The var multicopy gene family encodes Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) variant antigens, which, through their ability to adhere to a variety of host receptors, are thought to be important virulence factors. The predominant expression of a single cytoadherent PfEMP1 type on an infected red blood cell, and the switching between different PfEMP1 types to evade host

February 11, 2019 · youtube.com. Yo quiero - Tobe Roher ft Ariel am, G Cent y AR (Video Oficial) Answer to Question 2 (3 points) The electron configuration of the Co2+ ion is [Ar] 3d7. This ion is a) paramagnetic because it cont 1. a) Co: 1s2 2s2 2p6 3s2 3p6 4s2 3d7 b) Zn: 1s2 2s2 2p6 C; cobalt the element has the electronic configuration of [Ar] 4s2 3d7; it will lose 2 electrons from. Ar is a noble gas called as argonbecause it has stable electronic configuration.. . hence we use it .

But when cobalt loses three electrons, it loses them from BOTH the 4s and the 3d. It loses two electrons from the 3d in order to make the 3d half-filled, which has a high degree of stability, and it loses 1 electron from the 4s. The 4s and 3d sublevels are nearly identical in energy, so electrons can be removed from either sublevel. The energetically most stable structure for Sc + is therefore [Ar] 3d 1 4s 1. Making Sc: Putting the final electron in, to make a neutral scandium atom, needs the same sort of discussion. In this case, the lowest energy solution is the one where the last electron also goes into the 4s level, to give the familiar [Ar] 3d 1 4s 2 structure. 25 Mn [Ar] 3d5 4s2 [Ar] 3d5 4s1 partial filling of both 3d and 4s in Mn+ 26 Fe [Ar] 3d6 4s2 [Ar] 3d6 4s1 partial filling of both 3d and 4s in Fe+ 27 Co [Ar] 3d7 4s2 [Ar] 3d8 4s is empty for Co+ 28 Ni [Ar] 3d8 4s2 [Ar] 3d9 4s is empty for Ni+ 29 Cu [Ar] 3d10 4s1 [Ar] 3d10 1e-in 4s for Cu…4s empty for Cu+ Furthermore, most of the variant surface antigen families were overexpressed in the clinical isolates relative to 3D7, with the exception of the pfmc-2tm family, expression of which was higher in 3D7 parasites.
