For fruits/vegetables, why do some sugars exist in simple forms and some sugars in complex forms?
Simple sugars are a type of carbohydrate. Carbohydrates are one of the three basic macronutrients — the other two being protein and fat.
Simple sugars are found naturally in fruits and milk, or they can be produced commercially and added to foods to sweeten, prevent spoilage, or improve structure and texture.
Monosaccharides are the simplest carbs, in that your body cannot break them down further.
This allows your body to absorb them quickly and easily, with the exception of fructose.
There are three types of monosaccharides (1Trusted Source):
Glucose: Fruits and vegetables are natural sources of glucose. It’s also commonly found in syrups, candy, honey, sports drinks, and desserts.
Fructose: The primary natural dietary source of fructose is fruit, which is why fructose is commonly referred to as fruit sugar.
Galactose: The main dietary source of galactose is lactose, the sugar in milk and milk products, such as cheese, butter, and yogurt.

If a muscle fiber were to suddenly and permanently stop producing ATP the fiber would no longer be able to actively transport calcium out of the cytoplasm (sarcoplasm) and the intracellular calcium concentration would rise. You expect what to happen
No muscle contraction will be observed.
What is the effect of calcium concentration on muscle contraction?The concentration of calcium ions in the muscle cells help in contraction and relaxation of muscles fibers.
Release of calcium ions initiate muscle contraction.
Therefore, there will be no contraction of muscle if calcium ions are not transported out from the sarcoplasm.

Answer: A
Explanation:
Lobes were the beginning of arms and legs, the correct option is A.
What are lobe-finned fish?Lobe-finned fish, unlike other fish, have a core protuberance in their fins that contains many bones and muscles.
The fins are extremely flexible and may be useful for supporting the body on land, as seen in lungfish and tetrapods.
The majority of bony fish have ray fins. These thin fins are made up of skin webs that cover flexible spines. Lobe-finned fish, on the other hand, have fins that look like stumps.
The lobe-finned fishes are the ray-finned fishes' sister group. They are distinguished by paired, fleshy pectoral and pelvic fins espoused by a single bone.
Prehistoric records clearly show that terrestrial vertebrates evolved nearly 400 million years ago from lobe-finned fishes.
Thus, the correct option is A.
