Analyzing the Relationship Between
Lead Exposure and Mental Ability
Background
Lead is a heavy metal that can cause a variety of symptoms when it enters the human body. Lead interferes with the development of the nervous system and can cause headaches, confusion, irritability, and in severe cases, seizures, comas, and death. Lead has also been linked to learning and behavioral disorders. Lead can enter the human body through contaminated air, food, water, soil, or in manufactured products such as paint.
The Centers for Disease Control (CDC) have set the acceptable level of lead to 10micrograms/deciliter. The following data shows the results of a fictitious study of children born and raised in a town near a lead smelter. The blood levels of lead and IQs of the children were all measured at different ages.
Pedanius Dioscorides observed the effect of lead on the mind in the first century A.D.
Part 1 - Prior to exploring the collected data, answer the following questions:
Form a hypothesis about the relationship between lead levels in blood and IQ. Will this effect be consistent for all age levels, or will it affect certain age groups differently?
_____________________________________________________________________________
_____________________________________________________________________________
_____________________________________________________________________________
Given that the children are living near the lead processing plant, what do you think are the likely ways the children were exposed to the metal? Describe two possible routes of exposure.
____________________________________________________________________________
_____________________________________________________________________________
_____________________________________________________________________________
_____________________________________________________________________________
Would you classify the lead exposure of the children as chronic or acute? Explain.
_____________________________________________________________________________
_____________________________________________________________________________
_____________________________________________________________________________
In this study, what would be considered the independent and dependent variable? The independent variable is selected or controlled as part of the study. The dependent variable is measured or observed as a result of the independent variable.
_____________________________________________________________________________
_____________________________________________________________________________
_____________________________________________________________________________
Ans:
Part 1: The hypothesized relationship between blood lead concentrations and IQ This effect is not consistent across ages and affects different ages to different degrees.
Part 2: Younger people, namely children, are more or more at risk because lead affects their mental development more than adults because the nervous system is still developing in childhood and is therefore more sensitive to unwanted events.
Part 3: Two possible exposure exposures.
Respiratory pathway - Lead processing plants emit smoke containing small particles of the metal lead, which is inhaled by children and exposed to this hazardous metal.Ingestion pathway - Lead processing plants may discharge their effluent into nearby rivers or other bodies of water, and children may drink river water and be exposed to hazardous metals.Part 4:
I would classify children as chronic lead exposure because when children live near lead processing plants, they are continuously exposed to small amounts of le, ad and eventually lead builds up in their bodies and has deleterious effects.In this study the independent variable is the level of public exposure to lead from lead processing factories and the dependent variable is the mentally disturbed community due to lead exposureHeavy metals including lead create reactive radicals that damage cell structures, including DNA and cell membranes. Lead also interferes with enzymes that help in the synthesis of vitamin D and interferes with enzymes that keep cell membranes intact. Because it interferes with the integrity of the membrane, damaged red blood cells become more fragile, leading to anemia.
In the brain, lead poisoning also causes loss of nerve sheaths, reduction in the number of nerves, and interferes with nerve transmission and growth. Lead also interferes with neurotransmitters, which are chemicals used by nerves to send signals to other cells. This disorder causes communication disorders between cells. A lead normally interferes with the neurotransmitter glutamate which is important for many functions, such as learning.

Neurons are cells that form a nervous system that functions to send and receive signals from the brain. They work by chemical and electrical actions that enable the transmission of signals in our body by picking up and sending electrical and chemical signals to other neurons
The transmission of impulses between one neuron and another at a synapse is mediated by the release of a chemical mediator, namely neurotransmitter released from the pre-synaptic terminal. The nerve impulse will pass through the nerve cell membrane as an action potential. At the end of the action potential period, a stronger stimulus can elicit a secondary action potential a greater change in voltage and frequency of the action potential is generated in response.

The wrist is a type of gliding joint. The wrist and ankle have gliding joints. The bones in a gliding joint can only slide over each other.
A gliding joint, also known as a plane joint or planar joint, is a kind of synovial joint that forms when two bones contact at flat or nearly flat articular surfaces.
Gliding joints allow bones to glide past one other in any direction along the joint plane — up and down, left and right, and diagonally. These joints can also rotate somewhat, although this is restricted by the form of the bones and the suppleness of the joint capsule that surrounds them.
In the appendicular skeleton, several gliding joints arise between the carpal bones of the wrist, the carpals and metacarpals of the palm, the tarsal bones of the ankle, and the tarsals and metatarsals of the foot.
These little bones form several flattened facets between one another, allowing the hands and feet to be extremely flexible.

Boreal forests are composed of a few species of coniferous evergreen trees with small, needle-shaped leaves. These trees can withstand the intense cold and long winter seasons
Some common trees found in boreal forests include spruces, firs, and pines. These trees are adapted to the cold climate of boreal regions through a variety of mechanisms, including the production of thick, waxy needles that help to retain moisture and prevent desiccation, and the ability to photosynthesize at low temperatures. Additionally, boreal trees are adapted to the long winter seasons through the development of deep root systems that help to anchor them in place and provide access to water and nutrients during the winter months.

Most of the starch stored in the cells of a potato is composed of molecules that originally entered.
Correct option is b, A polysaccharide known as starch, which is composed of many monomers known as sugar-like monosaccharides, is a polymer. One or more sugar molecules comprise all carbs.
Simple sugars are monosaccharides because they only contain one sugar molecule. Fructose, glucose, and sucrose are a few examples of these sugars. These carbohydrate compounds are consumed by the body, where they are changed into natural sugar molecules and used as fuel. Biomolecules made up of several single sugar units are known as polysaccharides or complex carbohydrates.
These units are connected by glycosidic linkages in complex carbohydrates. The majority of the molecules that make up a potato's stored starch were initially simple sugars that entered the cell. Starch and glycogen are examples of polysaccharides, which are polymers (carbohydrates) made up of many glucose molecules that are simple sugar subunits.
