Which two animals use echolocation?

bats and humans

bats and dolphins

dolphins and humans

dolphins and butterflies

The correct answer is -

bats and dolphins.

Echolocation (also termed as biological sonar) can be described as the ability of some animals to detect objects present in their environment by sensing echoes and sound waves of those objects.

Dolphin use echolocation to see various organisms/objects better underwater.

Bats loctate their food during dark by sending sound waves, which hit a food source/an object and bounces back, producing echo that is ultimately sensed by bats.

the cytokine-activated janus kinase (jak)-signal transducer and activator of transcription (stat) pathway has an important role in the control of immune responses. dysregulation of jak-stat signaling is associated with various immune disorders.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
