Brain Anatomy, Neurotransmitters, and Perception Explained
Brain Anatomy and Regions
- Frontal Lobe / Prefrontal Cortex: Directs higher-order thinking, executive functions, planning, and impulse control. Damage results in poor judgment, impulsivity, and personality changes.
- Occipital Lobe: Dedicated to visual processing and vision.
- Parietal Lobe: Integrates sensory input and spatial awareness. Damage can lead to tactile agnosia (inability to identify objects by touch) or misjudging space.
- Temporal Lobe: Manages hearing, memory, language comprehension, and object
Shugoshin Protein Function in Chromosome Segregation
Figure 1
- a: Cells with Rec8 and Sgo1 alone can grow. When Sgo1 and Rec8 are expressed together, growth is impaired.
- b: A GFP dot marks centromere 2. In cells with Rec8 and Sgo1, the GFP marker migrates to the same side instead of separating, causing nondisjunction.
Nondisjunction: Sister chromatids fail to separate properly. - c: Quantifies nondisjunction seen in Rec8 and Sgo1, which causes a large increase in failed sister chromatid separation.
- d: Rec8-GFP normally disappears during anaphase. When Sgo1

Ultimate AP Statistics Formula and Exam Cheat Sheet
Random:
everyone has an equal chance.
Systematic:
choose every kth person.
Stratified:
divide into groups, randomly sample from each group.
Cluster:
divide into groups, randomly select entire groups.
Convenience:
choose whoever is easiest to reach. Qualitative = Categories = Eye color, Quantitative = Numbers = Height, Discrete = Counted = Number of siblings, Continuous = Measured = Weight. Common bias:
Selection bias:
sample doesn’t represent population.
Voluntary response:
people choose whether

Logistics Network Design and Factors Affecting It
Meaning of Logistics Network Design
Main Elements of Logistics Network Design
- Suppliers: Suppliers provide raw materials, components, and other resources required by an organization. Their location affects transportation cost and delivery time. Companies often consider reliable suppliers while designing their logistics network.
- Manufacturing Facilities: Manufacturing facilities are places where raw materials are converted into finished products. Their
Digital Electronics Principles, Logic Gates and Circuits
1. Universal Gates
NAND and NOR are universal gates because any logic function (AND, OR, NOT, etc.) can be built using only NAND gates or only NOR gates.
| Gate | Using NAND | Using NOR |
|---|---|---|
| NOT | Tie both inputs together: A’ = (A·A)’ | Tie inputs together: A’ = (A+A)’ |
| AND | NAND followed by a NAND-NOT | NOT each input, then NOR |
| OR | NOT each input, then NAND | NOR followed by a NOR-NOT |
NAND-NOT: A ─┬─[NAND]─ A'
└─┘
NAND-AND: A ─┐
[NAND]─[NAND(tied)]─ AB
B ─┘

Air Pollution, Solid Waste Management & Incineration Principles
Air Pollutants and Effects on Humans
Major Air Pollutants: Major air pollutants are classified as particulate matter (dust, smoke, fumes, mist), gaseous pollutants (SO2, NOx, CO, CO2, hydrocarbons), photochemical pollutants (ozone, PAN), and secondary pollutants formed by reactions in the atmosphere.
- Particulate Matter (PM10, PM2.5): Fine solid or liquid particles suspended in air, produced by combustion, industries, and vehicles.
- Sulphur Dioxide (SO2): Released from the burning of coal and fuel oil
