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.

Answer:
interphase
Explanation:
Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.
There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include cell grows, DNA replicates and prepare itself for mitosis.
Hence, the answer is "interphase".
Answer: Carolus Linnaeus
Explanation:
Carlos Linnaeus created the binomial nomenclature system which gives scientific names to animals. Their genus and species is what classifies organisms.
Linnaeus also created the taxonomic system, which classifies organisms within different groups and subsets.

Answer:
D diffusion across a membrane
Explanation:
Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.
An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.
Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.
There are 4 thing that need to happen for natural selection to occur:
1) reproduction
2)heredity
3)variation in fitness or organisms
4)variation in individual characters of the population.
