Answer:
Explanation:
Peat is the least carbon efficient fuel source when compared to other fossil fuels such as oil, natural gas or coal, and its combustion can emit over 90% of total CO2 emissions of the full peat energy chain.
Burning wood pellets releases as much or even more carbon dioxide per unit of energy as burning coal, so in order for burning pellets to be carbon-neutral the carbon emitted into the atmosphere has to be recaptured in regenerated forests
Biofuels may be carbon-neutral because the plants that are used to make biofuels (such as corn and sugarcane for ethanol and soy beans and oil palm trees for biodiesel) absorb CO2 as they grow and may offset the CO2 emissions when biofuels are produced and burned.
Growing plants for biofuels is controversial because the land, fertilizers, and energy for growing biofuel crops could be used to grow food crops instead. In some parts of the world, large areas of natural vegetation and forests have been cut down to grow sugar cane for ethanol and soybeans and oil palm trees for biodiesel.
Pyrolysis with biochar carbon sequestration provides a tool to combine sustainable soil management (carbon sequestration), and renewable energy production. While producing renewable energy from biomass, carbon sequestration, agricultural productivity, and environmental quality can be sustained and improved if the biomass is transferred to an inactive carbon pool and redistributed to agricultural fields.
The element is Si (Silicon)
More about Silicon
silicon (Si), a nonmetallic chemical element in the carbon family (Group 14 [IVa] of the periodic table). Silicon makes up 27.7 percent of Earth’s crust; it is the second most abundant element in the crust, being surpassed only by oxygen.
Silicon is a naturally occurring mineral. It's the second-most abundant element on earth after oxygen. Food sources include water, fruits, and vegetables.
Silicon supplements are sometimes used as medicine. It's not clear if silicon has a function in the human body. But there's some evidence it might have a role in forming bone and collagen.
People use silicon for weak bones (osteoporosis), aging skin, and many other conditions, but there is no good scientific evidence to support most of these uses.
Do not confuse silicon with silicone. Silicone is a group of materials resembling plastic that are used to make medical devices.

Answer:
0.5667 M ≅ 0.57 M.
Explanation:
- It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 1.5 M, V before dilution = 340 mL.
M after dilution = ??? M, V after dilution = 340 mL + 560 mL = 900 mL.
∴<em> M after dilution = (MV) before dilution/(V) after dilution</em> = (1.5 M)(340 mL)/(900 mL) = <em>0.5667 M ≅ 0.57 M.</em>
The nucleus is a membrane-bound organelle that contains an organism's genetic material and helps control and regulate cellular process.
The answer is nucleus(c)
