Answer:
Release carbon dioxide
Explanation:
Animals breathe in oxygen and release carbon dioxide
Answer:
It is also worthy to note that Mendeleev's 1871 arrangement was related to the atomic ratios in which elements formed oxides, binary compounds with oxygen whereas today's periodic tables are arranged by increasing atomic numbers, that is, the number of protons a particular element contains.
Explanation:
They are renewable natural resources. They move round and round in cycles and never run out. For example a horse eats a plant the horse gets eating by another animal the cycle goes on an on an on
Answer:
it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading and Compass housings are often made of either brass, aluminium or plastic.
Explanation:
The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
Secondly it would confuse the magnet thereby making it un-useful or useless because the iron can easily become magnetized itself and Iron is a magnetic metal which can cause the needle of a compass to give a false reading thereby messing up the magnet's direction and making it useless.
Both plant and animal cells have membranes so whatever chemical reactions they have going inside the cell, it is regulated and maintained. Membranes help separate the internal environment from the external environment.
Hope this helps - I'm currently in cell biology so this question is interesting
