Based on hierarchical organization, place the living systems in order from smallest to largest: Blue wildebeests, Black wildebeests, crocodiles, acacia trees, Blue wildebeests, Maasai Mara, Blue wildebeests and Black wildebeests, Blue wildebeest (Connochaetes taurinus),

1 - Blue wildebeest (Connochaetes taurinus) 2 - Blue wildebeests 3 - Blue wildebeests and Black wildebeests 4 - Blue wildebeests, Black wildebeests, crocodiles, acacia trees 5 - Maasai Mara

Based of hierarchical organization - put these structures in order from smallest to largest. Skeletal muscle tissue, Biceps brachii muscle, Skeletal muscle tissue, Myosin protein, Skeletal muscle cell, Muscular system

1 - Myosin protein 2 - Skeletal muscle cell 3 - Skeletal muscle tissue 4 - Biceps brachii muscle 5 - Muscular system

Based on the hierarchical organization, order these terms from smallest to largest: water, carbon, skin cell, mitochondria, DNA,

1 - carbon 2 - water 3 - DNA 4 - mitochondria 5 - skin cell

Which Kingdoms are Eukaryotes

Animalia Fungi Plantae Protista

In order to carry out essential life functions such a growth, development, and movement, a duck must eat.

Energy Utilization

If I look at 10 skin cells from my hand, each one will have a nucleus.

False

Only onion cells have a nucleus.

False

Some cells have a nucleus

False

The onion cells I looked at have a nucleus

False

Different cell types develop in a multicellular organism because each cell has its own unique set of genes.

False. Even though all cells in a multicellular organism have essentially the same genetic info, they can develop different characteristics because different genes are active in different cells

Evolutionary conservation explains the diversity of life

False. Evolutionary conservation explains the unity of life.

Information stored in inorganic molecules is used to direct the synthesis of cellular components

False. Information stored in DNA is used to direct the synthesis of cellular components

Living organisms contain unique chemical elements which are not found in non-living systems.

False. Living organisms are made of the same chemical elements that are present in non-living matter (carbon, hydrogen, etc)

Organisms are closed systems that require an input of energy in order to maintain their high level of complexity and organization.

False. Organisms are OPEN systems. In order to survive, grow, and reproduce, living organisms must take in things like energy and nutrients and they must get rid of waste products

Scientists have successfully sequenced the entire genome of humans but have not yet sequenced the entire genome of any other species.

False. Scientists have sequenced the genome of humans and of many other species.

The unity of living systems arises through evolutionary change.

False. The diversity of living organisms arises through evolutionary change

The roots of a plant grow toward a source of water.

Growth

The body temperature of a dog is more stable than the temperature of its environment

Homeostasis

A cat composed of organ system, which are composed of organs, which are composed of tissues, which are composed of cells.

Organization of Cells

A bacterial cell divides to form two new cells

Reproduction

All cells have a nucleus.

True

All living organisms are composed of one or more cells.

True

All onion cells have a nucleus

True

An input of energy is required to maintain the complexity of living systems.

True

Cells process information stored in their DNA as well as information they receive from the environment.

True

Homeostasis is possible because elaborate signaling networks coordinate the activities of different cells within an organism

True

Living systems are governed by the same principles of chemistry and physics that govern non-living systems

True

Living systems are the most complex chemical systems on earth.

True

Molecules in different organisms that perform the same function are likely to have a similar structure.

True

The energy conversions that take place in living systems are governed by the same laws of thermodynamics that govern non-living systems.

True

Underlying similarities in biochemistry and genetics support the idea that all life evolved from a single ancestor.

True

The simplest level of organization that can carry out all of the functions of life is a(n)

cell

A biological community together with its physical habitat constitutes a(n)

ecosystem

The level of organization that is more complex than an atom but less complex than an organelle is a(n)

molecule

Your brain is an example of a(n) ____________.

organ

Molecules may be assembled into a microscopic structure called a(n) ____________ which carries out specific functions within a cell.

organelle

A group of organisms that belong to the same species and live in the same place is called a(n) _______________

population

A __________ is a group of similar cells that act as a functional unit

tissue

Cells are composed of chemicals and both the structure and function of cells are regulated by the basic principles of chemistry.
