For the answer to the question above, the answer is "Systemic Acquired Resistance''.
<span>it is a whole-plant resistance response and it occurs by following an earlier localized exposure to a pathogen. It is analogous to the innate immune system that can be found in the animals, and there is also an evidence that SAR in plants and innate immunity in the animals may be evolutionarily conserved.</span>
Answer:
Human activities affect the flow of energy and matter in an ecosystem and alter the energy balance in ecosystems through the unsustainable nature of what they do. The energy flow is affected in several ways as a result of pollution, overpopulation, deforestation, burning fossil fuels, etc. Such changes have stimulated soil erosion, climate change, causing water unfit to consume, poor quality of air and so on. When humans cause a change in the energy balance, they impact the ability of the ecosystem to respond and adapt to changes in the environment. It is like getting a cut, but it never heals and grows bigger instead.
Smelt would have the quickest increase because the perch would no longer be eating them.
The southerly lowlands of the island average around 0 °C<span> (</span>32 °F) in winter, while the Highlands of Iceland tend to average around −10 °C<span> (14 °F). The lowest temperatures in the northern part of the island range from around −25 to −30 °C (−13 to −22 °F). The lowest temperature on record is −39.7 °C (−</span>39.5 °F<span>).</span>
The best answer would be the butterfly. Many insects go through different physical changes during growth. These insects include the butterfly. From being an egg it turned into a larva and grown into a caterpillar which later on become a butterfly.
