Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
Answer: d. None of the above
Sustainable development involves the maintenance of human community with the adequate and judicious use of natural resources so that these resources will be available for future use. Small societies can maintain stability in the long terms by following notion of sustainable development. Smaller societies have a smaller demand for resources. As, lesser the number of individuals lesser will be the demand for resources and these resources will be available for future hence, smaller societies will maintain stability. Smaller societies can be governed by internal controls more effectively than larger societies because members can control the use of resources by creating awareness among themselves and use of resources can be checked upon. Small societies rely more heavily on legislation and military forces because these can ensure that all norms of resource conservation and sustainable development are strictly followed by members of the society.
Therefore, all options are useful for maintaining stability in the society.
Answer: Amino acids; peptide
Explanation:
20 different AMINO ACIDS link together to form chains. A protein is composed of one or more of these PEPTIDE chains which are twisted and folded into a particular shape.
There exists 20 amino acids capable of forming protein in the Human body. At least two amino acids are joined together by a peptide bond to form polypeptide chains that are then held together by hydrogen bonds in twisted alpha helical structures to form proteins.
Answer:
These seven methods include: seed propagation, cutting, layering, division, grafting, budding, and tissue culture technique.
Explanation:
The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.
