Epidermal tissue system is the outermost covering of plants. It consists of epidermis, stomata and epidermal outgrowths. Epidermis is generally composed of single layer of parenchymatous cells compactly arranged without intercellular spaces. But it is interrupted by stomata. In leaves some specialized cells which surround the stomata are called the guard cells.
Answer:
True
Explanation:
Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.
Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.
<u>Some</u> of the principal human activities responsible for biodiversity loss are
- the uncontrolled use of unrenewable resources,
- overexploitation of renewable resources;
- land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;
- the unplanned advance of cities, and opening of new roads to connect those cities.
All of them involving
- deforestation and fragmentation of natural landscapes;
- water, air, and soil pollution,
- species loss, and reduction of biodiversity.
With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.
Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking
- The respect for nature,
- People´s education at different levels to care and protect wildlife,
- Interest in keeping ancestral knowledge,
- Planning and previous environmental impact studies,
- Policies to control human activities,
- Caring involved government.
If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.
<span>The answer is b. have a change in dipole moment
When a molecule absorbs an infrared ray, its energy will increase. The energy will increase the rotational movement or the molecule. If the energy increases further, it will become the vibrational movement. Dipole moment will be increased if the vibrational movement is increased.</span>
The types are Blackwater, Graywater and Yellow water.
You can find two types of wastewater: household sewage and wastewater
Rough ER - protein synthesis, transport of proteins throughout the cell
Smooth ER - lipid synthesis and cell detoxification
