Answer:
The correct answer is (b) epinephrine.
Explanation:
Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.
In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.
When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.

<span>The answer that is seemingly true, based on the information given, is: Those that preys on blue crabs would opt to a new prey changing the food web. This occurrence was the reason why some of the organisms die because of the decreased number of blue crabs.And eventually, those that are preyed on by the blue crabs would likely to grow their size.</span>
<em>Active transport</em><em> uses </em><em>cellular energy</em><em> to </em><em>move molecules</em><em> based on the </em><em>concentration level</em><em> and </em><em>Passive transport doesn't</em><em> require </em><em>energy</em><em> to </em><em>move molecules within</em><em> their </em><em>cells</em><em>.</em>
<u>EXPLANATION: </u>
Active transport uses cellular energy for this movement. It uses energy stored in ATP to begin the transport. This means that the molecules transfer from an area where it is less in number to an area with a high concentration of molecules.
But Passive transport specifies the movement of molecules across cell membranes which doesn't require energy as it depends on the cell membrane's penetrability. Molecules just have to circulate in or out of the cell.
Crustaceans Insects <span>Arachnids belongs to phylum arthopoda and insects have both wings and antennae whereas crustaciens like crab shrimps have no wings but antennae and archanids have none of them
</span>so correct option for statment
<span>The species of which of these groups show neither wings nor antennae is
C
