Answer:
Give up.
Explanation:
Physics is horrible.
And that's the cold hard truth. :(
Answer:
I'd say 2) "Genes are instructions that cells use to create proteins." Because it's more specific, and that's essentially what it's for.
The first evidence that gravity outside our solar system worked the same way as it does inside is that Herschel measured the two stars that make up the Castor system moved around each other
<h3>What is a Solar system ?</h3>
The Sun, eight planets, their moons, comets, asteroids, meteoroids, and dwarf planets make up a solar system, which revolves around the Sun. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets that revolve in a particular order around the Sun.
- Although there are more than 3,200 other stars in our galaxy with planets around them, our solar system is the only one that is formally referred to as a "solar system."
- The closest stellar system to our solar system, Alpha Centauri, is one of the brightest stars in the southern skies and is only 4.3 light-years away.

Explanation:
Answer:
Option (B) is correct.
Explanation:
Given that the molecules of hydrogen gas () react with molecules of oxygen gas () in a sealed reaction chamber to produce water ().
The governing equation for the reaction is
From the given, the only fact that can be observed that 2 moles of and 1 mole of reacts to produce 2 moles of .
As the mass of 1 mole of grams ... (i)
The mass of 1 mole of grams ...(ii)
The mass of 1 mole of grams (iii)
Now, the mass of the reactant = Mass of 2 moles of + mass 1 mole of
[ using equations (i) and (ii)]
grams.
Mass of the product = Mass of 2 moles of
[ using equations (iii)]
=36 grams
As the mass of reactants = mass of the product.
So, mass is conserved.
Hence, option (B) is correct.
