PLEASE PLEASE: select a correct answer for blank one and blank two from the options I have posted below <3

A black hole begins to form as an aging star abruptly collapses when it ceases(1)
This occurs after the star has consumed its component elements in this order(2)

1.
Increases its gravitational force

Emitting radiation from fusion reactions

Generating heavy metals

Gaining mass by collecting gas and dust

2.
Iron carbon and helium

Hydrogen helium then through iron

Silicon helium hydrogen

Carbon iron then helium through hydrogen

Molecular models of two different substances are shown below. in the molecule on the left, the oxygen atom pulls on electrons more strongly than the hydrogen atoms. in the molecule on the right, the two oxygen atoms pull on the shared electrons with the same strength. water molecule, h,o oxygen molecule, oz when the two substances are put in the same container, they do not attract each other. why does this happen? a. they both contain oxygen. b. one is polar and one is nonpolar. c . they are both polar. d. they contain different elements.

In general, characteristics that an organism survive and reproduce become more common over time. what mechanism of evolution causes this?

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
