What is the difference between Prokaryotic cells:

Prokaryotic cells lack the nucleus and other organelles found in eukaryotic

What is an example of a organ system:

The digestive system is composed of structures such as the stomach and small intestine

What are organs composed of:

Organs are composed of two or more different types of tissues.

Organism is to community as organ is to:

ORGAN SYSTEM:Organisms make up a community of an ecosystem. Organs make up an organ system of a body.

What is a sequence that lists organisms in the order of producer, consumer, and decomposer?

Algae are photosynthetic organisms. Many birds consume plant parts. Earthworms decompose dead materials.

An example of a stimulus that a plant would respond to is:

Plants can respond only to certain stimuli in the environment, such as sunlight.

What would be considered complex AND organized?

Red blood cell in the human body

DNA is a molecule that directly allows a living thing to:

Store information.

The process of homeostasis is:

Homeostasis is the maintenance of a relatively constant internal environment even in changing external environments."

Living systems need energy to:

Almost everything about being alive takes energy, which is why acquiring and using energy are characteristics of life.

The complexity of living systems:

Is also highly organized.. Living systems exhibit a combination of complexity and organization that is unique.

A characteristic that is representative of some, but not all, life-forms.

Movement over great distances.. Not all living things are capable of movement.

As we respire, we release CO2. The CO2 comes from

Eating food...Animals eat plants, and plants fix carbon dioxide from the atmosphere into sugars through the process of photosynthesis. Humans then eat the plants, obtaining carbon, which is then metabolized to produce CO2. The CO2 is then exhaled back into the atmosphere.

A scientist notices that a warning light has been triggered on a piece of equipment that he is using. The scientist believes that this means the light bulb has stopped working. This is a(n)

hypothesis..A hypothesis is a proposed explanation for the observation of the warning light. The actual reason may be different and would only be found through making a prediction and testing that prediction.

What is a series that is in the sequence of biological organization from the simplest to the most complex?

Cell, tissue, organ, population....These terms are in order of increasing complexity.

What is true with regard to the relationship between ecosystems and communities?

Ecosystems include the nonliving components of an environment; communities include only the living components of an environment...

Tissues are composed of ...

Cells..Tissues are groups of similar cells.

The chemical energy used by most organisms for metabolism and growth ultimately comes from......

The sun..Energy for life ultimately comes from the energy of the sun, trapped by photosynthetic organisms.

All cells have _____.

A cell membrane...All cells have a cell membrane.

Plants obtain their energy from _____.

Light...Plants use the energy of light to produce food molecules.

What would happen if an ecosystem lacked decomposers?

The ecosystem would stop functioning as nutrients became locked up in dead organic matter.

Humans are members of the _____.

Kingdom Animalia

A theory is _____.

A well-supported concept that has broad explanatory power...Theories are comprehensive and become widely accepted if they are supported by a large body of evidence.

Example of a scientific hypothesis?

My excessive urination may mean that I have high blood pressure.

Two garden plots were planted with corn. The soil was similar in each, and equal amounts of water were applied to each plot. One plot was fertilized, the other was not. The experimenters measured the yield as bushels of corn from each plot. The plot that did not receive the fertilizer was the _____.

Control plot...The "control" refers to the plot that does not receive the experimental treatment - in this case, fertilizer.

What is the correct order for the hierarchy of biological organization?

molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem

Biology is the study of _____

life

what is scientific theory

A Scientific Theory describes a well-tested explanation for a range of Phenomena.

What are the steps used in scientific methodology

Observing, asking questions, forming a hypothesis, conducting experiments, taking data, analyzing data, and drawing conclusions.

If you could check the pH of the recommened tablets you would expect to be

neutrons and protons

Water's surface tension and heat storage capacity is accounted for by its

hydrogen bonds

What is a Covalent Bond

a chemical bond that involves sharing a pair of electrons between atoms in a molecule.

What are Three Types of passive transportation

1) Osmosis
2) Simple diffusion
3) Facilitated diffusion

What is osmosis

The diffusion of water

What is active transport

sodium potassium pump
