The Cell Membrane. Have a nice day! :)
The cell membrane is selectively permeable, allowing only certain substances to pass through. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion.
As the ribosome reads each codon of mRNA, it directs tRNA to bring the specified amino acid into the ribosome. Each tRNA molecule carries<span> just one kind of amino acid. In addition, each tRNA molecule has </span>three unpaired bases<span>, </span>collectively called the anticodon<span>—which is complementary to one mRNA codon.</span>
Adenine pairs with Thymine with two hydrogen bonds and guanine pairs with cytosine with three hydrogen bonds.
Answer: The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled pores. ... The ampullae pores are plainly visible as dark spots in the skin. They provide fish with an additional sense capable of detecting electric and magnetic fields as well as temperature gradients. The skate, a cartilaginous fish related to sharks and rays, possesses a unique electrosensitive sensory organ known as the ampullae of Lorenzini (AoL). This organ is responsible for the detection of weak electric field changes caused by the muscle contractions of their prey. brainliest
