Answer:
C. After running 20 miles
Explanation:
Anaerobic respiration only occurs when an organism lacks all the oxygen we need to function. After running 20 miles, you will be out of breath, and you will have been using more energy than your respiratory system could produce alone. Due to this, your body will start using some of your energy stored within cells in order to continue functioning. This kind of respiration is basically 'burning calories'.
The correct answer is the third one
they were classified as echinoderms and not as a new phylum because they have the attribute of the echinoderm where they were seen as the sea stars without arms, they live in the deep ocean.
<h3>What is an
echinoderms?</h3>
An echinoderm can be described as the any member that can be attributed to the phylum Echinodermata.
The members of this family can be seen as one that posses a recognisable radial symmetry which help in the process of their classification, and some of the members that fall into this caetegories are:
- starfish
- brittle stars
- sea urchins
- sand dollars
- sea cucumbers
- "stone lilies
It should be noted that the phylum can be seen as the level of classification or taxonomic rank that can be seen below kingdom.
In conclusion, the Sea Daisies which was thenew class of echinoderm that was discovered in 1986 can be classified as the echinoderm and not as phylum since they have the feautures of the echinoderm.

Explanation:
(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line
(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards
(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move
(4) I think it's both Newton's second law and third law motion.
I hope these helps
