Answer:
The scientists was able to come to the conclusion that certain organisms have common ancestor because she was able to study and see the skeletal structures of extinct species and compare them with modern day species, and they had a big resemblance.
The skeletal structure is something that needs a lot of time to change, millions of years. Even then, the basics of the structure will be the same, with the further modifications in place on top of it. It is something that is very useful when comparing extinct species and modern day species, as it can give a nice clue about their connection and common ancestry.
The cats for example, the modern day ones and the first ones that appeared, have almost the same bone structure, where even a trained eye finds it hard to find a difference, and that is a very nice clue about tracing the ancestry.
The term evolution refers to the changes that occurred as organisms changed from earliest forms to their present forms. Evolution shows that complex life forms emerged from simple life forms.
The evidence that the scientist observed that led her to believe that certain organisms have a common ancestor is that she observed a fossil with skeletal structures similar to certain modern organisms.
Explanation:
They would likely conclude that certain groups of organisms have the same ancestor after looking at the bones and structure.
What are fossils?A fossil is a dead preserved remains of the organisms and their bodies are buried in sediments that were formed under ancient lakes and waters.
After looking at the strcture of bines and the scientists can come to the conclusion that these four fossils were of the same species and that they differ from the modern-day ones. Cabon dating and isotopic data can show us the time of origin.

If r is a solution to the equation f(x)=0, name three additional statements that can be made about f and r assuming f is a polynomial function.
If r is a solution to the equation f(x) = 0, then the correct statement is; r is a real zero of the polynomial function f, r is an x-intercept of the graph of f and x - r is a factor of f.
What is a Polynomial Function?A polynomial function of degree N will have a total of N roots. These roots may even be complex conjugate pairs but if there are real roots, then the polynomial will have a linear factor with that root.
Thus, If r is a solution to the equation f(x) = 0, the correct statement that can be made about f and r assuming f is a polynomial function is that;

Which similarity postulate or theorem correctly identifies the triangles’ relationship?
The similarity theorem that identifies the given relationship correctly is:
B). AABC - ADEF by SAS Similarity Theorem
What is SAS Similarity postulate?The SAS similarity Theorem states that in the situation where the ratio shared by the sides of two triangles remains the same and one of their angles stays equal, both the triangles would be similar.
In the given two triangles, ΔABC and ΔDEF we see that;
the ratio of the sides are:
BC/AB = EF/DE
5/15 = 4/12 = 1/3
and,
∠B = ∠E = 86°
Since the ratios shared by the two sides are equal in both the given triangles and one angle is equal, the triangles are the same.
Thus,

Consider a regular hexagon inscribed in circle C with radius r. Regular hexagons have six congruent sides and six congruent angles. In the figure, angle CAB measures 60°.
What is m∠ACB?
✔ 60
°
What is the length of segment AB?
✔ r
What is the perimeter of the hexagon?
✔ 6r
The perimeter of the hexagon is
✔ slightly less than
the circumference of the circle.
The circumference of the circle is
✔ slightly greater than 6r
Explanation:
Based on the information given, angle ACB is equal to 60°.
Given the following data:
Angle CAB = 60°How to calculate m∠ACB.Form the diagram, we can deduce that CA is equal to CB and it is the radius of the circle. Therfore, ∠CAB = ∠ACB = 60°.
Since the triangle is an equilateral triangle, the length of segment AB is equal to the radius of the circle because all the sides of an equilateral triangle are equal.
Also, since one of the six (6) arcs of the hexagon is measured as radius (r), then its perimeter is equal to 6r.
Furthermore, the perimeter of the hexagon is slightly less than the circumference of the circle because the circumference is longer.
In conclusion, the circumference of the circle is slightly greater than 6r.

How is the information in dna passed to a molecule of mrna? describe this process
The information in DNA is transmitted to the mRNA by the process of transcription.
What is transcription?The process by which data from the DNA is transferred to the mRNA is known as transcription. A messenger molecule called mRNA transfers information from the DNA to the tRNA so that it can be translated. Initiation, promoter, elongation, and termination are the steps that transcription takes.
Pre-mRNA transcripts are created during transcription by the enzyme RNA polymerase (green), which uses DNA as a template (pink).
The pre-mRNA gets transformed into a mature mRNA molecule, which can then be translated to produce the protein molecule (polypeptide) that the original gene intended.
Therefore, the information in DNA is passed to a molecule of mRNA through transcription.

How are refraction and diffraction similar? how are they different? check all that apply
Explanation:
they are diffrent cause refraction is solid and diffrection is liquid
Refraction involves the bending of waves through a medium, and diffraction involves the bending of waves around an object. The correct option is 4.
What is refraction?Refraction is the bending of light as it travels through transparent materials. We are able to create lenses, magnifying glasses, prisms, and rainbows because to this bending caused by refraction.
Diffraction and refraction both entail the bending of waves, which makes them comparable. The way this bending happens in them varies, though.
Refraction is the bending of waves as they travel through different media. The wave bends when it passes through various media due to the variations in speed.
Contrarily, diffraction involves the bending of waves as they move through or around an obstruction. As a wave runs into an opening or an object's edges, it stretches out and bends, which causes it to diffract.
Thus, the correct option is 4.

This theory of emotion suggests that first a specific physiological response to stimuli is experienced, and the emotion that results is an interpretation of this unique physiological "code"
James–Lange theory is a physiological theory of emotion that explains that emotions are created in response to experiences and stimuli, where the autonomic nervous system creates physiological responses.
What is James–Lange theory?It is a theory proposed independently by William James and Carl Lange, which suggests that emotions occur as a consequence of physiological reactions to events.
For this theory, emotions are processes that involve a series of triggering conditions or relevant stimuli.
Therefore, we can conclude that the James–Lange theory explains the origin of the components of emotion and where physiological activation plays an important role in the existence of an emotional response.

It takes 12. 5 ml of a 0. 30 m hcl solution to neutralize 285 ml of naoh solution. What is the concentration of the naoh solution?
Answer: M₂ = 0
Explanation:
HCl + NaOH — NaCl + H2O
For acid base titrations:
M₁ V₁ = M₂ V₂where lower-script 1 and 2 are the molarity and volume for acid and base respectively.
M₁ = 0.30 M
V₁ = 12.5 ml
M₂ = (unknown)
V₂ = 285
0.30 x 12.5 = 285 M₂
M₂ = 3.8/ 285
M₂ = 0
p.s I think there is an error with the typed question. It’s not possible to use 285 ml of base against 12.5 ml of acid.
