Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)

Degger [83]

Answer:

Thyroid hormones      

Explanation:

Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have shown to be affected by their effect on the thyroid. These chemicals can produce endocrine alterations acting as thyroid disrupters. They affect many mechanisms in the organisms such as inhibition of thyroid iodine uptake, <u><em>interference with the thyroid hormone receptor</em></u>, binding to transport proteins, among others. They cause toxicity in the functioning of the hypothalamic-pituitary-thyroid axis.

There are many studies that associate thyroid diseases with exposure to organochloride pesticides. Significant alteration in the TSH, T3, and T4 levels have been expressed by people directly or indirectly exposed to the chemicals.
