Suppose That Botanists Have Discovered a New Plant Hormone and They

question 19

Multiple Choice

Suppose that botanists have discovered a new plant hormone and they hypothesize that it is required for normal leaf shape.Which experimental result would not support this hypothesis?

• A) A mutant with abnormal leaf shape is found to lack the hypothesized hormone.
• B) A chemical that is isolated is found to affect leaf shape when applied to the young tip of developing plants.
• C) Plants in which the synthesis of the hypothesized hormone is inhibited develop abnormal leaves.
• D) Removal of the young tip of the plant causes the development of abnormal leaf shape.
• E) Treatment of a leaf-shape mutant plant with the hypothesized hormone restores normal leaf development.

Definitions:

Axon

The long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body to other neurons or muscles.

Action Potential

A sudden, temporary reversal of the electrical charge across a neuron's plasma membrane, allowing neurons to transmit signals over long distances within the body.

Axon Hillock

The axon hillock is the part of a neuron that connects the cell body to the axon, playing a crucial role in the initiation of nerve impulses.

Magnitude

Magnitude typically refers to the size, extent, or dimension of an object or phenomenon, often quantified in terms of numerical values in various scientific fields.
