C is the correct answer. The universe is always changing with new stars and more carbon dioxide. Any around 23% isnt new
B) oxygen
Respiration is defined as the movement of oxygen from the outside air to the cells within tissues
As a person pushes a box across a floor, the energy from the person's moving arm is transferred to the box, and the box and floor become warm during this process, energy is conserved.
Explanation:
This process happens because of conservation of energy. According to the rule of the conservation of energy. Energy can’t be created not destroyed. It simply transformed or converted from one form to another. It simply means this system always need same amount of energy.
When a person moving arm is to transferred into box is form of kinetic energy and on the same way when then floor and box becomes warmer it converts into heat energy. Here the energy transformed into one to another form.
So basically its like every animal has all the leading characteristics. for example, you marked that the shark has a vertebra that is correct now you would go onto the Ray-finned fish, you would follow the cladogram lines and x off Vertebra and Bony skeleton you had this correct as well. Now going onto the Amphibians, you would follow the lines again as before and x off everything you've already ticked off plus four limbs because it falls underneath. you would do this for every category and characteristic. Hopefully, this makes sense!! The rest after Amphibians needs to be revised its not correct. :)
Answer:
Waves carry energy from one place to another. Because waves carry energy, some waves are used for communication, eg radio and television waves and mobile telephone signals. There are many types of waves including sound waves, water waves and all the parts of the electromagnetic spectrum.
