Afforesting is a positive effort in curbing the over use and destruction of natural forests

Biology

Eduardwww [97]3 years ago
3 0

Answer:

Explanation:

Afforestation simply refers to a campaign in favor of tree planting, against tree cutting in reserves or vegetation and the overall protection of the Forest reserve. Afforestation in the direct opposite of deforestation which is act of cutting down and destruction of forest trees. Trees are important part of our natural environment which plays economic, biological and chemical roles in the lives of the masses. Most notably, forest trees acts as carbon sink which in turn reduces depletion of the ozone layer. Even though their are economic derivatives in the cutting selling of forest planks for various purposes, tree planting culture must be legislated in other to avoid excessive use of forest reserves.

Why does limestone react to acid rain, but sandstone does not?
motikmotik

Answer:

Sandstone does not react with Hydrochloric acid. The acid soaks into the rock because the rock is porous, filled with tiny holes. It is made up of tiny grains of sand cemented together by intense pressure.

Rus_ich [418]

Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.

Explanation:

Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. <u>Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them.</u> When the fluid exerts outward pressure on the cell wall it is called turgor pressure.  Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.

So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.

Thereby, the turgor of a living cell is influenced by three primary factors:

  • An adequate supply of water.
  • The formation of osmotically substances.
  • A semi-permeable membrane.

Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.

The transformation of ammonia (NH3) into nitrate (NO3) is mostly performed by certain bacteria. This process is known as…
Orlov [11]

Answer:

b. Nitrification

Explanation:

Nitrifying bacteria are present in the soil that help in the oxidation process of ammonia that liberates the nitrite (NO2-) and nitrate (NO3-) compounds. These resulting compounds are captured by plants and this process is called nitrification. In the nitrification stage there are two chemical processes. That are:

• Nitrous: is the oxidation of ammonia (NH3) that results in the nitrite chemical compound (NO2-).

• Nitration: It is the oxidation of ammonia (NH3) that results in nitrate (NO3-).
