Gene testing is foolproof since it scans the building blocks of humans. Please select the best answer from the choices provided.
Harrizon [31]

False

reason -

Gene testing is not full proof as there are  possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof

Identify the mutagenic effects of deaminating agents, alkylating agents, and base analogs.
Mila [183]
<span>All are mutagenic because they cause base substitutions, deaminating agents oxidatively deaminate bases so cytosine converted to uracil and adenine converted to hypoxanthine, uracil pairs with adenine and hypoxanthine pairs with cytosine, alkylating agents donate alkyl group to amino or keto groups altering base pair affinities</span>

C. How many grams of NaOH (sodium hydroxide) are necessary to make 100
azamat

18 g

Explanation:

Remember that 1g is equivalent to 1 ml;

1g = 1 mL

100 g = 100 mL

Therefore in an 18% NaOH solution,  for every 100 mL, there is 18 g of dissolved NaOH. This is how we derive the percentage solution;

18 g / 100 g = 18%

Unlike life at the top of a body of water, life at the bottom of the body of water
Nikitich [7]
At the top of the body of a water, there is a lot of light from the sun, which also means a lot of solar energy. This allows for a fruitful photosynthesis.

In contrast, at the bottom of the water, there isn't as much, or sometimes any, sun light. Because of this the organisms at the bottom of the body of  water
<span>D. must rely on other means than photosynthesis </span>
