What is a fossil?
Fossils are fossilised (petrified) remains of animals/plants. A fossil though, is only a fossil, when it is from a different geological era.
How does that relate to evolution?
Evolution and fossils are very related. When we scan the DNA of different fossils, we find that the DNA can be similar to living species we have today, which helps us trace back their origins.
Tracing back a species origins is not something we do just to see how that species changed along time. When we manage to make an evolutionary chart of a species, we know how they changed, what they changed, and maybe not more, but very importantly, when the previous species were extinguished. If we know when they were extinguished, we can find out what caused that extinction:
- A lack of adaptation.
- Lack of resources.
- Temperature changes.
- Increase of predators.
- Deadly migrations.
- Other natural disasters.
So, in other words, by studying one species, we can study our own planet.

Answer:
Overall DeltaG = -6.40 kJ/mol
Delta G = 31.6 - 6.4 =25.2 KJ
T = 17 + 273.15 =290.15 K
Delta G = -RT * Ln (K)
25.2 * 10^3 J = -(8.314 J/moles*k)(290.15K) * Ln (K)
So (Delta G)/(-RT) = Ln (K)
Ln K = -10.44643114
Thus k = 2.905 *10^-5
Question: Which employee is most likely to come up with creative solutions?
A.) Dana is in awe of her boss and does not contradict him.
B.) Mark loves interacting with all types of people.
C.) Nina follows a linear, systematic approach to all problems.
D.) Omar hesitates to voice his thoughts during meetings.
E.) Sara approaches every situation with lessons learned from her experiences.
Answer:
"Sara approaches every situation with lessons learned from her experiences." likely to come up with creative solutions
Explanation:
Creative Solutions are given by a person who understands the company's project, can draw appropriate solutions to their goals, with creativity exceeding the expectations of investors and consumers. An employee with a profile to create creative solutions is one who can handle adverse situations and through his experience find effective solutions. Among the options given in the question, the employee who best fits this requirement is Sara.

The structural level in which the muscle produces the contraction is known as the muscle fiber.
<h3>What is a muscle fiber?</h3>
A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.
This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).
In conclusion, the structural level in which the muscle contracts is the muscle fiber.
