Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules
timurjin [86]

Answer and Explanation:

a. form the antigen-binding site ⇒ both chains

The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.

b. contain multiple variable domains ⇒ none

Both chains - light and heavy - contain <u>only one</u> variable domain (VL and VH).  

c. are found in the Fab fragment ⇒ both chains

The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.  

d. are found in the FC fragment ⇒ heavy chains

The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.  

e. contain only one constant domain ⇒ light chains

Each light chain contains one variable domain (VL) and one constant domain (CL).  

f. contain multiple constant domains ⇒ heavy chains

Each heavy chain contains three constant domains: CH¹, CH² and CH³.  

g. contain only one variable domain ⇒ both chains

Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.

A living cell is placed into a hypotonic solution . Compare the solute and solvent concentration inside the cell with the concen
frosja888 [35]
<h2>Answer:</h2>

The living cell concentration is hypertonic than outer solution hence the concentration of solutes will be higher than the solvent.

<h3>Explanation:</h3>
  • In the question description it is mentioned that cell is present in the hypotonic solution than cell environment will be hypertonic.
  • In the cell the solute will present in the concentrated form.
  • Hence the water will move from the outer environment into sell through the osmosis.
  • Osmosis is the movement of water from higher concentration to low concentration through semi permeable membrane.
  • Hence the cell will swell due to water collection in cell.

URGENT!!!!!!!!!!!!Which are examples of convection currents? Check all that apply.
Aloiza [94]
I believe a pot of water that is being heated by a electric burner. This is because the warmer water moves to the top and the cooler water moves down to the bottom of the pot. This causes a circular motion. The next example of convection heat is a hot air ballon rising and falling in the atmosphere. A radiator is also because the hot air is drawn out the top and the cooler air is drawn to the bottom.
