Answer:
A
Explanation:
Remember the number of valence electrons represent the group number. As shown in figure, there is only one electron in the valence shell. Therefore, this element belongs to group 1 elements also called as Alkali metals.
Furthermore, the number of electrons in a neutral atom equals number of protons. Hence, there are 11 protons in this element.
Also, number of protons equal atomic number therefore, the atomic number of this element is 11. And, by checking periodic table, the element having atomic number 11 is Sodium (Na).
An emerald can be described as a precious gemstone that is commonly green. However, emeralds can be other colors. Emerald commonly describes a color, such as emerald green eyes.
I think it is B. Earths magnetic feild
But i'm not sure.
Answer:
B). The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.
C) The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.
E) The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar
Explanation:
A liposome is simply a tiny bubble also referred to as vesicle that is gotten from the same material as the one a cell membrane is made from. It should be noted that liposomes can be filled with drugs, and then used in the delivery of drugs for diseases such as cancer etc.
Phospholipids afford fluidity, permeability and stability to neural membranes. They're also vital for proper functioning of the receptors, integral membrane proteins, and the ion channels.
The characteristics of phospholipids that enable liposomes to form in water are:
• The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.
• The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.
• The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar
