Answer:
c. Osmosis is the diffusion of water molecules across a selectively permeable membrane.
Explanation:
Osmosis is the passive transport of water molecules from the region of their higher concentration to that of lower concentration through a semi-permeable membrane. Osmosis does not include the movement of solutes. When two solutions with different concentrations of solutes are separated by a semi-permeable membrane, water moves through the membrane from a hypotonic solution to the hypertonic solution until equilibrium is obtained. This process is called osmosis.
An isolated colony on a selective medium is not considered a pure culture because inhibited organisms might be masked by the colonies. This statement is true.
On the basis of their constitution or usage, culture media can be classified into various groups; these include defined, complex, selective, as well as enrichment medium.
A selective medium consists of dyes or noxious substances/chemicals which inhibit the growth of specific microorganisms but promote the growth of other microbes.
A pure culture is a laboratory culture which contains a single species of microorganism. It is free from other microorganisms.
Since selective media affects the growth of distinct organisms differently, therefore, an isolated colony formed in such type of medium is not considered a pure culture.

Answer:
<h2>retroactive interference.</h2>
Explanation:
Interference theory is a type of theory that explains the human memory. On the basis of certain characteristics, memory is classified as long term memory and short term memory. When some memories are deleted or forgotten from long term memory then such type of memory can not be retrieved by short term memory due to interfering with each other. Thus interference can be grouped as proactive and retroactive interference or learning.
In the case of retroactive interference, when some events or learning are going on then it is impossible to learn or retrieve some other things. So Marcus' difficulty can be explained by retroactive interference.
