Biological Productivity - the rate of generation of biomass in an ecosystem; western margins of continents have high prosuctivity and the Artic has the most because of high levels of upwelling and downwelling bc there is no thermocline Photosynthesis formula - 6CO2 + 6H2O + sunlight ---> C6 H12 O6 + 6O2 Photosynthesis - Inputs: Carbon Dioxide, water, sunlightOutputs: Glucose, oxygen Euphotic Zone - Upper layer of a body of water through which sunlight can penetrate and support photos...

Paraphyletic Group - Correct Answer ️️ -some (not all) of descendants of a common ancestor Polyphyletic Group - Correct Answer ️️ -organisms from distinct lineages based on shared characters, but no common ancestor Homologies - Correct Answer ️️ -si...

Alternation of generations - Cycle has BOTH multicellular haploid & multicellular diploid forms Are the most visible life stages of the land plant groups sporophytes (2n) or gametophytes (n)? - All are sporophyte except nonvascular is gametophyte Changing-environment hypothesis - offspring that are genetic clones of their parents are unlikely to thrive if the environment changes Crossing over - homologous chromosomes exchange genetic information Diploid dominant life cycle - Similar to ani...

Biological organization - ANSWER-atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere Prokaryote - ANSWER-a small unicellular organism that lacks a nucleus and membrane bound organelles; bacteria and archaea Eukaryote - ANSWER-a cell (or often multiple cells) with a nucleus and membrane-enclosed organelles that have specified functions What creates unity in the diversity of life? - ANSWER-DNA Unified because all organisms h...

define gene - a segment of DNA that codes for a functional product that influences a phenotype (mostly proteins, sometimes RNA) define mutation - changes in DNA that lead to a new or altered genes/ train, and ends up contributing to evolution explain the different levels of genetic study (molecular, cellular, organismal, population) - molecular: DNA, RNA, polypeptides/ proteins cellular: proteins affect the structure, function, and other characteristic of a cell organismal: traits of an ...

Biosphere Regions of the Earth's crust, waters, and atmosphere inhabited by living things Ecosystem a community plus the physical environment community interacting populations in a particular area organism an individual; complex individuals contain organ systems organ system composed of several organs working together organ composed of tissues functioning together for a specific task tissue a group of cells with a common structure and function cell the...

What is a megabase (Mb)? correct answers 1 million bases Is there generally a difference in the amounts of DNA when comparing the genome sizes of viruses --> prokaryotes --> eukaryotes? How does this comparison relate to complexity of these organisms? Be careful. correct answers viruses < prokaryotes < eukaryotes genome sizes does not correlate with complexity, just because an organism has a bigger genome size does not make it more complex. Eukaryotes can differ dramatically...
