Bio Final Summaries

Evolution

________ is a generational change in populations, which can happen through natural selection: differential survival and reproduction.

DNA

Living organisms reproduce with ________, either asexually or sexually.

biome

A(n) ________ is defined by every similar ecosystem as a group.

RNA

Water is essential for all life, and so is nitrogen as it is in DNA, ________, amino acids, and proteins.

Atoms

________ make up molecules, which make up organelles and structures, which make up tissues and organs.

Photosynthesis

________ removes carbon from the atmosphere and gives it to plants and eventually animals, and respiration, combustion, and erosion put it back.

Decomposers

________ and detritivores make use of the poop.

Sunlight

________ is the main energy source for all life.

abiotic factors

The ________ are added to the community to create the ecosystem.

inference

While a(n) ________ is not necessarily fact, an observation is typically fact.

Humans

________ could be impacted by sound and could impact swarms through food competition.

chemical reactions

Since all ________ are the metabolism, anabolism crafts larger molecules and consumes energy while catabolism does the opposite.

regurgitate pellets

They can fly without noise, swallow their food whole, and ________ containing animal matter that they can not digest.

Homeostasis

________ is a response where the organisms maintain their internal environment.

Organic compounds

________ contain carbon atoms that are covalently bonded to other elements, and they can be carbohydrates, lipids, proteins, or nucleic acids.

Carbon

________ is found in all the major molecules of life.

quantitive observation

A(n) ________ requires numerical data, so it is a precise number.

dichotomous key

A(n) ________ is a guide with choices that allows one to identify something through the process of elimination.

biotic factors

An ecosystem has abiotic and ________.

qualitative observation

A(n) ________ is not numerical and describes a quality.

biogeochemical cycle

A(n) ________ is a closed cycle where paths of water, carbon, nitrogen, and phosphorus pass from the nonliving environment to organisms and back again.

Carbohydrates

________ are made of carbon, hydrogen, and oxygen at a ratio of 1: 2: 1, and they are a significant source of energy.

multicellular organisms

Living organisms gain matter and mass as growth, so cells become larger and ________ gain cells.

Carbon dioxide levels

________ in the atmosphere have risen severely over time, so uptake and return are not in balance.

carbonic acid

It is found in the atmosphere, dissolved in water to make ________, in calcium carbonate rocks, in deposits of coal, petroleum, and natural gas, and in humus (dead organic matter)

chemical bond

A(n) ________ is a force that joins atoms, and one form is a covalent bond which happens when two or more atoms share electrons to form a molecule.

South America

Africa, ________, and Australia tend to absorb carbon dioxide with their more plants and less human activity.

Sexual reproduction

________ requires a sperm and an egg cell, called fertilization.

Asexual reproduction

________ causes the offspring to be identical to the parent, while sexual gives the offspring half from each parent.

Owls

________ tend to eat small live rodents, including voles, pocket gophers, shrews, mice, and rats.

energy transfer

The ________ can be modeled in food chains, which are a series of steps in which organisms transfer energy, or in food webs, which are all of the different food chains together.

Carbon reservoirs

________ are where carbon is stored, like in the ocean, rocks, fossil fuels, and living organisms.

Exponential growth

________ happens where the rate of population growth stays the same so the population size increases steadily.

Biotic factors

________ are alive, while abiotic factors are not alive.

chemical reactions

Life depends on ________, which rely on energy usage through means of matter consumption.

There are 3 key features that we study

population size, density, and dispersion, but also growth and diversity

There are 3 patterns of dispersion, too

random, even, and clumped

Since everything in the system has always been there, there are 4 spheres

the hydrosphere, or all of the liquid and surface water of the planet (and ice), the atmosphere, or all of the gases and water vapor, the geosphere, or earths core, mantle, and crust, and the biosphere, or all of the living things
