adoni [48]

Answer:

D. Cup 4 had the lowest rate of photosynthesis because it had the least CO2.

Answer: There are many relationships between the organizational levels of the environment. All of them compliment each other in order to make everything work.The biosphere is what puts everything all together. It is were all live resides. The community,population and organisms are all in the biosphere. The organisms become the population and then the population becomes the community from all the little organisms around. All of these live in biomes and ecosystems. In those areas is where the population and communities live from all the organisms around. Without the biomes and ecosystems there would be no communities nor population and especially no organism's because there'd be no place to call home.

An example of a density-dependent factor is food. Without food the population will die due to starvation. With food the population will strive. A density-independent factor is a disease. The disease will kill of the whole population no matter it's size.

In primary succession is when a newly untouched habitat is occupied. For example a newly grown plant. This plant will soon be taken over by an insect as its temporary home. Once the plant dies the insect leaves. Then the remains of the plant become secondary succession as it is taken over by for example worms in the soil.

In case, the patient is detected with the intrathoracic infections, a foul odour can be easily detected in the breath.

So, the nurse should check for the presence of foul odour.
