Explanation: A scientific model can be define as the representation of the idea, process
Answer:
forward; reverse
Explanation:
Chemical equilibrium is a state where there is no tendency to change; the situation is stable.
This occurs when the reaction rate of the forward reaction is equal to the reaction rate of the reverse reaction. This is because when no rate is greater than another, the situation will remain the same.

Answer:
DNA is the genetic material of all the living organism except some viruses. The structure of DNA consists of nitrogenous base, pentose sugar and the phosphate group.
Tube 1 - The nucleotide are linked together by phosphodiester bond. As these bonds are broken, the structure of DNA contains the individual complementary nucleotide are linked together by hydrogen bonds.
Tube 2 - The bond between the sugar and the bases are broken. The DNA structure consists of the phosphate group chain only with any pairing with the base.
Tube 3 - The DNA nitrogenous bases are adenine, guanine, thymine and cytosine that are linked together by hydrogen bonds. The agents break the hydrogen bonds. Now, the DNA structure consists of the single strand only.

Answer is option C.
"This drug sometimes provides a complete cure of inflammatory bowel disease.''
Explanation:
- Crohn’s disease is a type of inflammatory bowel disease (IBD) that is caused by autoimmune or genetic factors. It affects any part of the gastrointestinal tract (from the mouth to the anus) and causes abdominal pain, fever, diarrhea, weight loss, etc.
- There is no known cure for Crohn's disease, but therapies can bring about long-term remission by greatly reducing the symptoms. For patients who have not had success with other medical therapies, Infliximab (Remicade) is used.
- Infliximab is a chimeric monoclonal antibody that binds to and neutralizes a key biologic response mediator called tumor necrosis factor-alpha (TNF-α) on the cell membrane and blocks its activity by destroying TNF-α producing cell, thus decreasing inflammation.
- For Crohn’s Disease, the FDA approved dose for adults is 5 mg/kg IV at 0, 2 and 6 weeks, then every 8 weeks.
- The common adverse reactions include urinary tract infections, upper respiratory infections and infusion-related reactions such as headache, fevers, chills, abdominal pain, diarrhea, nausea, hives, rash, shortness of breath, hypotension or hypertension, anaphylaxis, pruritus, convulsions, etc.
- Patients treated with infliximab are at increased risk for developing serious infections such as tuberculosis, fungal infections (histoplasmosis, candidiasis, blastomycosis, pneumocystosis, etc), bacterial, viral and other infections due to pathogens like Legionella and Listeria.
