What hypothesis did Miller-Urey test in their experiment?A. Organic molecules can form in a reducing atmosphere.
B. Earth is a primordial soup.
C. Organic molecules cannot survive in a reducing atmosphere.

Answers

Answer 1
Answer: The answer s the option B. Earth is a primordial soup. They tested Oparin's theory which states that the life (organic matter) can be formed from inorganic compounds. They placed a mixture of compounds that are supposed to be present in Earth before life started, which are CO2, methane (CH4) and water (H2O), hydrogen (H2) and nitrogen (N2) in a closed vessel and used electric discharges (to simulate the effects of the storms that happened in Earth without atmosphere). Then they analyzed the products obtained and indeed found organic matter. Yet, this does not mean that life is definetly originated in this form.

What is the mass of an aluminum cylinder that has a volume of 1.50m3

Answers

Answer: The mass of aluminium cylinder is 4065 kg.

Explanation:

Density is defined as the ratio of mass of the object and volume of the object.

Mathematically,

\text{Density}=\frac{\text{Mass of the object}}{\text{Volume of the object}}

We are given:

Density of aluminium = 2710kg/m^3

Volume of aluminium cylinder = 1.50m^3

Putting values in above equation, we get:

2710kg/m^3=\frac{\text{Mass of aluminium cylinder}}{1.50m^3}\n\n\text{Mass of aluminium cylinder}=4065kg

Hence, the mass of aluminium cylinder is 4065 kg.
Aluminium density: 2700g/m^3

therefore; 2700g/m^3 X 1.50m^3 = 4050g = 4.05Kg

Just use the units of density (mass/volume) and the units of what's given to figure it out :)

Question #21TrueFalse The general name for a substance added to a reaction that affects the rate but is not consumed in the reaction is called a complex a. True
b. False

Answers

The statement above about “The general name for a substance added to a reaction that affects the rate but is not consumed in the reaction is called a complex” is false. The answer is letter B. It should be the enzyme, not the complex.

Rainforests are principally responsible for global oxygen turnover true or false

Answers

Answer:

False

Explanation:

Rainforests are very important for global oxygen movement, but they are not the main element for oxygen movement.

Seaweed is the real lung of the world, it is primarily responsible for the global movement of oxygen as it produces more oxygen through photosynthesis than it needs in breathing, and the excess is released into the environment. Rainforests release much less oxygen into the atmosphere worldwide, as most of the gas produced is consumed in the forests themselves. However, rainforests are extremely important and should not be destroyed.
