Biomass might literally mean a biological mass, but it actually denotes sources that are burned to produce energy. Biomass is considered a renewable energy source. The primary one that has been used for thousands of years is wood; it is still widespread in many primitive areas and it is burned in old and new burners. Biofuels like ethanol from crops is another important source that has been on a rise. They are cheap and they are used a lot in developing countries. Finally, the burning of municipal waste is another source and many Nordic countries use it to produce energy and even some import waste to use as fuel.
Answer:
Stage 2 hypertension
Explanation:
Hypertension is a body circulatory system condition whereby the pressure of the blood vessels are raised persistently. The heart pumps blood to the different organs of the body through the blood vessels, each time it beats
The normal blood pressure in the vessel = 90/60 mmHg to 120/80 mmHg
The blood pressure of a prehypertension person or person at risk of having hypertension = 120-139/80-89 mmHg
The blood pressure at Stage 1 hypertension = 140/90-99 mmHg
The blood pressure at Stage 2 hypertension = 160/100 mmHg.
The binding of sugars are called glycosidic bonds. These bonds are covalent bonds which, by definition, surround the anomeric carbon of a monosaccharide. Contrary to popular belief, the glycosidic bond does not necessarily have to be between two monosaccharides, just think about what happens in nucleotides, for example, where ribose establishes a glycosidic bond with the nitrogen base. Of course, it can also involve two monosaccharides, as is the case with bonds in oligosaccharides or polysaccharides, but this is not required to happen.
When a glycosidic bond is established, a water molecule is released and is therefore a condensation reaction. The oxygen atom and one hydrogen are released from the anomeric carbon, while the second hydrogen atom is released from the atom to which the anomeric carbon will bind.
Glycosidic bonds are also called alpha or beta bonds. This nomenclature depends on the configuration of the anomeric carbon involved in the glycosidic bond. That is, if the anomeric carbon is in the alpha configuration, the bond is of the alpha type, if it is in the beta configuration, the bond is of the beta type.

Answer: The correct option is A (detritus).
Explanation:
The sea star also called the star fish belongs to the phylum echinodermata. They are slow moving marine animals living on the sea-shores and sea beds. They possess tube feet under their arms which enables them to move to location where they can obtain food.
During feeding, the star fish is capable of pouring digestive enzymes on the soft tissue of its prey. Once liquefied, it absorbs it into its stomach. The following are the different types of food that a star fish can feed on:
--> coral,
--> sponges,
--> clams,
--> oysters,
--> sand dollars, and mussels
They also feed on dead or decaying debris of different plants and animals. These dead or decaying debris are also called DETRITUS. A detritus is made up of leaves and other plant parts, animal remains and waste organic products that fall into water bodies from the kelp forests along the North American coastline.
