Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:
A + B + X --> C
A + B + Y --> C
A + B + Z --> C
The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.
I hope it helps, Regards.
Answer:
Prepare three test tubes containing reactant A.
Prepare three test tubes containing reactant B.
Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns.
Time the reaction until bubbling stops.
The unknown that causes the reaction to occur the quickest is the catalyst.

Answer:
Option A, most closely related to mammals
Explanation:
Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.
All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other
Hence, option A is correct
a. True
b. False
b. Makes mRNA from DNA, binds to DNA, detaches
c. Binds to DNA, detaches, makes mRNA from DNA
d. Binds to DNA, makes mRNA from DNA, detaches
Answer:
D. Binds to DNA, makes mRNA from DNA, detaches.

Explanation:
just took the quiz
a. True
b. False
Answer:
a. True
Explanation:
b) proteins shapes determines which amino acids are made
c) proteins shape determines the shape DNA
d) proteins shape determines how much energy is stored in the protein molecule
The importance of a proteins shape and structure determine the protein function.
The Primary structure of proteins is the linear ordering of amino acids, bound by Covalent,peptide bonds to form primary structure.
Secondary structure refers to local folded structures formed due to hydrogen bonding between the amine and carboxyl group of the peptide link of polypeptide chain.
These structure present in two forms like α – helix form which is a polypeptide chain forms hydrogen bonds by twisting into a right-handed screw with the -NH group of each amino acid residue.
The β – pleated sheet structures are the peptide chains are stretched out ,laid side by side together by intermolecular hydrogen bonds. The structure resembles the pleated folds of drapery.
Tertiary Structure of Protein refers to folding of the secondary structure by H-bonds, electrostatic forces, disulphide linkages, and Vander Waals forces stabilize this structure. Quaternary Structure of Protein refers to spatial arrangement of various tertiary structures.

Answer:
Proteins catalyze chemical reactions by bringing them together in the right orientation and helping them react together. If they have the wrong shape they cannot do this. This is because with the wrong shape, the pieces will not fit together properly
