1. Describe what DDT is and how does it impact the food web. 2. Do you think humans health can be affected by hazardous bioaccumulates in an ecosystem? Make sure you explain using a statement from the reading. 3. Do you think DDT is the only bioaccumulate that can affect the food webs of an ecosystem?

1. DDT may alter the central nervous system of the animals living in an ecosystem contaminated with this synthetic insecticide, thereby affecting their food relationships

2. Yes, indeed it has been shown that the incidence of deaths by cancer is significantly higher in areas where DDT is used as an insecticide. Moreover, it also been shown that this compound alters the endocrine system of most animals.

3. DDT is a synthetic biomolecule insoluble in water and persistent in the environment, and it is therefore a severely hazardous formulation. Persistent organic pollutants include synthetic organochlorine pesticides (for example, DDT), industrial chemicals, especially toxic polychlorinated biphenyls such as those used in insulating fluids for transformers and capacitors and industrial hazardous substances, including polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF).

Explanation:

(DDT) is an organochlorine substance originally used as an insecticide, which became infamous due to its environmental impacts. In 1972, the US banned the use of DDT; however, there are countries that still use it as an insecticide for the control of mosquitoes in endemic malaria areas.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

no i don't feel that humans have oversubscribed some medications
