<span>star is born when clouds of dust and elements are gathered together in a certain space due to gravity, more and more mass and therefore pressure builds. when the pressure becomes enough to overcome the electronic repulsive force between two hydrogen nuclei, they are forced together and massive amounts of energy are given off forming helium atoms. this energy is then used to fuse other nuclei together. this could be compared to the way human life starts, where instead of 2 nuclei joining together to start a life cycle, two gametes, or sex cells are joined together. </span>
It should be B because theories explain why something happens.
Answer:
the correct answer is number (1)
Explanation:
this number is the one who refers to the continental shelf because as you can see it refers to an area which is a shallow water area and near from the continent . and the continental shelf is exactly this area , it is defined as a continent which is under an area of a shallow water of the sea which we can called shelf sea
number 2 refers to continental slope and it defines as the steep slope which connect between the continental shelf and the sea floor

Answer:
0.05142 M
Explanation:
Let's consider the neutralization reaction between KHP and NaOH.
KHC₈H₄O₄ + NaOH → H₂O + NaKC₈H₄O₄
12.39 mL of 0.04150 M NaOH were required for the neutralization. The moles that reacted are:
12.39 × 10⁻³ L × 0.04150 mol/L = 5.142 × 10⁻⁴ mol
The molar ratio of KHP to NaOH is 1:1. The moles of KHP that reacted are 5.142 × 10⁻⁴ mol.
5.142 × 10⁻⁴ moles of KHP were in 10 mL of solution. The concentration of the KHP solution is:
5.142 × 10⁻⁴ mol / 10 × 10⁻³ L = 0.05142 M
