The answer is transmission electron microscope.

A compound light microscope is not useful in observing structures inside the cells because they have not as high resolution as a scanning electron microscope and a transmission electron microscope. The latter two give much higher resolution, but the scanning electron microscope allows the study of the surface of the objects. So, it would not be possible to look at the internal structures of the cell on the scanning electron microscope. On the other hand, the t<span>ransmission electron microscope allows studying a very thin cross-section of the cell. It is best for looking at internal structures of the cell, including organelles.</span>

The following ORs are reported for several hypothetical examples. Give your interpretation of the results, assuming all results
musickatia [10]

Answer:

a) Protective effect on the health or incidence of disease (low-fat diet and colon cancer)

b) No association between exposure and incidence of disease for health (aerobic exercise and dental caries)

c) Positive association between the incidence of disease and the exposure (exposure to side-stream cigarette smoke and lung cancer)

d) Positive association between the incidence of disease and the exposure (infectious disease of the pelvis and ectopic (tubal) pregnancy).

Explanation:

The interpretation of OR can measure the association between the frequency of exposure and health in a sample that is considered statistically significant. When the OR is equal to 1, it means that there is no association between exposure and an incidence of health disease. When the OR is equal to 0.5, it means that the exposure has a protective effect on the incidence of the disease on health. And finally, when the OR is above to 1, it means that there is a positive association between the incidence of the disease and the exposure.

a) OR = +0.6. Since this value is less than 1 but greater than 0.5, it means that the exposure has a protective effect on the health or incidence of the disease.

b) OR = +1.0. As in this case, the OR value is equal to 1, meaning that there is no association between exposure and the incidence of disease for health.

c) OR = +1.3. As in this case the value is greater than 1, it means that there is a positive association between the incidence of the disease and the exposure.

d) OR = +3.0. There is a positive association between the incidence of the disease and the exposure. The OR 3 value means that the incidence of the disease and the health result will be three higher in people who are exposed.

Answer:

According to the information on the map, the temperature pattern showing the isotherms is temperatures increase from the center of the country toward the Southwest (option D).

Isotherms are lines drawn on a map to show areas that -according to their geographical characteristics- have the same temperature level. with the same temperature levels.

On the map presented, an increase in temperature from north to south can be clearly seen, with the<u> temperature in the centre (20°) showing a pattern of increase towards the southwest (30, 40 and 50°)</u>.
