Producers are basically plants (aka living things) and consumers are basically herbivores or omivores. (Carnivores are also consumers but they don't eat plants.)
Hope this helps :D
Definitely #2 is the answer
Aorta to: arteries, capillaries, venules, veins, superior/inferior Vena Cavae, to Right atrium of the heart, through the tricuspid valve(or called the right AV valve) into the Right ventricle, then pushed through the Pulmonary valve into the Pulmonary trunk and then off into the Pulmonary-Arteries ( to the lungs), then to Pulmonary arteries( which bring blood back to the heart), then into the Left atrium through the Mitral valve into the Left Ventricle, which pushes blood through the Aortic Valve then back to the Aorta!
There is your detailed answer in order! :) yay!!
Just imagine the process in your head. Once you trace it with your mind it is easy to follow!
Good luck and I hope I helped.
A contact lens is a lens placed on the cornea of the eye.
Importance of buffers in contact lens products:
Buffers: They aim to keep the pH of the solutions at values between 6.6 and 7.8 in order to maintain the lens parameters and the effectiveness of the solutions. They are made by the combination of an acid and its sodium salt (phosphate and acetate for example). Borate and citrate buffers are used.
Importance of isotonicity in contact lens products:
The solution composed by isotonic saline solution.
Isotonia is expressed by osmolarity or cryoscopic lowering
- 0.236 to 0.446 mOsmoles / l (increases during the day)
- If the osmolarity of the mixture is different from that of the tears, it causes discomfort and irritation
• Increased tear secretion
• Increase the blink frequency
- If hypotonia, entry of water to the epithelial cells, if hypertonia: inverse
- Osmolarity restored 1 or 2 minutes after instillation
