Evolution & Diversity
This man is considered the father of the theory of evolution by natural selection.
Who is Charles Darwin?
This is the fastest land mammal. (+100 for including top speed)
What is a cheetah? (70-80 mph)
Plants create energy using this process.
What is photosynthesis?
Prokaryotes are comprised of these two groups.
What are bacteria and archaea?
These are the smallest units of life in the human body.
What are cells?
This is the modern, commonly accepted, definition of evolution.
What is change in allele frequencies over time?
This evolutionary mechanism acts on heritable variation within a population, increasing the frequency of alleles that confer a reproductive or survival advantage while decreasing those that are disadvantageous.
What is natural selection?
Plants turn photo energy to chemo energy through this cellular organelle.
What is the chloroplast?
Bacteria don’t have a nucleus; instead, they have this region where their DNA is located.
What is the nucleoid?
This is the largest organ in the human body.
What is the skin?
This is the source of all genetic variation on earth.
What are DNA mutations?
The common term for the circulatory fluid of an insect, which is not contained in vessels like in vertebrates.
What is hemolymph?
Plants need ovules, fertilization, and this substance containing male gametes in order to produce seeds.
What is pollen?
Shorter generation time will have this effect on the growth curve of a bacterial culture.
What is increased/faster growth rate?
This organ secretes digestive enzymes and bicarbonate into the small intestine o aid in the digestion of fats, proteins, and carbohydrates.
What is the pancreas?
This mode of evolution does not act on heritable genetic changes, but rather acts randomly on populations and has a greater effect in smaller populations.
What is genetic drift?
This group of animals is characterized by having a notochord, dorsal nerve cord, and pharyngeal slits at some stage of development.
What are chordates?
This is the plant tissue that transports water and minerals from the roots to the leaves.
What is the xylem.
Gram positive bacteria have a thick layer of this substance in their cell wall.
What is peptidoglycan?
This structure allows for both voluntary motor control and involuntary autonomic regulation by serving as a major relay center between the cerebral cortex, limbic system, and brainstem.
What is the hypothalamus?
In a population at equilibrium, 16% of individuals express a recessive trait for a given gene. The allele frequency of the recessive allele is [blank] and can be determined using the [blank].
What are q=.4 and the Hardy-Weinberg equation?
Some amphibians use this type of respiration in addition to lungs, allowing gas exchange through the skin.
What is cutaneous respiration?
Moving from the inside to the outside of a plant stem cross-section, the five key tissues are this.
What is pith -> xylem -> phloem -> cortex -> epidermis?
According to Robert Koch, these are the four criteria for determining whether a microorganism causes a specific disease.
What is: 1) The microorganism must be found in all diseased individuals, 2) it must be isolated and grown in pure culture, 3) it must cause the disease when introduced into a healthy host, 4) it must be re-isolated from the experimentally infected host.)?
This phase of the cardiac cycle begins with closure of the atrioventricular valves and ends when ventricular pressure exceeds arterial pressure.
What is isovolumetric contraction?
