they introduced included:
- A methane-ammonia-hydrogen and water mixture that exactly simulated the primordial soup.
- A spark of 70,000 volts that simulated lightening.
- A temperature of 800 degree Celsius.
Observations:
- After running for 18 days, the final solution was examined for presence of organic molecules.
- Miller-Urey observed that most of the methane and ammonia had been consumed and the mixture contained carbon monoxide and nitrogen.
- The solution further contained 25 amino acids (mainly, glycine, alanine and aspartic acid)
, several fatty acids
, hydroxy acids and amide products.
The experiment concluded that simple organic compounds such as amino acids could have been formed through spontaneous generation under the Earth's primitive environmental conditions.
Answer:
Yes
Explanation:
Yes, the impact on one species over time can impact ecosystem.
An ecosystem is consist of biotic and abiotic organisms. There is a major relationship between biotic and abiotic or biotic and biotic components.
The relationship between biotic and biotic components is called food chain, in which one organisms depends on others for their survival and balance the energy flow in the ecosystem. So impact on any one species in the food chain will impact the whole ecosystem.
For example: Plants are the producers in the food chain, and if plants will be impacted or destroyed over time, the consumers depending on the plants will die from starvation and disturb the energy flow in the ecosystem. Along with this, plants are also related to abiotic factors such as maintenance of oxygen and carbon dioxide in the atmosphere, so the balance of these gases will also get disturbed.
Hello :)
I believe its during the 2nd trimester
Hope this helps :)
