Answer:
True.
Explanation:
Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.
Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.
Enkephalins and endorphins act on the  mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.
Hence, Enkephalins and endorphins are peptides that act like morphine.

Answer:
If sunspots are active, more solar flares will result creating an increase in geomagnetic storm activity for Earth. Therefore during sunspot maximums, the Earth will see an increase in the Northern and Southern Lights and a possible disruption in radio transmissions and power grids.
 
        
             
        
        
        
The following goal the U. S. Integrated Ocean Observing System (IOOS) is not intended to address is to promote ocean ownership.
<h3>What is the Integrated Ocean Observing System?</h3>
The United States' Integrated Ocean Observing System, is a network of people and technology.
It collaborates to collect and transmit data on our coastal waters, Great Lakes, and seas. 
Some of its work is gathering data in the ocean, while others are on land or in space.
Thus, the correct option is C, which promotes ocean ownership.

<span>The answer is C.glycolysis ® Krebs cycle ® electron transport chain. There are 3 stages of cellular respiration: 1. glycolysis when glucose is broken down to pyruvate in the cytoplasm; 2. Krebs cycle when Acetyl CoA and oxaloacetate form a 6 C-atoms compound; 3. Electron transport chain when hydrogen molecules removed through previous stages are pumped to the chain and energy is produced.</span>
