Detailed explanation-1: -As part of regular biological processes, a deciduous tree: drops its functional leaves in the dormant season. Plants that complete their life cycles in two years are: Biennials.
Detailed explanation-2: -Just like phototropism, gravitropism is also caused by an unequal distribution of auxin. When a stem is placed horizontally, the bottom side contains more auxin and grows more-causing the stem to grow upwards against the force of gravity.
Detailed explanation-3: -A phylogenetic tree is a diagram that represents evolutionary relationships among organisms. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors.
