Why are the Miller-Urey experiments essential to the theory of evolution? They showed that life can only come from life. They sh

owed that electricity can create life. They showed how organic molecules could be made from Earth's early atmosphere. They demonstrated the role that natural selection played in the evolution of modern day organisms.

The correct answer is -They showed how organic molecules could be made from Earth's early atmosphere.

Urey calculated that the early Earth atmosphere was reducing and the early atmosphere contained methane, ammonia, hydrogen and water. Based on the conclusion of Urey, Stanley Miller did an experiment and synthesizes organic compounds such as amino acids, fatty acids, hydroxyl acids and amide products from the constituents of the then reducing atmosphere as suggested by Urey.

Your first cousin died of tay-sachs disease (autosomal recessive, incidence 0.09%). you are not affected, nor is anyone else in
AlexFokin [52]
<span>25%

   Starting from my First cousin family, I know for sure that the Uncle is is a carrier (Aa) and he must have married a wife who is also a carrier (Aa) and that is how they got an affected son. Thus, this leads to the fact that either both of my grandparents are carriers (Aa x Aa) or only one of them is a carrier (Aa x AA). As a result, the chances that my mom (who is related to the uncle who has a defected child) is a carrier is either (2/3 or 1/2) depending if my grandparents genotype, respectively. Thus, if my mom chances of being a carrier is 1/2 then my chance of being a carrier is 1/4. (given that my dad is not a carrier b/c CF is a rare disease) However, if my mom chance of being a carrier is 2/3 then my chance of being a carrier is (2/3)x(1/2)=(1/3) As a result, I could either be 1/4 or 1/3. But since the answer only provide the choice of 1/4 and not 1/3. This leave 25% is the correct answer.</span>

Which component is affected when a catalyst is added to a chemical reaction? the amount of substrate the activation energy the a
mote1985 [20]

The right answer is the activation energy.

The catalyst increases the reaction rate by introducing new reaction paths (mechanism), and lowering its activation energy, or activation Gibbs free energy. By doing this it can increase the speed, or lower the temperature of the reaction. It is important to note that the catalyst does not alter the total Gibbs free energy of the reaction which is a system state function and therefore has no effect on the equilibrium constant.
