During a dehydration reaction, two monomer molecules are covalently bonded to each other, with the loss of a water molecule. In this reaction, each monomer contributes part of the water molecule that is released during the reaction. This reaction is repeated as monomers are added to the chain one by one, making a polymer.
Answer:
1) IRIS
2) LENS
3) RETINA
4) Fovea Centralis
Note: Answers 1 - 4 follows question pattern
Explanation:
The PUPIL is the hole in the MIDDLE of the IRIS of the eye, through which light passes to be focused on the RETINA.
The IRIS is the contractile membrane perforated by the pupil, which adjusts to control the amount of light reaching the retina, and which forms the colored portion of the eye
ACCOMMODATION is the change in the adjustment of the eye lens to help focus light ray.
RETINA helps to receive light rays that the lens has focused. It contains two cells: rods and cones
Fovea Centralis is at the center of the retina responsible for sharp and accurate vision, also it is where cones cells cluster.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
