How is a light element like helium is formed in stars and how is a heavier element like gold formed by stars? YALL HELP ME WITH THIS PLEASE 1. Elements are not formed in stars. All elements were formed during the Big Bang and no elements have been formed since then.

2. Both light and heavy elements are formed only under very high energy conditions, such as a supernova.

3. Only light elements like helium are formed by stars. They are formed from the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold cannot be formed under any condition.

4. A light element like helium is formed by the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold form under very high energy conditions, such as a supernova, when helium atoms combine under enough successive collisions to form very heavy elements.

Awater molecule is polar because there is an uneven distribution of these between the oxygen and hydrogen atoms.

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.
