Question

A previously used form of the insecticide ddt (dichlorodiphenyltrichloroethane) caused birth defects in future conceptions of exposed women, such as misplacement of limbs and eyes on the body. describe what was affected by these stimuli

Answer 1

Answer:

Insecticide DDT(dichlorodiphenyltrichloroethane) have a very harmful effect on the stimuli because it can not be broken down by decomposers such as bacteria and fungi and remain on the surface for a long period of time.

Explanation:

This insecticide is used for controlling pest population in the field but now it is banned around the world due to its harmful effects on humans and other living organisms. This chemical is non biodegradable i. e. cannot be decompose into simpler substances by the action of bacteria and fungi and causes chronic diseases in humans.

Answer 2

Answer:Insecticide DDT(dichlorodiphenyltrichloroethane) have a harmful effect on the stimuli because it can not be broken down by decomposers such e.g bacteria and fungi. Therefore, remaining on the surface for a long period of time (i.e it's non biodegradable).

Explanation:

DDT was an organochlorine insecticide used mainly to control mosquito-borne malaria, but has been banned in US and other countries due to its harmful effects on humans. It's not biodegradable, like I said earlier, it's not capable of being decomposed by biological activity, especially by microorganisms.The chemical breaks down of DDT is very slow and accumulates in the fatty tissues of animals (including people).

DDT is an endocrine disruptor, meaning it acts like a hormone or affects how other hormones act in the body. This endocrine disruptors throw off the body’s hormonal balance by blocking or mimicking hormones, such as estrogen in the woman body. Studies have shown that DDT is linked to birth defects.
