I think they contain covalent bonds, between the carbon atoms and also between the carbon atoms and hydrogen atoms. Polymers consist of chain-like molecules that are in turn, made up of numerous smaller, repeating units called monomers.
Answer;
-They all provide water
Explanation;
In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.
In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.
-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.
Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.
The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"
This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
It’s phenotype is brown fur.
Answer:
The mutation is on chromosome/karyotype 8.
