<u>Answer:</u>
<em>
heat is released by the combustion of 
of methane</em>
<u>Explanation:</u>
The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

Answer:
Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. ... Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism.
Answer:
The correct option is<em> D. Tell the surgeon that the brother-in-law will decide after explanation of the proposed surgery is provided to him and the widow</em>
Explanation:
In the Sub- Saharan region, the customary law allows the inheritance of wife and the culture of having more than one wife is also practised in this region. According to the law, the widow will become the inherited wife of her deceased husband's brother.
In those regions, the woman are suppressed and the regions are male dominant regions. The women have to obey men's command. Hence, it will more likely be that the brother- in- law will make the decision.
