What are biologically determined, innate patterns of behavior? drives impulses instincts releasing behaviors universal behaviors
Akimi4 [234]

Instincts are the biologically determined, innate patterns of behavior.

Instincts are the intuitive feeling of a person towards a certain stimuli. These are inborn impulses. There are 6 basic human instincts. These are seeking, anger, fear, panic-grief, care, pleasure and play. Amongst all, seeking is considered to be the most powerful instinct.

Innate behavior is the habit that is present inside an organism by birth, may be genetically. No prior learning or experience is required for it.  Examples of the same are: reflexes, taxis and kinesis, fixed action patterns and circadian rhythms. When a baby suckles after birth, it is an innate behavior.

To map genes of a bacterial strain, conjugation must be interrupted at given times. Suppose you have Hfr cells of genotype a+b+c
OLEGan [10]

Answer:

The answer is not in any of the options and is the following:

to eliminate any remaining Hfr cells.

Explanation:

In a medium that has a streptomycin antibiotic it is used to kill Hfr donor cells after the conjugation is interrupted. This is entirely due to the streptomycin sensitivity allele (str-s) which are found in Hfr strains. The presence of the streptomycin resistance allele, located in the receptor, is used for the specific destruction of Hfr donor cells after conjugation occurs.
