The relationship between a main sequence star's b-v color value and luminosity is a direct relationship.
The Hipparcos satellite measures the distances between hundreds of thousands of stars. It measures the magnitude of each stars through two filters which are, a blue filter, yielding for B magnitude (for blue) and a greenish filter, yielding a V magnitude (for visual).
The difference between the B and V magnitude of star is (B-V) color , or sometimes just "color" in short. The wavelength of light where the star is related to the star's temperature, i.e., the hotter the star the more blue it is and the cooler the star the more red it is.

Answer: b. Graves Protection and Repatriation Act.
The Native American Graves Protection and Repatriation Act is the only one of these acts that did not impact Asian Americans. The act was enacted in November 1990, and it requires institutions that receive federal funding to return Native American items to the descendants of the tribes. This includes human remains, funerary objects and other cultural items. It also establishes procedures for the inadvertent discovery of those items.
Answer:
Golgi Apparatus
Explanation:
Also called the Golgi Complex (and Golgi Apparatus or Apparatus), this organelle resembles a stack of flat sacks (cisterns). It is usually located in the central region of the cell, near the endoplasmic reticulum. This allows both organelles to perform their functions together in the synthesis and export of substances.
The Golgiense Complex is a membranous organelle (has a simple membrane that delimits its volume) composed of stacked cisterns associated with the Smooth and Rough Endoplasmic Reticulum.
It is responsible for sending synthesized substances inside the cell to the extracellular area, in a process known as Cell Secretion (exocytosis).
It also performs the function of distributing, packaging and modifying proteins. An example of this is the addition of sugars, a process called glycosylation.
The Golgiense Complex also forms the sperm acrosome, the lysosomes, and also aids in the maintenance of the plasma membrane and cell wall.
