a. true
b. false

The correct answer is A, as the statement is true. Miller and Urey performed an experiment that showed that organic molecules coud be made from inorganic compounds.  

Explanation:

The Miller and Urey experiment represents the beginning of experimental abiogenesis and the first verification that organic molecules can be formed spontaneously from inorganic substances under simple suitable environmental conditions. It was carried out in 1953 by Stanley Miller and Harold Clayton Urey at the University of Chicago. The experiment was key to supporting the theory of the primordial soup in the origin of life.

According to this experiment, the synthesis of organic compounds, such as amino acids, must have been easy on primitive Earth. Other researchers - following this procedure and varying the type and amounts of the substances that react have produced some simple components of nucleic acids and even ATP. This experience opened a new branch of biology, exobiology. Since then, new knowledge about DNA and RNA, prebiotic conditions on other planets and the announcement of possible bacterial fossils found in meteorites from Mars (such as ALH 84001), have renewed the question of the origin of life.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
