The most appropriate answer to this question is the second option, exothermic. The more energy is being given off for forming new bonds than is needed to break the original bond in an exothermic reaction.
<span>Natural selection is when
species learn to adapt to their environment. They could (1) differential
reproduction, that is, not all organisms are able to reproduce to their fullest
capacity because nature cannot simply sustain it and (2) acquire genes, that is
heredity. Certain characteristics of organisms tend to survive if it continues
to strive. If it survives, this trait is passed down to the next generations
forgetting the other traits but only the one who could survive the environment.
Therefore it is true that <span>natural selection is when
‘organisms inherit advantageous traits, and tend to reproduce more successfully
than other organisms’</span></span>

Answer:
1. 1.26823082 mL
2. 0.5 g/mL
Explanation:
The density formula is:
1.
Rearrange the density formula for v,
<em>Multiply both sides by v.</em>
<em>Divide both sides by d.</em>
Volume is found by dividing mass by density. The mass is 20 grams and the density is 15.77 grams per milliliter.
Substitute the values into the formula.
Divide. Note the grams, g, will cancel.
2.
Use the density formula.
Density is found by dividing mass by volume. The mass is 10 grams and the volume is 20 milliliters.
Substitute the values into the formula.
Divide.
