NO ALL INSECTS ARE NOT HARMFUL
Not all bugs are bad. Insects get labeled as "pests" when they start causing harm to people or the things we care about, like plants, animals, and buildings. Out of nearly one million known insect species, only about one to three percent are ever considered pests.

The cell surface membranes of cells of flower, though semi-permeable, allows water to pass through cell via aqua proteins embedded in the membrane.
This is true since water goes from inside of cell to the extracellular environment when water potential inside the cell is higher than water potential outside the cell via process of osmosis (water goes from an area of high water potential down a concentration gradient to an area of low water potential). Cells in the flower became plasmolysed (cell surface membranes tear away from the cell walls) as the volume of water in cell decreases.
Hope this helps! :)
Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
The new species can be formed in one of the three ways that are allopatric, peripatric, and parapatric speciation.
The allopatric speciation gives rise to new species due to the geographical barriers present between them and the peripatric speciation occurs when a small population enters into a new habitat.
In the given question, species A is more closely related to species B as to species C. This could be due to the allopatric speciation or peripatric speciation but it would depend on the number of the individuals of the population that dispersed to a different elevation which provided a new niche.
Thus, the selected option is correct.
Answer:
The arrow should be pointing from the producer towards the consumer.
Producer --> Consumer
Explanation:
The arrow represents the flow of energy in a food web. Producers are the first source of energy, as they make their own food. The energy is then transferred to the consumer when they eat the producer. For example, if a cow were to eat grass, the energy would flow from the grass to the cow. The arrow shows how this energy is flowing from the first source to the second.
