q1. all of these
q2 false
q3 can be in liquid, solid or gas forms
q4 idk
q5 They usually remain radioactive for less than 100 years.
q6 idk
q7 TRUE
educated guess and i remember some things from chem. Hope its all good
I think it can be c. selecting teams based in height
Answer:
Explanation:
We classify the behaviours of electrolytes based on their electrolytic conduction. This is what makes them breaks down when in aqueous solutions with water.
A strong electrolyte is one that ionize completely when in aqueous solutions. Their ionization can be shown below using appropriate chemical notation:
An example of a strong electrolyte is NaCl:
NaCl
→ Na⁺
+ Cl⁻
Such reactions have a single forward arrow. Since they ionize complete, they have a large amoung of ions present in their aqueous form and would readily conduct.
A weak electrolyte is made up of compounds that ionize partially or slightly in their aqueous solution. The amount of ions produced per mole of compounds is relatively small compared to those of strong electrolytes. Examples ae organic acids, weak bases, and water. This ionization is shown below for methanoic acid:
HCOOH
⇄ HCOO⁻
+ H⁺
This sort of reaction is an equilibrium reaction. This is why we have the double arrow.
None electrolytes do not ionize at all in aqueous solutions and they produce no ions.
Answer:
The correct option for question 1 would be:
a bilayer containing lipids with hydrophilic head groups pointing inward and hydrophobic tail groups facing the solvent (extracellular fluid and cytosol).
The correct option for question number two would be: proteins.
Explanation:
The membranes present phospholipids that act as selective barriers between the intracellular and extracellular space, allowing an internal balance in relation to the external one.
Its conformation is mostly phospholipids, fatty acids, proteins (from transmembrane to intermembrane or external)
