What is a carbohydrate? List three facts about glucose. Assume that you are trying to identify an unknown organic molecule. It c

ontains only carbon, hydrogen, and oxygen and is found in the cell walls of a newly discovered plant species. What type of organic compound is it? Why? Compare and contrast the structures and functions of simple sugars and complex carbohydrates.

Answer:

This is a question with multiple parts in it, so here goes the answers and the short explanations, because it is a long one.

1. What is a carbohydrate: Carbohydrates are organic compounds, that can be found as sugar or starch and that are high providers of energy for living organisms. Their chemical composition is basically a combination of carbon, hydrogen and oxygen atoms, in different configurations, depending on the complexity of the compoung and the molecules that form it.

2. List three facts about glucose: a) Glucose is the most basic molecular unit in carbohydrates and it is the preferred energy provider for certain organs in the human body, like the brain. b) Glucose is also a product of photosynthetic pathways in plants, as glucose also is the preferred energy provider. c) Glucose is a simple monosaccharide and is commonly known as a simple sugar.

3. Assume that you are trying to identify an unknown organic molecule. It contains only carbon, hydrogen, and oxygen... What type of organic compound is it? Why?: Basically we would be talking about a carbohydrate here and the reason is because of the chemical composition given to us by the question itself. A basic composition of carbon, hydrogen and oxygen, with nothing else added, is the very chemical definition of carbohydrate compounds.

4. Compare and contrast the structures and functions of simple sugars and complex carbohydrates. The essential units of carbohydrates (starch and sugar) are monosaccharides, meaning, their carbon, hydrogen and oxygen structure is a pretty simple one. These monosaccharides like glucose, or fructose, are the most basic energetic molecules and are the ones used for energy production by cells. All other types of sugars will first be broken down into monosaccharides to be used as fuel by cells. Disaccharides are a combination of monosaccharides and their advantage is that their breakdown produces even more energy than monosaccharides. Also, more monosaccharide numbers can be taken out of the consumption of foods made up of disaccharides. Polysaccharides, or complex carbohydrates are a combination of mono and disaccharides, as well as other components, and we usually know them as the carbohydrates. These will yield most of the energetic material needed by cells to work in the absence of other fuels  and when in excess, parts of their molecules will be stored by the body as glycogen and also as fat.

The image below shows a convergent plate boundary.
JulsSmile [24]

Answer:

the answer is volcanoes

Explanation:

The oceanic crust collides with the continental crust to form a convergent boundary. At the convergent boundary, the denser oceanic crust sinks under the lighter continental crust. The rocks of the oceanic crust reach very high temperatures of about 12,000°C, which is enough to melt the rocks. These molten rocks travel upward through cracks and crevices in the continental crust. They then erupt on the surface as volcanoes. Therefore, the feature expected to form at point X as the result of converging plates would be volcanoes.

When too walk your dog you are using energy from the sunlight to power this activity. explain
GrogVix [38]
<h2>When too walk your dog you are using energy from the sunlight to power this activity</h2>

Explanation:

The ultimate source of energy in the ecosystem is the sun. When we take our dog for a walk, we are utilizing energy stored in our body that we obtained food. We must have obtained that from either plants or animals. The animal in turn must have obtained its food from plant. Plants are the organisms in the food chain who can convert the energy from the sun into the chemical energy. So, we can say that when we walk our dog we use energy from the sunlight to power this activity.

When a red blood cell is placed in a hypertonic solution, which will occur?
Sergeu [11.5K]
If a red blood cell is placed in a hypertonic solution, the cell would shrink.

Hypertonic solution means that the solution has a lower water potential than the other side (which is the cell's cytoplasm in this case), and by that, water molecules would have a tendency to flow from a region of higher water potential to a region of lower water potential. This movement of water molecules is called osmosis. But note that a semi-permeable membrane (a membrane which can decide what substances can go in and out, the cell membrane is an example) has to be present in osmosis, or else the movement may be regarded as diffusion.

As the water molecules flowed away from the red blood cell cytoplasm, the cell loss so much water that the membrane has nothing much to hold and thus the cell shrinks.

What is happenining to the forest of Madagascar and what is the outcome?
romanna [79]

Environmental Threats have come upon Madagascar lately like, Deforestation and habitat destruction. Agricultural fires. Erosion and soil degradation. Overexploitation of living resources including hunting and over-collection of species from the wild. Its a very sad thing :(
