Scientists cultured and used Henrietta Lacks' Hela cells to conduct research. The cells were also used to determine the effectiveness of treatment for certain diseases,
However, normal cells may also be grown in a laboratory setting. An illustration of
normal cells are growing in a petri dish is shown below.
Cells placed in a petri dish will
continue to divide until the
spaces between the cells are
filled and the cells meet the
wall of the petri dish. A single
layer of cells is produced.
Any cells that are removed
will leave an empty space in
the petri dish.

Cells nearby will begin to
divide again until the spaces
are filled again
Which of the following is NOT reflected by this illustration and cell division of normal
cells?
Hi

Does mitochondria still meet the definition of a eukaryote why or why not?

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.

In general, are there any major differences that you can see? explain
