These structures have the function to move around.
Option: C
Explanation:
Tortoise is one animal who used to hide its body under a protective shell. To move its body parts take sharp bend and move around. It belongs to reptile family. It has four legs. Turtle's leg only appeared when it move on the land surface. It takes much time to move. Whole body remain under the shed of hard shell.
Turtles easily move into the water. They are good swimmer. They faced difficulties in moving on the ground mainly on undulating surface. They move very awkwardly. Their body weight is very heavy that is one of the problem in crawling.
Answer:
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants)
Explanation:
The correct answer is A. Nebula, star of seven stellar masses, a red supergiant, supernova, black hole.
Explanation
Stars have a life cycle that begins with the gravitational collapse of a gaseous nebula. Subsequently, thermonuclear fusion occurs that allows the conversion of hydrogen into helium, this causes the released energy to pass through the star and radiate in a phase called the star of seven stellar masses. After several billion years, the star passes to the "red giant" stage. Here the star contracts and raises its temperature. After this, the stars (which have masses greater than the sun) detach from their layers forming supernovae, and later, these give rise to "black holes". According to the above, the correct answer is A. Nebula, star of seven stellar masses, a red supergiant, supernova, black hole.
Answer:
The Circulatory System
Explanation:
When blood is rich in carbon dioxide it leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. (All of which have to do with the circulatory system)
