Building the Ultimate You
Name 1 drug that impacts your body's ability to maintain homeostasis.
Caffeine
Name 1 species that performs Photosynthesis.
Sunflower.
What molecule contains instructions for our cells to build our proteins?
DNA
Give 1 example of an adaptation that helps an individual survive.
Finches on the Galapagos island developed a longer beak over time, which enabled them to obtain food more easily.
Give 1 example of a specific species who is a producer
Oak Tree
Name 1 example of an environmental impact on your body's homeostasis.
Cold weather lowers your body temperature. Your body shivers to heat up.
True or False. Photosynthesis is a process in which organisms utilize the energy from the Sun in order to make glucose. The by-product of this process is Carbon Dioxide.
False
Match the 4 bases to their "partner" (who pairs with who?).
Cytosine, Thymine, Guanine, Adenine
Cytosine pairs with Guanine
Thymine pairs with Adenine
What are the 2 major drivers of evolution? (All species try to _S____________ and _R______________)
Survive & Reproduce
What is the source of energy for any food chain?
The Sun
Define Homeostasis.
Maintaining a stable internal environment.
Name the difference between Anaerobic and Aerobic respiration.
Anaerobic= without oxygen
Aerobic= with oxygen
What process is responsible for forming an RNA strand that is complimentary to the DNA strand?
(Hint: Begins with a "T")
Transcription
Give 1 example of how flocking helps an individual survive.
What trophic level would you find at the second step (from the bottom) of a biomass pyramid?
Primary Consumer
True or False: A Positive Feedback Loop stops an effect from continuing.
False
Write the balanced chemical equation for cellular respiration.
6 O2 + C6H12O6 yields 6 H2O + 6 CO2 +ATP
Transcribe the following segment of DNA:
TAC-CGG-CTA-GAT
AUG-GCC-GAU-CUA
Are the wings of a bat and the forearm of a human analogous or homologous structures?
Homologous (same structure, different function)
How much energy gets transferred from one level of the Biomass Pyramid to the next?
10%
Define Negative Feedback Loop.
Given a trigger, the body systems respond in order to return the body to the stable state, and reverse the initial stimuli.
Explain the role that photosynthesis and cellular respiration play in the Carbon Cycle.
During the process of photosynthesis, organisms take CO2 out of the atmosphere and secure carbon in the biosphere. During cellular respiration, organisms move carbon from the biosphere to the atmopshere in the form of carbon dioxide.
Put the following in order from beginning to end:
Protein, Trait, DNA, RNA
DNA, RNA, Protein, Trait
Name 3 pieces of evidence for evolution
Embryological, Anatomical, Genetic
Explain why biodiversity is important to ecosystems.
Having high biodiversity enables an ecosystem to bounce back (or be resilient) from changes in order to be stable
