Natural resources are derived from the environment. Some of the resources are essential to survival, while others merely satisfy societal wants. Every man-made product in an economy is composed of natural resources to some degree.
There are numerous ways to classify the types of natural resources, they include the source of origin, the state of development, and the renewability of the resources.
Answer:
Hello
Explanation:
Green plants are green because they contain a pigment called chlorophyll.
Some organisms that share a common ancestor have features that have different functions, but similar structures. these are known as homologous structures.
<span>Homologous structures are organs or skeletal elements of animals which are connected via a common ancestor. These structures do not have to look exactly the same or have the same function, but they are structurally similar. The example of homologous structures is the forelimbs of vertebrates. In this example, we see that the wings of bats, the arms of primates, the front flippers of whales and the forelegs of dogs and horses are all derived from the same ancestral tetrapod structure.</span>
The acidic environment of the lysosome and the lysosomal enzymes detach the ligands from their receptors.
Receptor-mediated endocytosis is a process in which cell surface receptors are employed for transporting substances such as proteins, hormones, and metabolites from extra-cellular matrix into the cells. Receptor-mediated endocytosis usually occurs through clathrin (a type of protein)-coated pits and vesicle and it allow only the receptor-specific substances to enter the cell. Under this process, molecule binds to protein receptors after which the receptor molecule moves to clathrin coated pits and vesicle. The cell membrane then folds inwards and there is fusion of a coated vesicle. After this, the ligands are detached from their receptors.
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.
