OBJECTIVE FORESTRY

Detailed explanation-1: -Resistance is the ability of one or more organisms to tolerate a particular chemical designed to kill it. An organism may be resist-ant to a chemical when it contains a gene that allows it to break the chemical down into harmless substances.

Detailed explanation-2: -Farmers spray higher doses of pesticide if the traditional dose doesn’t kill, so genetic mechanisms that enable the pests to survive the stronger doses rapidly become widespread as the offspring of resistant individuals come to dominate the population.

Detailed explanation-3: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-4: -Euglena are protists that can feed like an animal or use the energy of the sun to make food like a plant. The cells of protists need to perform all of the functions that other cells do, such as grow and reproduce, maintain homeostasis, and obtain energy.
