Answer:
Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.
Answer:
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.

They live in a wide variety of moist habitats including fresh water, marine environments and the soil.
Answer:
They have tissues, organs, and organ systems.
Explanation:
While all animals are multicellular, heterotrophic, eukaryotic and ingest their food, not all animals have tissues, organs, and organ system.
<em>The simplest group of animals, the sponges, are made up of several cells that have minimal interaction with one another. Hence, while sponges are multicellular, they are not at tissue level of body organization.</em>
All the options are true for all animals except the last option.
Mutations in these genes can produce new or altered traits, resulting in heritable differences. Evolution occurs when different common or rare natural selection is genetically drifted.
