How does the hypothesis of microspheres and the rna world hypothesis build off of each other?
a. microspheres were important for storing and releasing energy for surrounding organisms that contained rna.
b. nonorganic molecules self-replicate within the early microspheres, similar to the way cells divide.
c. replicating rna molecules transformed into dna within the microspheres.
d. when microspheres split, the genetic coding in self-replicating rna would pass to the newly formed microspheres.

Why is it incorrect to say that mitochondria function only as energy factories with cell

What makes a dominant allele different from a recessive allele

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
