dimulka [17.4K]

Answer:

The answer to the question is

A tilted bed is said to have a _dip____, describing the angle that the bed forms with the horizontal plane--and a strike, the compass direction that lies at right angles to the tilted bed.

Explanation:

The dip of a tilted bed, describes the acute angle a tilted bed makes with the horizontal plane, by stating the numerical value of the angle from 0 to 90 degrees  as well as pointing out the orientation of the downward dipping direction in the orientation towards N, S, E, W

The strike line represents the line formed to represent the intersection of a feature of a bed  such as the bed rock surface with a horizontal plane.

The dip and the strike line of a tilted bed are always at right angles to each other on a geologic map.

To help prevent people from getting the Ebola virus, countries around the world paid to help doctors develop a new vaccine. Now
sweet-ann [11.9K]

your answer would be

B complexity

I agree that it is B but would suggest that you also consider the implications of each answer. They are all technically correct.

A is correct simply due to the fact that the longer time passes without an ebola cure, the more people can be potentially infected with it, resulting in less healthy individuals that may be able to volunteer to test potential ebola vaccines. Scientists need healthy volunteers from affected regions in order for rapid clinical trials to occur.

B is correct because of the nature of epidemics. A combination of technical, social, economic, and geographical obstacles slow the progress and dissemination of ebola vaccine information.

C is correct because finance impacts everything from finding resources used in studying ebola to distributing vaccines to affected areas. Economic imbalances or money shortages negatively impact research.

D is correct due to many social factors (more of a subjective answer). Some people think that vaccine distributors discriminate against certain ethnic groups. Others think the governments/other organizations are not effective enough at managing the situation. Still others feel that the search for a cure is not being approached in the right way. In all, there are multiple ways to oppose different aspects of ebola research.

Ultimately, B is correct because it seems to capture the meaning of A, C, and D together.

AysviL [449]

Answer:

Your vocal cords vibrate and then travel through the air to your friends ear. ... loudness is a humans perception of sound intensity, as intensity of a sound wave increases the loudness of a sound wave increases.

~+lil more info+~

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
