Answer:
It could mean that those two populations could be common ancestors because the spelling differences are the same
Explanation:
Forests play an important role in the economic development of a country. They provide several goods which serve as raw materials for many industries. Wood grown in forests serves as a source of energy for rural households.
Most of the world’s paper is made from wood and one rather reliable index to the degree of economic development of a country is its per capita consumption of paper. As an economy develops economically, paper is used as packaging material, in communications and in scores of other uses. No really satisfactory substitute for paper exists for many of its uses.
While it has long been recognized that forests play many roles in the economic development of a country in addition to providing wood fiber for many uses, the non-wood outputs of forests are coming increasingly to be recognized and valued everywhere in the world. Forests have watershed values especially in areas with fragile and easily eroded soils; tree cover may be highly valuable simply as protection to the watershed.
Forests are valued as a place for outdoor recreation. The kinds of forests most valuable for outdoor recreation are not always the same as the kinds most valuable for wood production and vice versa. The dense forest with trees closely spaced to take full advantage of the sunlight, moisture and fertility to grow wood, is often less attractive to the recreationist than a more open forest.
Forests are the home for many species of wildlife including mammals, reptiles and birds. Some of these forms of wildlife are clearly valuable to man. Ecologists have been much disturbed at the reduction in wildlife numbers, sometimes to the point of extinction, as tropical forests are cleared.

The question is incomplete. The complete question is - A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed and aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Brothymol blue turns from blue to yellow in the presence of CO2.
Which process would you expect the organisms in the test tubes to carry out-- cell respiration, photosynthesis or both? When would you expect each process to occur?
Answer:
Photosynthesis is the process of the formation of the food in case of plants in the presence of sunlight with the help of carbon dioxide, water and soil. The light energy is converted into the chemical energy.
The beaker is blue because plants uses carbon dioxide for their food preparation. When the beakers are kept in the dark place, instead of photosynthesis cellular respiration occur that made energy from the food for their survival.
The nitrogen cycle is impacted by humanswhenever fertilizer is applied to farmland to help crops grow. This adds nitrates to the soil. If soil erodes, the nitrates are transported and deposited in the nearest body of water. This can cause algae to overgrow in a process called eutrophication. The lake will run out of oxygen as the algae die off and bacteria begin their decomposition.Sessile organisms are greatly affected.
