Answer:
Aerobic activity
Explanation:
Aerobic activity can be defined as a type of physical activity which involves the the circulation of oxgen through the blood.
Aerobic activity is an activity which increases the amount of blood that goes to the muscles. Oxygen is needed for the proper functioning of the muscles.
When carrying out any type of physical activity such as weight lifting the muscles need a large amount of oxygen to function well. The oxygen in the body is used to break down glucose and create the fuel which is needed by the muscles in the form of ATP. Different aerobic activities carried out also helps to strenthen the lungs.

Answer:
deuterostomes
Explanation:
During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.
