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)
Answer:
FALSE!!! Thermal energy can be transformed to heat.
Explanation:
<span>
An Endothermic Reaction occurs when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products
An Exothermic reaction is one that releases energy in the form of heat or light.
</span>Exothermic Reactions: Rust and Setting of Cement
Endothermic Reactions: Photosynthesis and evaporation.
One example of an endothermic reaction is Ice packs. The packs that deliver instant cooling when a seal inside is broken. It works by having water and ammonium nitrate in separate compartments and then when you break the seal between them they mix. The reaction is endothermic so it takes in heat from the surroundings so the pack become cold.
I hoped this helped you!
Answer:
CO2 soild is "Dry Ice".
Explanation:
if the pressure of liquid CO2 is suddenly released is proportion of the liquid will change to the soild state( become dry ice ) and the remainder will revert in gas..
