Answers

Answer:

Chemical spills, road salt, pesticides and fertilizers

Explanation:

Ground water pollution is addition of undesired substances to ground water that brings down its quality and makes suitable to be used by living beings. The chemical spills, road salt, pesticides and fertilizers get mixed with surface water and contaminate it. Percolation of contaminated surface water is the main cause of ground water pollution.

The next step in mass production of the protein would be _____________ of the bacterium containing the modified plasmid.

Answers

The correct answer for the question that is being presented above is this one: "Synthesized." A scientist isolates a gene from a human cell that codes for a specific protein. The gene is inserted into a bacterial plasmid in order to mass produce the protein for medical purposes. The next step in mass production of the protein would be synthesized of the bacterium containing the modified plasmid.

The answer is cloning.

Find the sum of a 9-term geometric sequence when the first term is 4 and the last term is 1,024 and select the correct answer below.A.682
B.2044
C.2048
D.678

Answers

First, we need to solve for the common ratio from the data given by using the equation.

a(n) = a(1) r^(n-1)
1024 = 4 r^(9-1)
256 = r^8
r = 256^(1/8)
r = 2

Then, we can find the sum by the expression:

S(n) = a(1) ( 1 - r^n) / 1-r
S(9) = 4 (1 - 2^9) / 1-2
S(9) = 2044

Therefore, the correct answer from the choices listed above is option B.
