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.

Alternation of generations in angiosperms the diagram below illustrates the alternation of generations that is characteristic of the angiosperm life cycle. label structures and processes (using white labels), indicate whether different structures are haploid or diploid (using pink labels), and indicate the types of cell division that occur at different points in the life cycle (using blue labels). drag the labels to their appropriate locations on the diagram of the angiosperm life cycle. labels can be used once or more than once. use only white labels for white targets, pink labels for pink targets, and blue labels for blue targets. a. meiosisb. haploidc. mitosisd. ametophytee. pollinationf. meiosisg. haploidh. mitosisi. ametophytej. fertilizationk. zygotel. diploidm. sporophyte
