Read the following passage carefully:
Without specialised equipment, humans would be lost in these deep-sea habitats, so how do fish make it seem so easy? Much of this is due to a biological phenomenon known as electroreception the ability to perceive and act upon electrical stimuli as part of the overall senses. This ability is only found in aquatic and amphibious species because water is an efficient conductor of electricity.
One fascinating use of electroreception has been observed between the weakly electric fish. When two such electric fish meet in the ocean using the same frequency, each fish will then shift the frequency of its discharge so that they are transmitting on different frequencies. Doing so prevents their electroreception faculties from becoming jammed.
Electroreception can also play an important role in animal defences. Rays are one such example. Young ray embryos develop inside egg cases that are attached to the sea bed. The embryos keep their tails in constant motion to pump water and allow them to breathe through the egg’s casing. If the embryo’s electroreceptors detect the presence of a predatory fish in the vicinity, however, the embryo stops moving (and in doing so, ceases transmitting electric currents) until the predator has moved on.
Many people fear swimming in the ocean because of sharks. Sharks hunt with extraordinary precision. They initially lock on to their prey through a keen sense of smell. As the shark reaches the proximity of its prey, it tunes into electrical signals that ensure a precise strike on its target. This sense is so strong that the shark even attacks blind by letting its eyes recede for protection. In areas where shark attacks on humans are likely to occur, scientists are exploring ways to create artificial electroreceptors. These would disorient the sharks and repel them from swimming beaches.

1. As a young adult, life can be stressful and overwhelming at times. Juggling among school, work, social life, and other responsibilities, it can be easy to feel alone and disconnected from the world around us. Dogs are the ultimate companions for anyone looking to alleviate stress and loneliness. We’ll explore many reasons why dogs make the best companions for young adults.
Unconditional love: Dogs are known for their loyalty and love for their owners, no matter what. They don’t judge us, criticize us, or hold grudges against us. No matter how flawed or imperfect we may be, our dogs will always love us unconditionally. This kind of unwavering support and affection can be incredibly comforting for young adults struggling to find their place in the world.
3. Social connection: Dogs are great ice-breakers and conversation starters. Whether you’re walking them in the park, taking them to the dog beach, or simply hanging out at home, dogs have a way of bringing people together. For young adults who may feel isolated or disconnected from their peers, having a dog by their side can be a great way to connect with others and form new friendships.
4. Increase physical activity: Dogs require regular exercise in order to stay healthy and happy. This means that young adults who own dogs are more likely to engage in physical activity themselves. Whether it’s going for a run, playing frisbee, or simply taking a leisurely stroll, getting out with your dog can be a great way to boost your mood and energy levels.
5. Emotional support: Dogs are also great emotional support animals for those struggling with mental health issues such as anxiety and depression. Their presence alone can provide a sense of calm and comfort, and their ability to sense their owner’s emotions can be incredibly comforting. For young adults dealing with mental health challenges, having a dog as a companion can be a life-changing experience.
6. Improve responsibility and self-care: Owning a dog also comes with a great deal of responsibility and self-care. Dogs require regular feeding, grooming, exercise, and attention, which can be a great way for young adults to develop a sense of responsibility and self-discipline. Additionally, having a dog as a companion can encourage young adults to take better care of themselves, such as making sure they get enough sleep, eat healthy, and engage in regular exercise.
7. For all these reasons and more, dogs make fantastic companions for young adults. Whether you’re looking for emotional support, social connection, increased physical activity, or simply someone to love and be loved by, a dog can provide all these things and more. So the next time you’re feeling stressed or overwhelmed, consider finding a furry friend to take on the world with you.
