Yes, the story surprised me very much. However, I don’t think these similarities are something the twins inherited, I think they are coincidences. You can’t inherit the same wife or other similarity that are not decided by genes.

Colt1911 [192]

Answer:

Light-dependent reaction of the photosynthesis takes place in the thyllakoid membrane of the chloroplast. It converts solar energy into the chemical energy (ATP and NADPH) which is then utilized in the light-independent reaction to fix carbon into glucose or food.

The correct order of events that take place during light-dependent reaction would be:

Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.

                                                         ↓

Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space.

                                                         ↓

The concentration of hydrogen ions in the thylakoid space increases.

                                                         ↓

Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.

                                                         ↓

ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.

Grace [21]

Answer:

he Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to  Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.

Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.  

The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.

This can get you started, I didn't want to make it too easy on you! :) It has I believe 126 words, I hope you find it useful!
