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.

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of

ziro4ka [17]

Answer:

Cell theory meets the definition of a scientific theory because it can be proven, it has been tested for a long period of time and therefore there are many evidences that support the theory but not enough to become a law. Well scientific laws are statements based on repeated experiments or observation, but also, a law is something that always applies under the same conditions. Evolution occurs in the characteristics of living things within a species overtime. . A theory is much more complex: it explains why something happens. A law only describes what happens.

The cell theory meets the definition of a scientific theory but i do not think it should be a scientific law.

Vlad [161]

Answer:

The hours are the independent variable.
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .
The domain is 0 to 30
The range is 0 to 330

Explanation:

The hours are the independent variable and should be plotted on the x-axis .

The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis

---------------

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:

+W+=+11h+

The domain is 0 to 30

( no hrs worked to 30 hrs worked )

The range is 0 to 330

( no wages eared to +11%2A30+=+330+ earned )
