Answer:
Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.
Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.
But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.

THE HIDDEN COSTS OF TURNING FOOD INTO FUEL
Explanation:
The biofuels are Natural gas, Ethanol and Biodiesel. These are all the correct options.
What are biofuels?Biofuels are the fuels derived from biological sources such a plants and algae rather than from the fossil fuels. They are considered to be a renewable energy source, as the raw materials used to produce them can be replenished relatively quickly.
There are several types of biofuels:
BioethanolBiodieselBiojet fuelBiomethaneOverall, the use of these fuels are considered to be a promising solution to reduce dependence on non-renewable fossil fuels and to reduce green house gas emissions in the transportation sector. Awareness should be created in the public for the utilization of the biofuels so that it is used more and more and reduce the pollution caused by fossil fuels.

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution
Answer:
Cytochrome c is known to play a role in the electron transport chain and cell apoptosis. However, a recent study has shown that it can also act as an antioxidative enzyme in the mitochondria; and it does so by removing superoxide (O2–) and hydrogen peroxide (H2O2) from mitochondria.Therefore, not only is cytochrome c required in the mitochondria for cell respiration, but it is also needed in the mitochondria to limit the production of O2– and H2O2.

All of the following can take material into cells except
O active transport
O exocytosis
O endocytosis
O passive transport
Answer:
The correct answer is - exocytosis.
Explanation:
All of the given options of the transport mechanism are the transport of the substances either into the cell or out of the cell or both. Active transport is the transport mechanism that involves the transports of substances from the lower concentration region to the higher concentration region and utilize energy.
Endocytosis and exocytosis are the forms of active transport, however, endocytosis involves taking material into the cell and exocytosis out of the cell. Exocytosis is the form of active transport as it requires energy to moving materials from within a cell to the exterior of the cell.
