Which question would be asked in a dichotomous key?
how long are the insect's antennae?
are the insect's antennae longer than its head?
are the insect's antennae long or short?
how does the insect use its antennae?

Are the insects antennae longer than its head.

Explanation:

Are the insect's antennae longer than its head?

Explanation:

This character is easily measurable and allows insects to be grouped into two groups, those that have the antennae longer than their head and another group of those that have the antennae shorter than their head. A dichotomous key is based on the fact that two possible solutions start from it, depending on whether or not they have a certain character, and it needs to be constructed by pairs of opposing statements like in this case antennae longer than its head and shorter are opposite

explanation:

mitosis is used to produce daughter cells that are genetically identical to the parent cells. the cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
