The answer would be B. :)
Answer:
During the day, plants produce (oxygen) by splitting water molecules in the light-dependent reactions of photosynthesis. At the same time, plants use cellular respiration to produce some of the (carbon dioxide) needed by the light-independent reactions to make sugars. During the night, plants produce (carbon dioxide, but not oxygen) because (only cellular respiration) takes place.
Explanation:
I will try to explain you, why is this the correct answer. During the night, there is only cellular respiration. Let me give you equation to understand the concept better. The equation of cellular respiration is: C₆H₁₂O₆ + 6O₂ + 6H₂O -> 6CO₂ + 12H₂O + ATP (energy) .. During the cellular respiration, the organism is making carbon dioxide, water and energy from glucose and oxygen. The plants are using oxygen during the night and making carbon dioxide.
I hope I helped you. I will be really happy, If you mark my question as brainliest.
The type of lipid formed from rings of carbon atoms which regulate sexual function, blood glucose levels and are an important component in <u>cell membranes</u> are known as Steroids.
Steroids- A steroid is an organic molecule having four rings organized in a certain chemical configuration that is physiologically active. The two main biological roles of steroids are as signaling molecules and as critical elements of cell membranes that affect membrane fluidity.
Cell Membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The movement of materials into and out of the cell is controlled by the cell membrane.

The most abundant element in the atmosphere can also be is nitrogen since nitrogen gas accounts for about 78% of the atmospheric gases. Beans and whey protein are, of course, high in protein, and a fundamental component of proteins at the molecular level is a nitrogen-containing group called an amine group.
Active transport (exocytosis, endocytosis, pumps, etc.)
