Answer:
4. calcium ion and cAMP
Explanation:
Second messengers are the intracellular chemicals that are produced for signal transduction and generation of cellular response when a water-soluble hormone binds to its cell surface receptors. Since water-soluble signaling molecules such as protein hormones cannot cross the cell membranes of their target cells, their binding to the respective receptors triggers the production of an intracellular second messenger. The most common second messenger molecules are cAMP and calcium ions. For example, protein hormones bind to their G-protein linked membrane receptors and trigger the synthesis of cAMP in their target cells.
Answer:
hii there
how are you?
here's your answer
Explanation:
1 )
The five steps of the scientific method
Step 1: Ask a question or identify a problem. A scientist learns about the universe by observing
Step 2: Background research.
Step 3: Form a hypothesis.
Step 4: Experiment and observe.
Step 5: Draw a conclusion.
2 ) Matter is the stuff that makes up the universe everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Both atoms and molecules are held together by a form of potential energy called chemical energy.
3 ) Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the state of matter. The three fundamental phases of matter are solid, liquid, and gas.
hope it helps you dear
Mark my answer as brainlist
have a nice day dear : )
Answer:
300 meters/min
Explanation:
average speed = distance / time
(3000 m) / (10 min) = 300 meter per minute
if you need it in meters/sec then just multiply 10 by 60 first and then continue
(3000 m) / (600 sec) = 5 m/s
The answer is B hope this helps you:) I did this test yesterday
