Some species of dolphins find their prey by echolocation; they emit clicking sounds and listen for echoes returning from distant

objects in the water. Marine biologists have speculated that those same clicking sounds might have a second function: particularly loud clicks might be used by the dolphins to stun their prey at close range through sensory overload. Which of the following, if discovered to be true, would cast the most serious doubt on the correctness of the speculation described above?
(A) Dolphins that use echolocation to locate distant prey also emit frequent clicks at intermediate distances as they close in on their prey.
(B) The usefulness of echolocation as a means of locating prey depends on the clicking sounds being of a type that the prey is incapable of perceiving, regardless of volume.
(C) If dolphins stun their prey, the effect is bound to be so temporary that stunning from far away even if possible, would be ineffective.
(D) Echolocation appears to give dolphins information about the richness of a source of food as well as about its direction.
(E) The more distant a dolphin's prey, the louder the echolocation clicks must be if they are to reveal the prey's presence to the hunting dolphin.

Answer:

(B) The usefulness of echolocation as a means of locating prey depends on the clicking sounds being of a type that the prey is incapable of perceiving, regardless of volume.

If the prey can't really hear the echolocation, there is no potential for "sensory overload," which would discredit the theory that they stun their prey. It sounds pretty cool, but I feel like the speculation is probably unfounded.

The cytoplasmic extensions that, together with the cell body, provide the main receptive surfaces for neurons are the
Harlamova29_29 [7]

Answer:

The correct answer will be option- D.

Explanation:

Neurons are the cells which help in the transmission of the signals to and fro from the CNS and PNS to the body and vice versa. The structure of the neurons is divided into three main parts: the axon, dendrites and the cell body. The dendrites and axons are the extensions of the cell cytoplasm and together constitutes the neurites.  

The dendrites are the extensions of the cytoplasm which receives the signals either from the cell surface as well as the from the post-synaptic neurons and further process the signals.

Thus, option- D is the correct answer.

The frontal lobes also include the primary ____________ which controls voluntary motor functions.
lakkis [162]

Answer:

The correct answer will be- primary motor cortex

Explanation:

The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain.  The motor cortex is thought to be involved in the planning actions and control voluntary actions.

The motor cortex is divided into three regions: premotor cortex, primary motor cortex  and supplementary motor area.

The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.

Thus, the primary motor cortex is the correct answer.
