Answer:

The correct answer is c) a chemical change, because a gas was produced.

Explanation:

Sometimes when performing scientific experiments in laboratories, chemical changes are obtained in the elements that have been used, a chemical change is an alteration in the structure of a compound, so the element is different than at the beginning of the experiment.

Generally, when there is a chemical change this is usually irreversible; For example, in the case of Nio, he experiments with yeast, water, and sugar, which puts it in a bottle and closes it with a balloon, this mixture of substances has resulted in a chemical change since the element is transformed in gas.

At the age of 66, Hilda is worried when researchers ask her to take an IQ test. She knows that older people are assumed to have
GrogVix [38]

Answer:

The answer to the two questions here would be thus:

1. Which term is used to describe Hilda´s anxiety? would be: stereotype threat. Stereotype threat is a situation in which a person may feel threatened by a certain circumstance, or condition which will make evident the differences to which that person has become accustomed due to their race, gender, or age group.

Hilda is a 66-year-old woman who has become accustomed to believing that she will not perform well on an IQ test, because stereotypically, society, and Hilda herself as part of that society, believes that people her age are less skilled at such tests than younger ones. So her body responds through anxiety, which is a form of stress, to the threat, which is the IQ test.

2. Hilda´s test performance will be affected because her own mind and her body are in "fight or flight" mode, which means that the sense of threat will hinder the true capacity that her brain has, despite any differences, to sift through a problem, and find a solution to it. Hilda is ignoring the fact that her brain´s capacity will not necessarily be affected by age, and therefore she will not give it a chance to exert its full capacity to solve the issue.

Compared to what you know about the methods of disciplines such as mathematics, the natural sciences (e.g., biology, chemistry),
Damm [24]

Answer:

Humanities can be tough to run experiments on especially when trying to find inspiration for a book, a poem or painting.

Explanation:

There are alot of comparison between science disciplines and that of humanities. the culture is different and sciences can be very competititive and mechanistics. techniques are used to solve puzzles in science.

Futhernore, the academic writing styles are different. in science, it is streamlined but in education it is more expansive. science is mostly third person but not so in humanities.

Humanities can include arts, paintings, writing, poems etc which can occupy many words but science can be few words. Science prompts us with experiments, hypothsis and the rest but humanities are more complex and emotional.

The process of writing in humanities makes many discoveries and working out how various ideas relate to each other but in science you get your result and then write them up.

In a complete paragraph, describe your own self-concept and explain the elements you used to evaluate your answer.
Olegator [25]

Answer:

The answer is below

Explanation:

Self - Concept is a term that basically describes the individual's perception or assumption about their true self or nature. It tends to decipher the question of who an individual is.

For example, my self-concept is "I am a good teacher and loving father."

The elements I used are the following:

1. Perceived self: I believe through my observation and interactions with students and kids, "I am a good teacher and loving father."

2.   Social identity: through comments and suggestions of people I interact with. They made me believe that "I am a good teacher and loving father."

Which of the ethical traditions best describes the building of the Hetch Hetchy Reservoir as right because it benefited a large
Vera_Pavlovna [14]

Answer:

b. virtue ethics utilitarianism.

Explanation:

According to my research the Hetch Hetchy reservoir would fall under the category of "virtue ethics utilitarianism" in this case. This is because Utilitarianism places the spotlight on the  right and wrong aspects only based on the consequences of choosing a specific action or policy over other actions/policies. Since this seems to be the case when building the Hetch Hetchy Reservoir we can say that the answer is b. virtue ethics utilitarianism.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Penny gets an acting job on Friday that she attributes to her good acting. She doesn’t get the next acting job; therefore, she b
Arturiano [62]

<u>Answer:</u>

This is an example of self-serving bias.

<u>Explanation:</u>

  • In such self serving bias, people usually take credits or attribute positive things to their own.
  • On the contrary, they can easily blame others for negative events.
  • Thus, when Penny got the acting job, she made herself responsible, boasting about her own caliber.
  • However, when she failed to take the next acting work, she blamed the casting director.
  • There may be a reason that she may not had done her previous work with perfection, but self serving bias didn’t let the person evaluate that.
