When a cat drops from a tree to the ground, the conversion of takes place. Then cat runs up behind a mouse to obtain its food. After eating its prey, the conversion of takes place inside the cat’s body

Answers

When a cat drops from a tree to the ground the conversion of gravitational potential energy to Kinetic energy takes place.

After eating its prey the conversion of Chemical to mechanical energy takes place.

Energy conversion

Energy is neither created nor destroyed rather it is transformed/converted from one form to another. when the cat is at rest on the tree it possesses a potential energy but at it falls to the ground the potential energy is converted to a kinetic energy. Also

As the cat consumes the rat the energy absorbed from the consumption of the rat is converted to mechanical energy which enables the mobility of the rat.

Hence we can conclude that the conversion of energy is as listed above.

If scientist were to find 4 fossil that appear to be of the same ancestor, what can be concluded?

Answers

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?

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

Answers

During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

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.

Based on the compression of the spring and the speed, the following are true:

The factor by which the spring's potential energy is increased is = 4.The factor of increase in speed = 2.

What is the factor of increase in potential energy?

Potential energy is found as:

= 0.5k x (2 x compression²)

= 4 x 1/2kx²

The 4 shows that the potential energy increases by 4 times.

What is the factor of increase in speed?

Initial speed is:

Which similarity postulate or theorem correctly identifies the triangles’ relationship?

Answers

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,

ΔABC is similar to ΔDEF

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"

Answers

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.

Answer:  M₂ = 0

Explanation:

HCl + NaOH — NaCl + H2O

For acid base titrations:

M₁ V₁ = M₂ V₂

where 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
