Answer:
C
Explanation:
Mutations often changes ones inner and outer features which creates genetic diversity.
I hope this helps :) Have a good rest of your day!
The gas which is released at cathode is hydrogen, H2 and the gas released at anode is oxygen, O2. ... Therefore after electrolysis the water volume of one gas collected at one electrode is double (hydrogen gas) of anode (oxygen gas).
Answer: C. The sign of the enthalpy of the reaction reverses.
Explanation: Enthalpy of a reaction is the net heat absorbed or released during a chemical reaction.It is represented by 
. It is negative for exothermic reactions in which heat is released and is positive for endothermic reactions in which heat is absorbed.
When a chemical reaction is reversed the heat of the reaction changes its sign.
The decomposition of calcium carbonate is an endothermic reaction as heat is required to break the bonds and thus energy is absorbed.
When the reaction is reversed, the reaction becomes exothermic as now bonds are getting formed and energy is released.
The 3 can only be produced in the Mediterranean biome. This biome is known to have dry and wet weather. However, the summer seasons in this biome is very dry and usually lasts longer. Hence, the vegetation is found to be drought resistant. The 3 plants mentioned are known to be naturally drought resistant, hence it is in this biome that it thrives and survives best.
Answer:
Best three management practices would be: Stream side Buffers, Cover Crops, Nutrient Management Plans.
Explanation:
- Conservation and management practices must be taught to every farmers for the deduction of chemical effect and nutrition erosion activities.
- Areas bordering stream banks that are taken out of crop production or pasture use and planted with native trees, shrubs, or grasses, helps in managing the decrease in soil fertility and an increase in chemical runoff into the waterways. This technique is called as the stream side buffers.
- To reduce runoff and erosion and enrich the soil with organic matter, cover crops must be planted. These crops soaks all the excess chemical fertilizers left on the field.
