<h2>Answer:</h2>
<u>The objects that allow humans to access ground water are:</u>
- <u>A spring</u>
- <u>a well drilled into an aquifer
</u>
- <u>a well drilled below the water table</u>
<h2>Explanation:</h2>
Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..
Antibiotics are, initially, molecules naturally synthesized by microorganisms to fight against bacteria competing with their environment. This created a pressure of selection on the bacterial populations, leading to the appearance of resistant strains. In fact, when an antibiotic is used, only bacteria with defense systems against this molecule survive (and reproduce).

The answer is; DNA
The central dogma is DNA- RNA- Protein
Gene therapy involves the replacement of bad genes in the DNA of a human subject with a better gene. A recessive/mutated allele is removed and a healthy one is inserted. This way, the proper proteins can be produced solving the disease trait. Ultimately, it will not require drugs to treat the disease.
Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity, 
= 
Pupil has a diameter, d = 8.5 mm
= 8.5 x 
m
Radius of the eye, r = 4.25 x m
∴ Area of the eye, A = 
= 
= 
Let 
be the minimum number of photons.
Therefore, = x A
= 
x 
= 
W
Thus the minimum number of photons is given by
where E = 
= 
= 
Therefore, 
= 
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
Grass often dies near roads that have been <span>salted to remove ice during the winter because the salt spread out into layer of the grass </span>cell. Then the water goes into the ice because the grass is attracted to the salty ice water. Hence, this dehydrates the plant cell by removing excess water, so it dies since it can no longer perform the proper cell function.<span> </span>
