miv72 [106K]

Answer:

D). The star is getting farther away.

Explanation:

As per the question, the redshift of a star implies that 'the star is moving farther away'. It is described as the modification or increase in light's wavelength due to experiencing electromagnetic radiation from a specific object. In this effect, <u>the objects(in the space) move apart from each other as Hubble's law states the consequence of redshift i.e. leading to cause an increase in rate in their distance from the Earth.</u> Thus, the redshift of a star imply that 'the stars are moving farther away from the planet.

In the united states, which organization conducts the functions of a health ministry along with other roles?
kati45 [8]

In the united states, the Department of Health and Human Services conducts the functions of a health ministry along with other roles.

A cabinet-level executive branch agency of the U.S. federal government, the Department of Health and Human Services (HHS) was established to provide crucial human services and safeguard the health of all Americans. "Improving the health, safety, and well-being of America" is its motto. It was formerly known as the Department of Health, Education, and Welfare before the federal Department of Education was established separately in 1979.

When Reorganization Plan No. 1 of 1953 went into force on April 11, 1953, the Department of Health, Education, and Welfare (HEW) was established. The Department of Labor was established in 1913, making HEW the first new Cabinet-level department since that time. The FSA was eliminated under the Reorganization Plan, and all of its responsibilities were given to the secretary of HEW and the department, respectively.
