Answer:
1.25
Explanation:
Index of refraction also known as refractive index determines the speed of the light in the particular material. The light can bend towards the normal or away from the normal in the particular media.
Different objects have different index of refraction. The amount of the light refracted by the media can be calculated by the help of the refractive index. The refractive index of an actual material is 1.25. The refractive index of the media depends on the density of the substance.
Thus, the correct answer is option (D).
With respect to permissions for uses and disclosures, HIPAA divides health information into three categories. The information related to "treatment, payment and health care operations" is under consent. HIPAA provides a foundation of protection of personal health records of people. Generally, it prohibits a covered entity from disclosing a protected health record unless he is granted an authorization by the patient.
Answer:
b Freezing temperatures change the quantity of ocean water, and rock made of larger grains forms the top layer.
Explanation:
Review the diagram, which shows a sedimentary sequence.
What could cause a sea-level change that would result in this sedimentary sequence?
a Melting ice caps change the quantity of ocean water, and rock made of calcium carbonate forms the top layer.
b Freezing temperatures change the quantity of ocean water, and rock made of larger grains forms the top layer.
c Rising temperatures change the density of ocean water, and rock formed in still waters appears in the upper layer.
d Tectonic activity changes the shape of the ocean basin, and rock formed in the deep sea appears in the upper layer.

B
Explanation:
<em>The correct answer would be that when sticklebacks don't use their armor, it shrinks. Then they pass lighter armor to their offspring.</em>
According to the theory of natural selection, adaptive traits that enable organisms to survive in an environment are selected by the forces of natural selection.
<u>When a particular trait is not needed for survival in an environment, the trait gradually degenerates within the population as natural selection ignores the existence of such trait. The degenerated trait is inherited by the subsequent generations of the population.</u>
The mechanism is also consistent with the law of use and disuse of organs by Jean Larmack.
The correct option is B.
