The statement that correctly compares synthesis and decomposition reactions would be that <u>synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form A + B → AB, while decomposition reactions are in the form AB → A + B.</u> Thus, A would be the right option.
In synthesis reactions, two different atoms combine to form a compound, such that:
A + B ---> AB...................equation 1
In decomposition reactions, a compound or molecule disintegrates to form two different atoms or molecules, such that:
AB ---> A + B......................equation 2
Equation 1 is essentially the opposite of equation 2. Thus, it can be said that synthesis and decomposition reactions are opposites of each other.

Answer:
A. exposure - use of artificial sweeteners
disease - bladder cancer
In this research artificial sweeteners are used as the exposure that leads to bladder cancer disease.
B. Bladder cancer No bladder cancer
Artificial sweeteners 1293(a) 855(b)
No artificial sweeteners 1707(c) 2145(d)
Total 3000 3000
Cases -
- Risk factor (Artificial sweeteners) present (1293)
- Risk factor (Artificial sweeteners) absent (1707)
Controls
- Risk factor (Artificial sweeteners) present (855)
- Risk factor (Artificial sweeteners) absent (2145)
Odds ratio or strength of association between exposure and disease
OR= Cases with exposure/cases without exposure= a/c divided by b/d
So, the putting value ad/bc= 1293*2145/855*1707
= 1.9
OR would be 1.9
C. this interprets that there is a 90% increase in the chance of bladder cancer if exposed to artificial sweeteners or people with bladder cancer have a 1.90 times higher odds of using artificial sweeteners compared to controls
Answer.Nucleotides Have Characteristic Bases and Pentose. Nucleotides have three characteristic components: (1) a nitrogenous base, (2) a pentose, and (3) a phosphate (Fig. ... The nitrogenous bases are derivatives of two parent compounds, pyrimidine and purine (Fig. 12-lb).
Answer:
Because genetic engineering is no longer based off the natural science of life it is humanly modified which concerns the ethical reasoning of human life and can lead to non humanly right creations

Chlorinated hydrocarbons is the group these pesticides belong to
