Human Biology Chapter 1 (BSC-1092 HCC)

Describe the levels of
organization of life (from chemical level to most grandiose).

• molecules, atoms, cells, tissues, organ systems, species, organisms, populations, ecosystem, community, and biosphere.

• atoms, molecules, cells, tissues, organs, organ systems, organisms, species, populations, community, ecosystem, and biosphere.

• cells, atoms, molecules, tissues, organs, organ systems, organisms, species, population, community, ecosystem, and biosphere.

• atoms, cells, molecules, organs, tissues, organ systems, organisms, species, populations, community, ecosystem, and biosphere.

DNA is

• Deoxyribonucleic Acid
• DiNitrogen Acetate
• Dioxygen Nitrate Acid
• Dihydrogen Nitrate Acid

What is DNA responsible for?

• Controlling the body's metabolism
• Storing and transmitting genetic information (providing instructions for reproductions, growth, and development)

• Regulating body temperature
• Producing energy for the body

[blank] can cause variations in the instructions from DNA.

What is metabolism?

• The process of breaking down food to yield energy
• The process of converting light into energy
• The process of converting sound into energy
• The process of converting heat into energy

Answer explanation

Organisms acquire materials and energy from the environment. Metabolism is the sum of the reactions involved in these processes

All living things require [BLANK] , as it is what maintains their internal environment. When this process fails, the organism dies.

Why is evolution important in the study of Human Biology?

• It helps us understand why humans have certain features

• It provides a basis for the creation of new species
• It explains the existence of supernatural beings
• It proves that humans are the most intelligent species

(a) is the process that results in evolution and (b) to our environment over time.

• (a) Natural selection, (b) Adaptation
• (a) Mutation, (b) Resistance
• (a) Genetic drift, (b) Acclimatization
• (a) Adaptation, (b) Evolution

Answer explanation

As a species, we are influenced by natural selection and that is the process that results in evolution and adaptation to our environment over time.

Experimental design consists of a(n) (A) and a(n) (B)

• A: Hypothesis, B: Conclusion
• A: Observation, B: Experiment
• A: Experimental variable, B: Control group

• A: Theory, B: Law

Over time, multiple conclusions in a particular area may allow students to arrive at a

Answer explanation

Over time, multiple conclusions in a particular area may allow students to arrive at a theory (or a principle, or a law), such as the cell theory or the theory of evolution. The theory of evolution is a unifying concept of biology.
