Answer:
Flippase, floppase and scramblases are transport protein that helps in the movement of lipid molecules between the two leaflets of the Phospholipid bilayer of the plasma membrane.
Explanation:
Flippases
They are the trans membrane protein that helps in the transport of lipid molecules from the extracellular region to the cytoplasmic region.Flippases belong to ATP binding cassette (ABC) transporter protein family.
Floppases
They also act as lipid transporter which helps in the movement of lipid from cytoplasmic region to the extracellular region of the phospholipid bilayer.
Scramblases
These proteins help in the movement of lipid molecules between the two leaflet of the lipid bilayer of the plasma membrane.Scramblase with its catalytic activity helps in the transport of negative charged phospholipid such as phosphotidly ethanolamine from the inner leaflet to the outer leafet and viceversa.
The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
The correct option is C.
Pilli is a long protein filament which attach reproducing cells together during conjugation. This attachment allows the cells to exchange the genetic materials, that is, plasmid between them.
D. Learned behaviors do not directly affect natural selection because they are not inherited.
This is true because learned behaviors can be taught to the offspring but do not come within them the way instincts do.
In the early stages the embryos of four different species will look the same .For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth. That what makes them different.
