Which statement below is an example of how a gamete's structure significantly helps its function?

Eggs have tails to help them travel down the fallopian tubes to the uterus.

Sperm have a well-protected head and a motor to help them travel.

Eggs are small to minimize their chances of double fertilization.

Sperm are large so that they can contain nutrients for the developing embryo.

The rate at which molecules water and oxygen can enter a cell is determined by the-

After fertilization, which type of cellular division is responsible for the growth and development of a complex, multicellular organism?

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.
