Aboveground biomass Correct Answer the total mass of living plants, excluding their roots; Biomes difffer substantially in the amount of aboveground biomass Biome Correct Answer ways ecologists and biodiversity scientists categorize different areas, based on distinctive and stable assemblages of species that occur in those areas; what org...

Anion - correct answer A negatively charged ion Aphanitic - correct answer An igneous rock texture that refers to the grains not visible to the naked eye, and therefore indicative of fast cooling. Aureole - correct answer The zone of metamorphosed rock surrounding an igneous intrusion and showing the effects of contact metamorphism Bar - correct answer A unit of pressure equal to 10 to the 6th dynes/cm2, approximately one atmosphere (atm) Bowen's Reaction Series - correct a...

explain how the 20 amino acids found in proteins are formed by only 4 nucleotide bases - correct answer Triplet nucleotide codons translate to amino acids. Since there are 4 types of nucleotides that can be arranged in combinations of 3, there are 4^3 = 64 possible different codons. Each codon codes for a specific amino acid, and as there are only 20 amino acid, while each codon itself can only specify one amino acid. After studying geologic maps of Cali, a researcher hypothesizes that the b...

What is a relative date? a. A date expressed as a specific unit of scientific measurement, such as days, years, centuries, or millennia. b. A date expressed relative to another (e.g., earlier, later, more recent, etc.) rather than in absolute terms. c. A date based on the occurrence of distinctive fossil assemblages in distinct strata. d. No longer useful for archaeology; absolute dates are necessary in order to provide a meaningful interpretation of an assemblage. a date expressed re...

BIO 250 FINAL EXAM VERIFIED ANSWERS 100%2023/2024 What are the three major weaknesses/ biases in the fossil record? - correct answer Geographic bias: erosion to the fossil record because of the elements -Older fossils in older earth layers have had more time for geography to change. I.e. under water or subduction Taxonomic bias: taxonomic groups with no bones or shell to form a fossil -Some groups don't fossilize well (e.g. worms) Temporal bias: things that lived a long time ago are ...

Chapter 03: The Emergence of Life True/False 1. One basic characteristic of living matter is that it is in chemical equilibrium; that is, it is in a stable, balanced condition with reciprocal reactions going on. Answer: False Page: 56 Explanation: One basic characteristic of living matter is that chemically it is not in equilibrium; that is, it is not in a stable, balanced condition with reciprocal reactions going on. Instead, in living cells energy flows take place as membranes let some ch...
