It is fun to repeat an experiment over and over.

Answers

Answer:

Completing more than one trial during the use of a scientific method experiment shows consistency in test results which demonstrates that they are replicable.

Explanation:

In the scientific method, the phase of experimentation is carried out both to check if a hypothesis is correct and to refute it. In this sense, the realization of several trials during the experimentation ensures that reliable results are obtained.

The repetition of trials during the experimental phase not only gives greater strength to the final conclusion, but can demonstrate that the experience can be carried out repeatedly obtaining the same result.

The other options given are not correct because:

During the experimental phase there is no opportunity to practice procedures.The repetition of trials is done to obtain consistent data and not to repeat until the desired result is obtained.Experimentation should be serious and not done for fun.

How does the brain create visual hallucinations in schizophrenia?

Answers

Answer:

Hallucinations are perceptions in the absence of an external stimulus and are accompanied by a compelling sense of their reality. They are a diagnostic feature of schizophrenia, occurring in an estimated 60%–70% of people with this disorder, with auditory hallucinations being the most common. However, hallucinations are not only associated with illness but can also occur in healthy individuals. For example, data from 6 community survey studies in various countries indicate that 7%–30% of children and adolescents report experiencing hallucinations.1 In the context of grief after the death of a spouse, one-third to one-half of bereaved spouses report hallucinations of the deceased.2,3 Transcultural influences may also affect the distinction between reality and imagination as well as the normalcy of visualizing images and ideas.4 In healthy people, pseudohallucinations can even be generated at will by mild sensory deprivation; for example, vivid dreamlike visual imagery can be induced in some individuals by placing 2 halves of a ping pong ball over the eyes and playing a recording of the sounds of a waterfall for several minutes.5 The neurobiological basis of hallucinations has most frequently been investigated in patients with schizophrenia, although studies examining hallucinatory phenomena in healthy individuals may also be informative. It should be noted, however, that it is unknown at present whether hallucinations are generated by similar mechanisms in patients and in healthy people.

Which of the following sports originated to improve the physical fitness for bedridden soldiers from World War 1?
a. yoga
b. pilates
c. martial arts
d. running​

Answers

Answer:

b. pilates

Explanation:

"Pilates" is a form of exercise developed by Joseph Pilates, a German fitness instructor in the 1880s to 1900s. Though he grew up as a sickly kid, he later became a body builder and developed concern for people's poor health brought about by the relatively easier lifestyle of the modern world–which was coupled with a bad posture.

Later on, he developed the concept of pilates to teach and encourage people to become healthier. During World War 1, he used the physical fitness system to rehabilitate people who went to war. Most of these people were bedridden soldiers (including the prisoners of war). This aided them to gradually get their mobility back.

is dietary iron consumption especially important for reproductive-age females ​

Answers

Answer:

They lose blood every month during menstruation.

Explanation:

Females of a reproductive age undergo menstruation, during which the uterine lining sheds every month, causing bleeding. This means their iron needs are higher than their male counterparts.

The lost blood needs to be replaced, which requires iron. Iron is an important part of hemoglobin, an important protein in red blood cells that helps in the transport of oxygen around the body.

Women who lose a lot of blood during their period are at higher risk of iron deficiency and may need to take iron supplements.
