mitochondria

Flashcard: mitochondria are known as the powerhouse of the cell, responsible for producing energy in the form of ATP through cellular respiration.

Heat Transfer

______ is the movement of thermal energy from a warmer object to a cooler object.

Heat Transfer

 conduction

_______ is the process of heat transfer through direct contact between particles or objects.

conduction

convection

convection

______ is the transfer of heat through the movement of fluids, such as air or water, due to density differences.

radiation

Definition: ________ is the transfer of heat through electromagnetic waves, such as sunlight warming the Earth's surface without the need for a medium.

radiation

1. Examples of Heat Transfer

Examples of heat transfer include conduction, convection, and ________.

Examples of Heat Transfer

1. Land and Sea Breeze

A __________ is a local wind system caused by temperature differences between land and water. During the day, the breeze blows from the sea to the land, while at night, it reverses direction from land to sea.

1. Cold front

Cold front is a boundary where a __________ air mass displaces warmer air, leading to cooler temperatures and often stormy weather.

warm front

A warm front is a boundary of __________ air mass that is moving into an area of cooler air, leading to gradual temperature increase and often bringing prolonged precipitation.

Stationary front

A __________ front is a boundary between air masses where neither air mass is strong enough to replace the other, resulting in prolonged cloudy and rainy weather.

Occluded front

An occluded front forms when a __________ front overtakes a __________ front, leading to a mix of warm and cold air masses.

Tornado-warning signs

_____-warning signs are indications of an imminent tornado, including dark greenish skies, large hail, and a loud roar similar to a freight train.

1. Hurricane-formation and damage

A powerful tropical cyclone with sustained winds of at least 74 mph. Hurricanes form over warm ocean waters and can cause widespread destruction through high winds, heavy rainfall, storm surges, and flooding.

Earthquake

An _______ is a sudden shaking of the ground caused by the movement of tectonic plates beneath the Earth's surface.

Earthquake

types tectonic Boundaries

Types of tectonic boundaries include divergent, convergent, and transform boundaries.

1. Theory of plate tectonics

Theory of plate tectonics: A scientific theory that explains the movement of Earth's lithosphere, which is divided into several large ______ that float on the semi-fluid asthenosphere.

Theory of plate tectonics

1. Nucleus

The _______ is the central organelle in a cell that contains the genetic material and controls the cell's activities.

Mitochondria

Mitochondria are known as the powerhouse of the cell, responsible for generating energy in the form of ATP through the process of cellular respiration.

Chloroplast

Organelle found in plant cells responsible for photosynthesis, containing chlorophyll that captures sunlight to produce energy. ________

1. Cell wall

the outer layer of protection on a cell only found on plant cells

1. Cell membrane

a selective permeable membrane that is on the out side of cells

cytoplasm

a jelly like substance that suspends organelles
