Answer:
True
Explanation:
Halogens belongs to the seventh group on the periodic table. This group contains the most reactive set of elements that we have. They require just an electron to achieve a noble and stable electronic configuration.
When halogens mostly in form of ChloroFluoroCarbons(CFCs) reaches the atmoshpere, ultraviolet rays release chlorine atoms which easily breaks away an oxygen atom from ozone. Ozone thereby turns into an oxygen gas with two oxygen atoms instead of three. This reaction depletes the ozone layer.
A one-use item is disposable, because it is disposed after its use.
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
The answer is;
- Biotic – planktons
- Abiotic - temperatures
A biotic factor that affects viral activity is planktons and bacteria in the sea. Viruses insect bacteria, planktons and use their machinery to replicate themselves. Viruses, therefore, lyse and kill many bacteria in the seas and make carbon available in the oceans- hence drive the carbon cycle.
Temperature is an abiotic factor in the sea that affects viral activity. Higher temperatures or too cold waters will reduce viral activity in the oceans and seas.
