Only the last one provides an actual evidence of having a common ancestor. The rest can be a result of living in a similar environments that makes life easier. For example, many species live next to water, as water provides more fertile ground for plants, and they might have similar behaviors (searching for water) but they might not be closely related.
so the correct answer is D.
Bacteria can be genetically engineered for many purposes. That is really dangerous and can harm people by creating something new without knowing what it is.
Feel free to ask me questions and hope that helps:)

Answer:Living organisms release energy gradually to prevent most of the energy from heat loss. The cells release the chemical energy present in food and it should be utilized gradually to prevent the energy loss in the form of heat and light.Most of the energy released by the body is through cellular respiration.The energy is produced by the continuous process that occurs in the body ,breakdown of food and energy production.If a huge amount of energy will be released from the body it will only be in the form of heat loss so to prevent the energy from lost in the form of heat living organism release energy gradually
The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.
Answer:
uh well i can guess for you because i think i know,
1. physical change
2. water if heated up can change into a gas.
3.yeah
4.because the two hydrogen or whatever mixed with the one oxygen or whatever created two whatever
im pretty big brain as you can tell.
