1when a single cell of e. coli reproduces, it first duplicates its dna. next, the cell elongates as each copy of dna is pulled toward opposite ends of the cell. the membrane then pinches inward, dividing the cytoplasm into two halves and producing two daughter cells. what is true about these daughter cells?

The question is incomplete, the complete question is:

When a single cell of E. coli reproduces, it first duplicates its DNA. Next, the cell elongates as each copy of dna is pulled toward opposite ends of the cell. the membrane then pinches inward, dividing the cytoplasm into two halves and producing two daughter cells. what is true about these daughter cells? a. they are genetically different from the parent because they are produced by sexual reproduction. b. they are genetically identical to the parent because they are produced by sexual reproduction. c. they are genetically identical to the parent because they are produced by asexual reproduction. d. they are genetically different from the parent because they are produced by asexual reproduction.

THE CORRECT ANSWER IS C

Explanation:

This process that E. coli bacteria undergoes is called BINARY FISSION. This process of binary fission is a form of asexual reproduction which bacteria uses to reproduce or add to their population. Binary fission is a form of cell division, similar to mitosis that occurs in eukaryotic cells.

As highlighted above, the bacteria cell first replicates its DNA (in its nucleoid) at a spot on the circular chromosome called ORIGIN OF REPLICATION. After replication, the duplicated chromosomes get pulled apart to the opposite ends of the cell. After which the membrane pinches inward to form a SEPTUM (dividing new wall). The septum splits down the middle, releasing the two daughter cells as individual bacterium.

This process is a form of asexual reproduction similar to mitosis in the sense that two identical daughter cells are produced i.e. genetic variation does not occur.

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
