Answer:
The oblique illumination is
used by the microscopists to resolve N. Spencrii in the Dark Field Condensers.
Explanation:
It was found that the use of oblique light was required to resolve the striae. Oblique illumination was the first step toward dark field microscopy. In dark field, light
seems to radiate from the specimen while all the rest of the field is black. Resolution is as good as that in bright field while contrast is enhanced.
In dark field microscopy, no
direct light from the condenser enters the objective lens. Only light
that is reflected, refracted or diffracted by the specimen enters the objective. The dark field condenser produces a circle of light. The
light is at an extremely oblique angle to the surface of the slide. This
oblique light comes to a focus on the specimen. It then diverges so
strongly that no direct light enters the objective. This type
of illumination is a hollow cone of light.
Answer:
Today, there is a great loss of healthy habits both in the adult population and in school children. On many occasions, schoolchildren are provided with the food they want or they do not take the necessary time to teach them to have a good diet and, on other occasions because parents, educators or school leaders do not have good eating habits.
It should be noted that children or school children learn family eating habits, that is, if adults do not eat vegetables, obviously children will not take it either.
This situation of poor food choices does not lead to more or less severe malnutrition. Usually the clinical problem that appears is the development of deficiency states, especially in micronutrients. The best example that a child can get is watching their fmiliares eat healthy since they are living in a stage that everything they see mimic it, so for them to create healthy eating habits, they should change the way they eat at home Similarly.
Hello. This question is incomplete. The full question is:
"A psychology professor wants to know whether verbal ability is related to memory quality in current first-year students at her small college. Participants in the study (first-year students at her college) complete an online memory task. The students are first shown a list of 60 words. Next they are shown a list that includes five new words that are conceptually similar to words on the original list. Then they are asked to identify the words on the second list that appeared on the original list. She uses the percentage of new but conceptually similar words that were mistakenly thought to be on the original list as her measure of memory quality. She also asks the students to report several characteristics such as their age, gender, and verbal SAT score.
Which of the following are variables in the study? Check all that apply. The students' verbal SAT scores The students' percentage of words that were correctly recognized on the original list The number of students participating in the survey."
Answer:
The student's verbal SAT scores
The student's percentage of words that were correctly recongnized on the original list.
The number of students participating in the survey.
Explanation:
Within all scientific research, variables (dependent and independent) can be verified. These variables correspond to the number of factors that can take on value within the experiment and dissolve results for the research to be completed.
Accordingly, we can see that the variables of the experiment shown above are:
- The student's verbal score in the SAT: presents a value and shows the difference between the students allowing a comparison to be made.
- The percentage of words of the student that were correctly refilled in the original list: Also assumes a value and shows a result that is directly related to the veracity of the hypothesis of the study:
- The number of students who participated in the study: It also assumes a value and will allow calculations and graphs to be made to show the results.
Answer:
falling on his head
Explanation:
it depends on how hard he hit it but yea
The answer for that question is: increases ; increases
The positive behavior could increase the likelihood of the behavior by giving some sort of reward to someone if that person is doing a certain behavior.
The negative reinforcement could increase the likelihood of the behaviour by punishing that person if that person is NOT doing that certain behavior.
so in the end both reinforcements will increase the likelihood
