In the dicot stem, the vascular bundles are arranged in a ring, with pith concentrated at the core of the stem, rather than being scattered throughout the plant interior. In each vascular bundle, the xylem and phloem are separated by a substance called vascular cambium.
Answer:
Mafic or basaltic lavas are typified by their high ferromagnesian content and generally erupt at temperatures in excess of 950 °C (1,740 °F). Basaltic magma is high in iron and magnesium and has relatively lower aluminium and silica, which taken together reduces the degree of polymerization within the melt

The correct answer is option D, that is, the elephant will not react.
Explanation:
A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.
In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.
