A main sequence star becomes a GIANT after it uses up the hydrogen in its core.
A giant star is a star with a large radius and luminosity that is much more greater than that of a main sequence star. A giant star is typically formed when a main sequence star deplete its hydrogen gas content. Giant stars usually correspond to the luminosity class ll and lll.
Transport of a compound across a cell membrane (down a concentration gradient) was measured at several concentrations. The presence or absence of ATP had no effect on the transport of this compound. ... Why are the lipid bilayers in cells called "selectively permeable"? They are permeable to some substances but not others.
The green tissue (that not the tissue pointed out by the arrow) in this angiosperm seed is called Endosperm
The endosperm plays the important role in the supporting embryonic growth and by the supplying nutrients, protecting the embryo and also controlling the embryos growth by the acting as the mechanical barrier and during the seed development and the germination
Endosperm is formed when the two sperm of nuclei inside the pollen grain reach to the interior of the female gametophyte (sometimes it called the embryo sac) rich in the cellular and reserves, and they are compactly arranged without the intercellular spaces..
