Which of the following activities will help make rural societies more sustainable? A. Design energy efficient forms of transport
denpristay [2]

Answer:

The correct answer would be Option C, Multipurpose Trees.

Explanation:

With the advancement in industries and other areas of technology, the rural areas have become so much polluted. So the sustainability of the rural areas is doubtful. The air in the rural areas have become polluted and needs measures to prevent it from harmful consequences of the industrial advancements. Along with industries, the air pollution is also added through vehicles discharge, waste disposal, etc also contribute towards the non sustainability of the rural areas. So to overcome all these problems, the best solution is to grow the multipurpose trees in the rural areas as much as possible to increase the sustainability of these areas. With the plantation of trees, the problem of pollution will be controlled and thus make these areas sustainable.

Does photosynthesis and cellular respiration need enzymes? Why?
leva [86]

Photosynthesis is the process by which plants use the sunlight as a form of energy by converting carbon dioxide to make organic compounds that are necessary for growth.

In the first two stages of photosynthesis, the enzymes of the light-dependent reactions are activated by light and oxidation occurs, yielding oxygen gas and hydrogen ions. The hydrogen ions are used in the electron transport chain and are passed through the thylakoid. The electron transport chain results in the catalyzed reaction of adenosine diphosphate, or ADP, to adenosine triphosphate, or ATP, which is a source of chemical energy.

Later on in the Calvin cycle, the enzymes are important for the production of a three-carbon sugar, then a six-carbon sugar. There are three phases of the cycle that are powered by ATP and nicotinamide adenine dinucleotide phosphate, or NADPH. Being that the Calvin cycle is a metabolic pathway, the carbon compounds produced in the cycle are an important energy source that are used to make organic compounds used by the autotroph.

The concentration of solute is less on one sides of the membrane causing water to move into the cell causing the cell to swell.
andrezito [222]

When a cell is immersed in a hypotonic solution, the volume of the cell will rise as it will cause will be a net inflow of water inside the cell. If the concentration of solutes outside the cell is lower as compared to inside the cell and when the solutes are not able to cross the membrane, then the solution is called hypotonic to the given cell.

The ability of an extracellular solution to induce water to osmotically enter or depart a cell is known as tonicity.

Three terms—hypertonic, hypotonic, and isotonic—are employed in order to evaluate if a solution would cause water to move into or out of a cell:

  • If a cell is immersed in a hypertonic solution, it will lose volume because there will be a net flow of water out of the cell.
  • A cell will shrink if it is submerged in a hypertonic solution because water will escape the cell.
  • Since there is no net water movement in an isotonic environment, the cell's size remains constant.
  • A cell will absorb water and swell when it is exposed to a hypotonic environment.

How do the methods of scientists lead to knowledge?
motikmotik
The process of the scientific method involves making conjectures (hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture, based on knowledge obtained while seeking answers to the question.
