What weather comes from a warm front

Typically brings steady rain or light precipitation, followed by warmer temperatures.

What weather comes from a cold front

Cold air masses, thunderstorms, and clear skies.

What weather comes from a high pressure system

Generally clear skies and fair weather.

What weather comes from a low pressure system

Typically brings cloudy skies, precipitation, and storms.

Wha type of clouds is like an anvil

Cumulonimbus clouds, often associated with thunderstorms.

What type of cloud is blue or gray

Altostratus

What are the four main cloud types

Cumulus, Stratus, Cirrus, Nimbostratus.

After what period did dinosaurs go extinct

The Cretaceous period, approximately 66 million years ago.

Binary Fission

A form of asexual reproduction in which a single organism divides into two identical daughter cells.

Nuclear fusion

The process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Mitosis

A type of cell division that results in two genetically identical daughter cells, crucial for growth and repair in organisms.

What does Cytosine match to?

Guanine

Pancreas makes what hormone

Insulin, which regulates blood sugar levels.

What is Ohms law formula

V = IR voltage=current times resistance.

What color of star is hottest

Blue

What are the phases of a smaller star

Nebula, fusion, main sequence, Giant, white dwarf, black dwarf

What is the SI unit for frequency

The SI unit for frequency is Hertz (Hz), which measures the number of cycles per second of a periodic phenomenon.

What is a wave’s highest point called, and the distance to is from it’s resting point

The highest point of a wave is called the crest, and the distance from the crest to its resting point is referred to as amplitude.

What is the formula for work in joules

The formula for work in joules is calculated as the product of force (in newtons) and distance (in meters) moved in the direction of the force.

What is the formula for power in watts

The formula for power in watts is calculated as the rate at which work is done or energy is transferred, defined as work done (in joules) divided by time (in seconds).

What is the formula for acceleration

The formula for acceleration is calculated by dividing the change in velocity (in meters per second) by the time (in seconds) over which the change occurs.

What is the velocity formula

The velocity formula is calculated as the displacement (in meters) divided by the time (in seconds) taken to cover that displacement.

What is meosis

A type of cell division that reduces the chromosome number by half, resulting in four unique gametes, crucial for sexual reproduction.

Types of symbiosis

Interactions between different species, including mutualism, commensalism, and parasitism.

Stalactites and stalagmites form from what mineral

Deposits of calcium carbonate

What rock is on the ocean floor

Basalt

What rock hardens to form marble

Limestone

What is more complex, eukaryotes or prokaryotes

Eukaryotes

What protein carries oxygen in blood

Hemoglobin

What is the opposite of a spring tide

Neap tide

Rod shaped bacteria

Bacilli

Helium

What are some of the epochs in the Cenozoic era

Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene epochs, which are all part of the Cenozoic Era

What are the four main biological macromolecules

Carbs (simple sugars), Nucleic acids (DNA), amino acids (proteins), and lipids (fatty acids or glycerol).

What does PMAT stand for

Prophase, Metaphase, Anaphase, and Telophase in mitosis

Rain comes from what cloud category

Nimbus

Cirrus clouds

Delicate white patches, wispy and made of ice

Cumulus

Puffy white clouds

Stratus

Flat, uniform clouds that can make light rain

Nimbostratus

Thick, sun-blocking, gray clouds

Altocumulus

White or gray rolls of patch clouds

Stratocumulus

Combination of layers of stratus and cumulus

Cirrostratus

Transparent, large clouds

What is the word for glacial till that accumulates on the edges of glaciers

Lateral moraines

Entropy

The amount of wasted energy

First thermodynamic law

States that energy is neither created nor destroyed

Second thermodynamic law

All energy transfers create useless energy

Third thermodynamic law

As a balanced system approaches absolute zero, they entropy approaches a constant

Boyle’s law

A universal law that states that the pressure of a gas under a steady temperature is inversely proportional to its volume

Newton;s laws

1. Objects will not change motion unless a force reacts on it

2. F=m x a

3. Every action has an equal and opposite reacion
