"The drug naloxone can be used to counter the effects" of a heroin overdose by binding to opioid receptors and preventing heroin
Verizon [17]

Answer:

Naloxone is an antagonist at opioid receptors and heroin is an agonist at opioid receptors

Explanation:

An agonist is a substance that binds to a receptor and causes a biological reaction. In this case, heroine binds to opioid receptors. An antagonist blocks the reaction from the agonist, impeding the receptor's activation. Agonists and antagonists work for specific receptors, and for an antagonist to block an agonist they must bind to the same receptor, like naloxone does with heroin. Giving an antagonist that binds to one receptor and and agonist that binds to a different one means that the antagonist will have no effect.

Nonvascular plants have a system that transports water and nutrients throughout the plant’s body
solniwko [45]

Answer:

False

Explanation:

Plants, based on whether they can conduct water and nutrients, are classified into vascular and non-vascular plants. Vascular plants also called TRACHEOPHYTES are plants that possess certain special tissues called vascular tissues used for conducting water and nutrients in a plant. These conducting tissues are xylem and phloem.

On the other hand, non-vascular plants do not possess vascular or conducting tissues, hence, they cannot transport water and nutrients throughout the plant. Hence, such plants are naturally found in moist areas e.g. mosses. Therefore, based on the question asked, the answer is FALSE.
