Which is an arrangement of genes consisting of an operator, a promoter, and a repressor?

Answers

Answer 1
Answer: The gene sequence containing an operator, promoter and repressor is known as an operon. These genes are called as structural genes. the operon is regulated by the presence/absence of the inducer such as glucose/lactose. It may also be a constitutive operon, which works all the time.
Answer 2
Answer:

Answer:

D) Operon

A candle and a firework both can be ignited with a spark, but they release different amounts of energy as they burn. Compare and contrast the potential energy diagrams that would represent each of these burning processes.

Answers

The reactions of both candle and firework is exothermic. This means that the products have a lower potential energy than the reactants. The difference is that fireworks release more energy than the candle. In the energy curve diagrams, the fireworks will begin with a more potential energy.

Which statement is true about macromolecules?a. simple sugars are made of polysaccharides.
b. glycerol is made of fatty acids.
proteins are made of amino acids.
nucleotides are made of nucleic acids.

Answers

proteins are made of amino acids  is the true statement.

Final answer:

The correct statement about macromolecules is 'Proteins are made of amino acids'. It should be noted that in other options, the statements have a part reversed and therefore they are incorrect.

Explanation:

The correct statement about macromolecules is 'Proteins are made of amino acids'. Macromolecules are large, complex molecules that have a high molecular weight. They are mostly built from single subunits, or building blocks, called monomers. In this context, amino acids are the monomers that make up proteins which are a type of macromolecule.

To provide some clarity on the incorrect options: `Simple sugars are not made of polysaccharides` but the other way around. Polysaccharides are complex carbohydrates that are made up of simple sugar monomers. Similarly, `glycerol is not made of fatty acids`, rather, it combines with fatty acids to form lipids. Lastly, `nucleotides are not made of nucleic acids`, but nucleic acids are made of nucleotides. So, it's important to understand the relationships between these biochemistry terms to correctly understand the nature of macromolecules.

Sodas typically contain sugar, flavorings, coloring agents, and carbon dioxide dissolved in water. The best term to describe this mixture would be _____. A) an aqueous solvent
B) an aqueous solution
C) a solution
D) a solvent
E) a solute

Answers

Answer: The correct answer is aqueous solution

Explanation:

The mixture is best described as AQUEOUS SOLUTION because water is the solvent used to dissolve the various solutes (sugar, flavorings, coloring agents, and carbon dioxide). The resulting mixture is a aqueous solution known as Soda.
