the (drug and control) are the variable that you will change throught the conducted investigation.
Answer:
is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward
That would be. All of the above.
Answer: B) proteins in the membrane act like gates to control entrance and exit of molecules.
Explanation: Plasma membrane is composed of phospholipids bilayer in which the hydrophobic regions of the phospholipids face each other to form the core of the bilayer. Proteins are embedded in the bilayer through an interaction between the amino acid side chains and the nonpolar acyl chains of the phospholipids. The embedded membrane proteins form channels for passage of ions and other molecules. Each membrane protein is selected for one or more ions or molecules that passes through it. The membrane is said to be semipermeable because it allows the passage of some molecules and excludes the passage of others.
Carbon and Hydrogen atoms share an electron pair, forming covalent bonds special properties of carbon is ability to form double and triple bonds.
<h3>What is molecule example?</h3>
A molecule is the smallest unit of any material that is composed of one or more elements and is capable of existing independently while maintaining all of the substance's physical and chemical properties. Further atom division occurs within molecules.For instance, each atoms the particle of oxygen are represented by the letters Oh and Water vapour, together.
<h3>How a molecule is formed?</h3>
When ionic compounds come together and form bonds with one another, a molecule is created. Each atom shares an electron when a bond is formed between them. A molecule is created as a result of a covalent bond.
