The options in the question are shown in the image attached to this answer
Answer:
A
Explanation:
A peptide bond is formed between a carboxylic acid and an amine group. These two functional groups must be in the correct orientation before they can react to form the peptide bond.
If we study the images closely, only the amine group and carboxylic acid in option A are correctly positioned for reaction to take place leading to the formation of a third peptide bond.
Amino acids connect by peptidic bonds to form the linear structuresof proteins. In the peptidic bond, the amino group joins the carboxylic group, and a water molecule is released. Among the options, A is the correct one.
-------------------------------------------------------
Amino acids are organic molecules.
They are composed of a central carbon, one hydrogen atom, one carboxyl group (COOH), one amine group (NH₂), and one R group. The composition of the R group is what makes them different from each other.
Proteins are amino acid polymers linearly arranged and connected by peptidic bonds.
The number of amino acids composing the chain and their order determines the primary structure of the protein.
The protein is synthesized from the amino terminus to the carboxy terminus.
The peptidic bond is the union of two amino acids by their carboxyl and amine groups.
When they get together, a water molecule is released, producing a covalent bond ⇒CO-NH.
Peptidic bonds only form linear structures, with no ramifications, known as peptides.
In this way, every peptide has a free carboxylic group in one extreme and a free amine group in the other extreme.
Among the given options, the correct position of the dipeptide and the amino acid to form a tripeptide is option A.

Answer:
True
Explanation:
Bloodflowisaffectedbybothbloodpressureandvesselresistance.
Blood flow is indeed affected by both blood pressure and vessel resistance. While blood pressure is the force exerted by blood on the vessel walls, vessel resistance is the opposition to flow that blood encounters in vessels. Both factors significantly impact blood flow.
The statement 'Blood flow is affected by both blood pressure and vessel resistance' is true. Blood pressure is the force exerted by the blood against the walls of the blood vessels. The higher your blood pressure, the harder your heart has to work to pump blood. On the other hand, vessel resistance refers to the opposition to flow that the blood encounters in vessels away from the heart. Factors that impact vessel resistance include vessel diameter and blood viscosity. Thus, both blood pressure and vessel resistance play critical roles in affecting blood flow.
