A researcher asked students to teach a rat to learn a maze. Some students were told they had been given a genetically engineered

intelligent rat, whereas others were told that they had a dull rat. Although there were no actual differences among the rats, the intelligent rats learned the maze more quickly than the dull rats. Which idea discussed in your book could best explain the results of this experiment?

Answer:

Experimenter expectancy effect

Explanation:

The experimenter expectancy effect or observer expectancy effect postulates that when an experimenter is biased he can subconsciously influence the subjects in the experiment. Confirmation bias can now make the experimenter look for results that supports his bias.

This is evident in this instance where some students were given normal rats and told they were intelligent. The rats actually did better because the experimenters believed they were smarter than the other rats.

Hello. You have not added any images for the cell parts to be identified, which makes it impossible for your question to be answered. However, to help you, I will name the parts of the cell shown in the figure that is attached, as this figure also has an animal cell, this way, you will be able to relate to the image you have and answer your question. I hope it helps you.

Answer:

1. Golgi bodies

2. Cell membrane

3. Lysosomes

4. Nucleus

5. Mitochondria

6. Vacuole

7. Endoplasmic reticulum

8. Ribosome

Explantion:

Golgi bodies: they are organelles organized like flat bags, stacking one next to the others. Its main function is the secretion of substances, mainly enzymes and hormones.

Cell membrane: Its function is the protection of the cell's internal content, the delimitation of the cell in relation to the external environment and the selective transport of sub-funds to and from the cell. It is composed of poroteins and lipid molecules.

Lysosomes: They originate in the bodies of Golgie. Its main function is the degradation of harmful or irrelevant particles to the cell, but it can also act in the repair of membrane and secretion.

Nucleus: Its function is to store and protect the genetic and hereditary information of the cell. This is because it is in the nucleus where the DNA and RNA are stored, as well as the chromosomes and genes, which are essential for the maintenance of the organism.

Mitochondria: It is the most important organelle in the cellular respiration process, besides acting in glocolise, in the oxidation of fatty acids and in the formation of ATP, being one of the most important cellular structures.

Vacuolo: It does not exist in the animal cell, being found only in plant cells, but it is responsible for osmotic control, storage and digestion of substances

Endoplasmic reticulum: There are two types of endoplasmic reticulum, rough and smooth. The smooth endoplasmic reticulum has the function of producing lipids that are used in all cell membranes. The rough endoplasmic reticulum has the function of producing lipids, synthesizing proteins and initiating glycoproteins. The rough endoplasmic reticulum is identifiable by the presence of ribosomes.

Ribosomes: Its function is the synthesis of proteins, they can be inserted in the rough endoplasmic reticulum or loose inside the cell.

Answer:

bona fide occupational qualifications

Explanation:

In this scenario, the government likely was able to prevail because of bona fide occupational qualifications. This refers to a quality or an attribute that employers are allowed to consider when deciding whether or not to hire an individual candidate. Usually, this is in regard to a quality or trait, that under other circumstances, would be considered discrimination. In this case, the trait in question is Fluent Bilingual Skills, and here it is not considered discrimination because this skill is necessary and an employee without them may put lives at risk.
