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.

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

Explanation:

Public policy begins with identifying an issue. Then, government officials form a solution. and  Finally, a government agency implements the solution.

What is Public policy?

Governmental bodies create laws, set policies, and distribute funds in every society. A system of rules, regulations, courses of action, and financial priorities involving a specific subject that have been established by a governmental body or its representatives is known as public policy.

People and organizations frequently make an effort to influence public policy through advocacy, education, or the mobilization of interest groups.

In Western-style democracies, public policy is clearly shaped differently from how it is in other systems of government. But it is logical to suppose that competing interest groups would always make an effort to sway policymakers in their direction.

Therefore, Public policy begins with identifying an issue. Then, government officials form a solution. and  Finally, a government agency implements the solution.

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.

What is the factor of increase in potential energy?

Potential energy is found as:

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

What is the factor of increase in speed?

Initial speed is:

Charlie earns an annual salary of $61,870. If he is paid weekly, how much would his gross pay be each week?

Answers

In a year, there are total 52 weeks usually, so annual salary is weekly salary times 52. Charles' weekly pay is given by: Option d: $1,189.81

How to count the number of ways in a year?

A year contains approx 365 days usually (leaving leap years)

A week contains 7 days.

Dividing 365 in group of 7s, we get:

(1 as remainder, 52 as quotient), so one day is left only) (this is not always the case that there would be 52 weeks only, there can be sometimes 51 weeks due to some incomplete weeks).

(for general case, we will assume there are 52 weeks in an year).

For the considered case, it is specified that:

Annual salary of Charles = $61,870

There are 52 weeks in an year, so, dividing his salary in 52 parts, we get his weekly salary as:

For acid base titrations:

where lower-script 1 and 2 are the molarity and volume for acid and base respectively.

M₁ = 0.30 M

M₂ =  (unknown)

V₂ = 285


0.30 x 12.5 = 285 M₂
