Answer:
3. liquid waste me directly into the ground water
Explanation:
Aquifer is a layer of water which is present inside the soil at a certain depth. There are certain areas where water is added to the aquifer and maintain the water level. These aquifers were polluted if liquid waste is dumped in these aquifer recharge areas and when this water is extracted through wells so health of both plants and animals are adversely affected. So for that reason liquid waste should not be dumped in recharge areas of aquifer.
Yes the following statements about her trout is likely true Because the ponds are different and the populations are likely to experience different mutations, the populations will likely diverge evolutionarily, but only over many generations.
Explanation:
The effect of genetic drift can be seen in all populations but the most is seen in small population. The change in allele frequency due to the sampling error would lead to evolution of the species.
Bottleneck effect is when a population gets reduced due to some natural disaster. Her friends were not right about bottleneck effect.
So it is clear that no bottleneck effect will occur as each pond have different chance or rate of mutation and the change in alleles will be different. The trouts will evolve independently in the different ponds and pass on the traits to their progeny.
Genetic drift does not take into account for the harm or benefit of the alleles that are passed on.
It will take <u>120 minutes</u> for the concentration to become > 15000 cells/cm³
<u>Given data:</u>
Initial concentration ( density ) = 1000 cells / cm³
Target/final concentration = > 15,000 cells /cm³
<h3 /><h3>Calculating the concentration every 30 minutes </h3><h3 />
<em>note</em><em> : Given that each cell divides every 30 minutes </em>
- <u>After the first 30 minutes </u>
Concentration = 2000 cells / cm³
concentration = 4000 cells / cm³
concentration = 8000 cells / cm³
- <u>After 120 minutes </u>
concentration = 16000 cells / cm³
Therefore after 120 minutes the concentration of the cells will be greater than 15000 cells/cm³ ( i.e. 16000 cells/cm³ )

Answer:
If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
It would have been a little helpful if you added a picture but I hope this is helpful.Thank you!
