When is osmosis used by cells to move water across a selectively permeable
membrane?

A. Osmosis is used by cells when large molecules pass freely across the selectively permeable membrane.

B. Osmosis is used by cells to create equilibrium when large molecules can't pass through the membrane.

C. Osmosis is constantly in process inside of a cell, regardless of equilibrum.

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.

According the inverse square law, doubling the distance from the source of the sound, a speaker, for example, will drop the sound 6 db each time. if you were standing in the back of an auditorium, 32 feet away from a speaker not using any amplification, would you be able to hear a speaker clearly? why or why not?

Bio molecules are essential to all living things. which biomolecule is “d” from the table
