How do sharks detect electric fields?
Many marine animals, from tiny clams to big fish, produce electric signals. Sharks and other ocean predators, including skates and rays, sense those electric fields. They do it using organs known as ampullae (AM-puh-lay) of Lorenzini. Scientists call such tissues electroreceptors because they detect electric fields.

Does First Response detect low hCG?
One kit, the First Response Early Result Pregnancy Test, emerged as the most reliable and sensitive test. “It detected hCG at concentrations as low as 6.5 mIU/ml (thousandths of an International Unit per milliliter) – that’s almost sensitive enough to detect any pregnancy soon after implantation,” CR wrote.

How do sharks detect weak electric fields?
The elasmobranchs-sharks, rays, and skates-can detect very weak electric fields in their aqueous environment through a complex sensory system, the ampullae of Lorenzini. The ampullae are conducting tubes that connect the surface of the animal to its interior.
Can a pregnancy test be positive at 1 week pregnant?
To help ensure an accurate result, the best time to take a pregnancy test is 1 week after a missed period. Results of a pregnancy test are either positive or negative.
