Answer:
<em>The correct option is cell surface markers.</em>
Explanation:
The immune cells of our body detect foreign particles and generate responses so that our body can get rid of them. The foreign particles are often termed as antigens.
The immune cells such as antibodies possess cell surface receptors which detect the foreign objects or antigens. When the cell surface receptors detect any antigen they immediately recognize that a foreign particle has invaded the body and they then identify it and start to generate response.
Answer:
Hypotonic solution
Explanation:
hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.
isotonic solution is the one you get when the solute concentration of the cell and the water are the same.
hypotonic is the one that you get when the solute concentration of the cell is higher than that of the waters.
Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.
sorry if the grammer is bad i tried my best.

Answer:
a transmembrane protein
Explanation:
A transmembrane protein spans the phospholipid bilayer one or more times. they are made of amphiphilic phospholipids: phospholipids with a hydrophilic phosphate head and a hydrophobic tail with two fatty acid chains.
Step one: Travel approximately 18 inches up the underside of the branch you are removing. Cut up about halfway through the branch.
Step two: Move to the top side of the branch. Choose a location an inch further out from your first cut. Carefully cut down until the branch breaks free.
Step three: Find the branch collar on your trunk. This is stem tissue around the base of the branch. . Make a complete cut with a 45-degree angle kicking out from the base of the tree.
