Answer:
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.
When a drug binds to a receptor in the body , the receptor is activated or inactivated.
Molecules such as hormones, drugs or neurotransmitters that bind to a receptor are called ligands. The binding can be specific and reversible. A ligand may activate or inactivate the receptor; activation may increase or decrease a particular cell function. Each ligand may interact with multiple receptor subtypes.
Carbon dioxide and water are known as byproducts. Please take note that respiration and photosynthesis are basically the exact opposite of each other. Respiration takes diatomic oxygen or simply O2 from the atmosphere and changes it with carbon dioxide or CO2. On the other hand, photosynthesis takes out CO2 from the atmosphere and changes it with O2.
There are four nitrogenous bases involved.
A, T, C and G.
A:T and C:G
Answer:
D) energy from the sun, air, and water
Explanation:
Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.
For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+
. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.
Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.
