D; because the cells dna is not in the nucleus
1. water temperature of lakes and rivers rise - nuclear power plant. Water is used as a coolant to maintain the temperature of nuclear reactors. and the resulting water is warmed up.
<span>
2.carbon monoxide pollutes air - </span> internal combustion engine. Internal combustion engines release fumes of carbon monoxide.
<span>
3. fly ash of soot in air - </span>coal-burning power plant. Coal burning plants release ash produced in small dark flecks.<span>
4. soil contamination of water resources - </span>DDT spraying in agriculture. DDT washes off agricultural land into water resources.
<span>
5. sewage contamination of water resources -</span>population density. Urban areas produce a low of sewage, which is usually treated before being disposed of in rivers or the sea.
<span>
6. excess plant growth in the lakes or rivers - </span>phosphate detergents. In many rivers, algal growth is limited by phosphate. Once excess phosphate is released to rivers, exponential algal growth can occur.<span>
7.reduces farmland and plant life to cleanse air - </span>urban sprawl. Urban sprawl uses up land for houses in an inefficient manner that could have been used for farming or natural areas.
<span>
8. studies air,water, and land - </span>ecologist. Ecology is the study of <span>relations of organisms to one another and to their physical surroundings.</span><span>

Answer:
The scientific mrthod is a process used by scientists to find answers to a question or to solve a problem. No there isn't just one because there are several versions of the scientific method. Some versions have more steps, while others may have only a few. Scientists can add steps, take out steps, revise, or make models.
Answer:
cell wall) function:protects and holds the structure of the cell
X for plant cell
chloroplast) absorbs energy from sun through photosyn. to make nutrients
plant cell-x
cytoplasm) a gel like substance in which most of the cell's processes take place
x for plant&animal
ER) packages & transports proteins made by ribosome to the golgi apparatus
GA) transports proteins to their destined location throughout the cell
found in plant and animal cells
Mitch) converts energy in nutrients to usable energy
found in plant and animal cell
nucleus: stores and protects DNA
found in plant and animal cells
vacuole: stores food and water
found in plant and animal cells
