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: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.
Hmm due to some thinking and having some knowledge of the body. I believe the crani refers to the skull. Crani could be considered short for cranium which refers to the skull. I hope that this helps!
Gas exchange of oxygen and carbon dioxide takes place in the alveoli<span>. Oxygen from the inhaled air diffuses through the walls of the </span>alveoli<span> and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.</span>
C. esophagus. it does not secrete any enzymes. its just do peristalsis. which is a rhythmic contractions and relaxations of muscles to push food along the gut
<span>To get energy. Sugars are particularly important fuel molecules. They are oxidized in the food we eat and must be broken down into smaller molecules before our cells can use them
