With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.
Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.
More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.
Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.
The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.
Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
So I would say seaweed belongs in the hydrosphere.
I hope it helps.
Answer:
The correct answer is NAD+
Explanation:
Glycolysis is the process that occurs in almost all the cells. It occurs in the cytoplasm in both prokaryotes and eukaryotes. In glycolysis partial oxidation of glucose takes place step wise and one glucose molecule gets convert into 2 pyruvate.
The molecule that helps in the partial oxidation of glucose is NAD+. NAD+ is an electron carrier that harvest energy in a series of gradual step from glucose in the form of electrons and gets reduced into NADH.
Then this NADH is used to feed electrons in the ETC during oxidative phosphorylation to make ATP and get regenerated into NAD+. So the correct answer is NAD+.
