Answer: B
Explanation:
During photosynthesis CO2 reacts with water to form glucose and Oxygen.
During cellular respiration glucose and Oxygen react to produce CO2, H2O and energy. Thus the answer is B.
Answer:
For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells. This lipid and protein structure is called the virus envelope, and is derived from the host cell membranes
Explanation:
Answer:
The ATP molecule stores and creates energy. If this is not a multiple choice, then stores and increases energy is the most likely candidate.
Explanation:
ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.
The sequence of nitrogenous bases. Think of adenine guanine cytosine and thymine, and how they are ordered
Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.
