Answer:
Many are supergiants.
Explanation:
A star's size and core temperature determine its brightness. The brightest stars tend to be blue or blue white. Supergiants and red giants are in the region above the main sequence of stars, so that isn't true. Red are the dimmest. Yellow stars are in the middle of that spectrum. White Dwarfs are dimmer than the Sun, red giants and blue supergiants.
ADH and aldosterone secretion are part of the body's compensation for A serious hemorrhage. Vasopressin or ADH is a hormone synthesized as a peptide prohormone in neurons in the hypothalamus and is converted to AVP. The primary role is maintaining osmolarity and thus maintaining the volume of water in the extracellular fluid, and the secondary function of ADH is raising blood pressure by constricting blood vessels. Aldosterone on the other hand is essential for sodium conservation in the kidney.
The genotypes of the embryos and endosperm nuclei embryo XX/endosperm XXX or embryo XY/endosperm XXY.
The main distinction between the embryo and endosperm is that the endosperm serves as the seed's nutritive tissue, whereas the embryo is the conceptus of fertilization. Furthermore, sperm and a binucleate central cell fuse to form an endosperm, while an egg cell and a sperm combine to form an embryo. Additionally, the endosperm is triploid while the embryo is diploid.
Angiosperm seeds contain two different types of structures: embryos and endosperm. Double fertilization is a process that causes both to happen. The two sperm nuclei in the pollen tube are also responsible for their formation in both cases.

They produce many fish with food which is positive, but the negative impact they can have is when there are too many nutrients available phytoplankton can grow out of control, in which they will produce harmful algae blooms that are toxic and can harm sea life.
