Answer:
Paleontologists have uncovered new fossils from Tiktaalik roseae, which, while still a fish, is considered a transitional fossil that also has traits common to the first four-footed animals. This more complete picture of Tiktaalik suggests that the creature had strong, mobile hind fins.

what is the standard form of 12,341 us?
Answer:
12341 in standard form = 1.2341 × 10⁴
Explanation:
When you split the number 12341 into a coefficient and a power of 10 you do get 12341 in exponential form, but there is an indefinite number of possibilities.
As you probably want 12341 in normalized scientific notation, the coefficient or significand of 12341 in scientific notation must be in the interval [1,10[.
As there are many ways to express 12341 in scientific notation, in this post we mean 12341 in normalized scientific notation, unless stated otherwise. Therefore:
12341 in scientific notation = 1.2341 × 10⁴.
This can also be expressed as 1.2341 × 10⁴, using the caret symbol, or as 1.2341e+4, which is called 12341 in e-notation.

A. letting your beliefs influence your results
B. avoiding plagiarism of the works of others
C. making up data to support a special cause
D. copying the work of other scientists and claiming it as your own
Answer:
Avoid plagiarism and the work of others
Explanation:
I took the test and got it right. Hope this helps :)
Avoiding plagiarism of the work of others shows that you have intellectual honesty. So the correct option is B.
What is plagiarism?
The act of presenting someone else's ideas or work as your own, with or without that person's agreement, by integrating it into your work without giving it due credit, is known as plagiarism. This definition applies to all works, both published and unpublished, whether they are in manuscript, print, or electronic form.
Plagiarism can be willful, careless, or accidental. Plagiarism that is deliberate or careless is prohibited under exam regulations and is grounds for disciplinary action. In addition to text, additional media such as computer code, pictures, graphs, etc. must also include credit for the ideas and works of others.
It equally applies to both published and unpublished text and data taken from books and journals, lectures, theses, and other students' writings. Text, information, or other materials that you take from websites must also be credited.
Learning and using the rules of good academic practice from the start of your university career is the best way to prevent plagiarism.
Therefore the correct option is B.

Explain what is meant by the term "excited state" as it applies to an electron. Is an electron in an excited state higher or lower in energy than an electron in the ground state? Is an electron in an excited state more or less stable than an electron in the ground state?
Answer:
Excited state of an electron is the state attained by an electron after it has absorbed energy and it moves further from the nucleus.
an electron is at higher energy when excited and at lower energy when at ground state.
an excited electron is less stable due to the decrease in the nuclear force of attraction and the grounded electron is more stable due to it's close distance to the nucleus.
An electron in excited state has its electron present in higher energy level while an electron in ground state is present in lower energy level.
What is an energy level ?Electrons present in an atom revolve in different orbits which are stationary states and are also called as energy levels. The energy levels are numbered as integers which are also called as principal quantum numbers.
Energy of the stationary state is given as E= -R
1/n² where R
is the Rydberg's constant. When an electron is excited, and it moves from lower to higher energy levels there is absorption of energy, while when it moves from higher energy level to lower energy level it radiates or gives out energy in the form of radiation.
They can also be defined as the distances between electron and nucleus of an atom . Electrons present in K energy level have least energy .Energy level diagrams are studied to understand nature of bonding , placement of electrons in orbits and and elemental behavior under certain conditions.

Which waves have the highest frequencies?
A. microwaves
B.UV
C. waves with the lowest energy
D. waves with the highest energy
Answer:
D. Waves with the highest energy
Explanation:
The more energy the higher the frequency. More specifically there will be more energy per photon.
Microwaves are on the low end of the electromagnetic spectrum while UV is higher but there are more waves with more energy such as gamma rays.

The density of ice is 0.92 g/cm3 and the density of rubbing alcohol is 0.80 g/cm3. If an ice cube is placed in a container of rubbing alcohol, the ice cube will
Question 7 options:
a) float in the rubbing alcohol with none of the ice cube submerged.
b) sink to the bottom of the container.
c) move up and down in the rubbing alcohol.
d) float in the alcohol so that most of the ice cube is below the surface of the liquid.
Answer:
Option B. Sink to the bottom of the container.
Explanation:
From the question given above, the following data were obtained:
Density of ice = 0.92 g/cm³
Density of rubbing alcohol = 0.80 g/cm³
From the density of both substance given, we can see clearly that the ice has a higher density when compared with the rubbing alcohol.
Thus, If an ice cube is placed in a container of rubbing alcohol, the ice cube will not float rather, it will sink to the bottom of the container because the ice has a higher density than the rubbing alcohol.

The density of a liquid substance is 0.95 g/mL. Three students calculated the density as 0.56 g/mL. Calculate the percent
error.
Answer:
The answer is 41.05 %Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question we have
actual number = 0.95 g/mL
error = 0.95 - 0.56 = 0.39
We have
[tex]p(\%) = \frac{0.39}{0.95} \times 100 \\ = 41.0526315...[/tex]
We have the final answer as
41.05 %Hope this helps you

The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 768 g
volume = 24 cm³
We have
[tex]density = \frac{768}{24} \\ [/tex]
We have the final answer as
32 g/cm³Hope this helps you
Answer:
The density of wood is 32 g/cm³.
Explanation:
Given data:
Mass of wood = 768 g
Volume of wood = 24 cm³
Density of wood = ?
Solution:
Density is equal to the mass divided by its volume.
Formula:
d = m/v
d = density
m = mass
v = volume
d = 768 g/ 24 cm³
d = 32 g/cm³
The density of wood is 32 g/cm³.
