Study Notes

Wind and Atmospheric Movements

Trade winds travel air masses from the west to the east.
Jet streams move air from the Pacific Ocean across the United States.
Gulf Stream influences air mass movement from the Atlantic to the Pacific Ocean.

Organisms and Biological Systems

Amoeba is an example of a single-celled organism.
Multicellular organisms require transport systems for gas exchange, nutrient supply, and energy needs.

Cardiovascular System Functions

The cardiovascular system transports gases throughout the body and plays a major role in waste elimination.

Nervous System Function

The nervous system sends electrical signals coordinating the activities of all other body systems.

Ecosystems and Organism Roles

Grass is classified as a producer in ecosystems.
Bacteria play a crucial role in recycling dead plants and animals.

Population Impact and Adaptation

Housing developments can reduce food availability for woodpecker populations.
Traits like height and intelligence can be inherited, while scars are not inherited characteristics.

Motion and Speed

A ball thrown upward experiences varying speeds: slowing down as it rises, stopping, and speeding up as it descends.
Increasing speed of a moving object is accomplished by a force acting in the same direction.

Physics of Objects

The mass of launched objects affects their speed; lighter objects like paper clips will generally move faster when the same force is applied.
Evaporation is responsible for the disappearance of water puddles after rainfall.

Chemical Solutions

Combining 10 grams of water with 5 grams of salt results in 15 grams of saltwater.

Heat Transfer

Heat from a campfire is transferred to nearby people via air conduction, allowing them to feel warmth without direct contact.

Human Body Systems

The digestive system includes structures like the esophagus, stomach, and intestines.

Ecosystem Dynamics

A drop in eagle populations could lead to overpopulation of snakes, disrupting the ecosystem balance.

Inheritance of Traits

Offspring inherit traits from both parents, including physical attributes like freckles and eye color.

Environmental Changes

Rising Pacific Ocean temperatures can cause west U.S. droughts and flooding in South America, often linked to El Niño phenomena.

Unicellular vs. Multicellular

To determine whether an organism is unicellular or multicellular, one should assess the number of cell types present.

Digestive Process

The digestive system processes food into energy.

Decomposers

Mushrooms serve as an example of decomposers in the ecosystem.

Human Impact on Wildlife

Beach development contributes to sea turtle population decline primarily through habitat loss.
