Many experiments on Earth's early atmosphere have resulted in the formation of organic molecules, but none have resulted in cell formation. In which of the following ways do the experimental conditions prevent cell formation in the lab? A: The ultraviolet light intensity of Earth's early atmosphere cannot be reproduced.

B: The gas composition of Earth's early atmosphere cannot be replicated.

C: The nutrients of Earth's early atmosphere are different from those found today.

D: The experiments cannot last for billions of years as conditions did in Earth's early atmosphere.

reposting untill i get the help i need -w-

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )

well the answer is 2!
