Answer:
See below
Explanation:
Q1. incomplete information given
Q2. Protein will be present so <u>test tube C.</u> Beef is a rich source of protein. Hence, the Biuret test will be relevant in this case since that is specific to detecting proteins.
Q3. Orange juice has ample amount of simple sugars (such as fructose, glucose), which are monosaccharides. So option A. Benedict test is required here.
Q4. Incomplete information provided
Q5. You need a certain kind of food that is rich in protein and simultaneously lacks fats. Here, skimmed milk is relevant - fat has been removed from the milk although protein is still present.
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
The curve of Earth's surface means that solar waves hit Earth at different angles. Panama is located near the equator and receives more direct rays and more heat than Antarctica which is located near the south pole.
Answer:
pls what are the following examples always include them pls
<span>Enzymes are proteins that help in metabolic
reactions by assisting in the transfer of electrons from one molecule to
another. Hence, during metabolic functions, enzymes serve as catalysts that
lower the activation energy, allowing such reactions to occur. During
metabolism, enzymes may act on molecules called as substrates and is converting
them into a different molecule that is simply known as products.</span>
