Answer:

The second option is the answer: If elodea is put in a test tube in the dark with BTB, the BTB will turn yellow because photosynthesis will not occur in the dark, but the plant will be going through respiration releasing CO2.

Explanation:

Elodea is an aquatic plant that releases oxygen into its environment during the process of photosynthesis.

Elodea needs the requirements to carry out photosynthesis, but being placed in the dark it can not do so.

However it continues to carry out cellular respiration which results in the increase of carbon dioxide level in the water. This is indicated by the BTB turning yellow from green, the yellow colour is an indication of the higher amount of carbon dioxide present.

lakkis [162]

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.
