Answer:
enzymes don't affect the free energy of the reactants or products
Explanation:
That is, they don't change whether a reaction is energy-releasing or energy-absorbing overall. That's because enzymes don't affect the free energy of the reactants or products. Instead, enzymes lower the energy of the transition state, an unstable state that products must pass through in order to become reactants.
Answer:
The answer is "galaxies."
Explanation:
The "universe" is also called <em>"the cosmos."</em> It includes space, time and heavenly bodies such as<em> planets, sun, moon, galaxies, etc. </em>
A galaxy is considered to be a big collection of gas, dust, stars (including their solar systems). All of these are being held together by<em> "gravity." </em>The Earth's galaxy is called the<em> </em><u><em>"Milky Way."</em></u> The name is derived from how it appears from afar.
<em>Other than our galaxy, there are millions or even billions of other galaxies in the universe!</em> They come in different colors, shapes and sizes. They appear clustered together due to <em>"mutual gravity."</em> A cluster consists of hundreds to thousands of galaxies.
The best explanation for this unchecked population growth is that the predators are too few to slow down population growth of mussels. The environment limits population growth by changing birth and death rates. The factors affecting population size and growth include biotic factors such as food, disease, competitors, and predators and abiotic factors such as rainfall, floods, and temperature. Predators affect individual growth rates of surviving prey by acting to increase growth rate by thinning the density of prey populations, which releases survivors from competition.<span />
