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.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
