Study Notes

Stem-Cell Therapy Purpose

Samuel Bernal suggests stem-cell therapy is primarily for healing and longevity.

Types of Causes in Philosophy

The carpenter who builds a table represents the Efficient Cause.

Genetically Modified Organisms

Genetically Modified Organisms (GMOs) are also referred to as Transgenic organisms.

Stoicism Principles

Stoicism emphasizes virtue as the foundation of happiness and asserts that humans shape their own lives.

Concepts in Physics

Velocity is defined as the speed of an object along with its direction.
Acceleration is the change in velocity divided by time.
Effusion is exemplified by air escaping through a pinhole in a tire.

Gas Laws

Boyle's Law states pressure is inversely proportional to volume at constant temperature.
Charles' Law indicates volume is directly proportional to temperature at constant pressure.
The Ideal Gas Law connects volume, temperature, and pressure of an ideal gas.

Chemical Bonds and Subatomic Particles

Ionic bonds involve electrostatic attraction between positive and negative ions.
Protons and neutrons are located in an atom's nucleus.
The atomic number equals the number of protons in an element.

Nature and Technology Interactions

Modern technology often challenges natural resources.
De-development argues that wealthier nations should decrease their resource consumption.

Environmental Science Concepts

Commensalism describes a relationship where one species benefits without harming the other.
Urban growth is slower in developed countries compared to developing nations.
Erosion, weathering, and deposition are key processes in forming sedimentary rock.

Seasonal Changes

Seasons result from the tilt of Earth’s axis, affecting climate.

Ecology Events

El Niño patterns cause increased rainfall in the Pacific Coast of South America.

Mitosis and Intermolecular Forces

Mitosis stages proceed as prophase, metaphase, anaphase, and telophase.
Geckos utilize Van der Waals forces to adhere to surfaces.

Scientific Method Steps

The scientific method follows a sequence of gathering data, forming a hypothesis, questioning, developing a method, and drawing conclusions.

Astronomy and Gravitational Concepts

The Sun is positioned at the center of the solar system as theorized by Copernicus.
The Coriolis effect influences wind direction globally and shapes weather patterns.

Rock Classification

Chalk, limestone, and marble are forms of calcium carbonate formed from seashell deposits.

Environmental Conservation

Essential conservation strategies include maintaining life's support systems and sustainable resource use.

Special Characteristics of Echinoderms

Echinoderms are notable for their spiny structures and tube feet.

Issues in Climate Change

Increased carbon dioxide levels in winter relate to the higher use of coal-fired stoves.

Academic and Scientific Terms

Physical weathering involves breaking rock into smaller pieces without changing its chemical structure.
Avogadro's Law suggests volume is directly related to the amount of gas present.

Human Impact on Natural Cycles

Human activities can significantly alter both the carbon and nitrogen cycles.

Temperature defines the degree of hotness or coldness of an object, typically measured in degrees Celsius or Fahrenheit.

Instruments for Observation

A microscope utilizes lenses to observe tiny objects invisible to the naked eye.

Physical Properties of Matter

Malleability refers to the ability of solid materials to be shaped through pressing or hammering without breaking.

Biological Organization

Correct biological organization from most to least inclusive: ecosystem, community, population, individual.

Biomes and Ecological Concepts

Permafrost is not classified as a terrestrial biome; it is a permanently frozen layer of soil.
The correct order of complexity: Planet > Solar System > Galaxy > Constellation.

Cell Division

Cytokinesis occurs during the telophase stage of mitosis, finalizing cell division.

Disease Transmission

Dengue fever is transmitted by a carrier classified as arthropods under the class Insecta.

Plant Respiration

Carbon dioxide is released by plants primarily in the morning as part of their respiration process.

Ecological Interactions

Commensalism is a symbiotic relationship where one organism benefits while the other remains unaffected, exemplified by birds following army ants.

Ecological Succession

Secondary ecological succession describes the process of land formation following volcanic eruptions, like those in Hawaii.

Environmental Concerns

Increased concentrations of greenhouse gases are a primary concern related to global warming.
The Kyoto Protocol aims to reduce greenhouse gas emissions internationally to combat climate change.

Ecosystem Dynamics

In a hypothetical ecosystem, if primary consumers (worms) are eliminated, the tertiary consumer (lion) risks extinction due to lack of prey.

Food Chains

A food chain illustrates the transfer of matter and energy from one organism to another within an ecosystem.

Scientific Method

Making guesses or predictions is not a recognized step of the scientific method; proper hypothesis formulation and experimentation are essential.

Biology Branches

Ecology is the branch of biology focused on the interactions and relationships of living organisms with their environments.

Decomposition

Saprotrophs are organisms responsible for breaking down substances during decomposition, aiding nutrient recycling in ecosystems.
